Description

液晶組成物以及使用其的液晶元件、感測器、液晶透鏡、光通訊設備及天線Liquid crystal composition and liquid crystal element, sensor, liquid crystal lens, optical communication equipment and antenna using the same

本發明是有關於一種液晶組成物以及使用其的液晶元件、感測器、液晶透鏡、光通訊設備及天線。The invention relates to a liquid crystal composition and a liquid crystal element, a sensor, a liquid crystal lens, an optical communication device and an antenna using the liquid crystal composition.

作為大多用於顯示器用途的液晶的新穎用途,在汽車等移動體與通訊衛星之間進行電波的收發且使用液晶的天線備受矚目。先前,衛星通訊使用拋物線天線(parabola antenna),但於在汽車等移動體中使用的情況下,必須隨時將拋物線天線朝向衛星方向,需要大的可動部。但是,使用液晶的天線藉由液晶運作,可改變電波的收發方向,因此不需要移動天線本身,天線的形狀亦可成為平面。As a novel application of liquid crystals that are mostly used for displays, antennas that use liquid crystals to transmit and receive radio waves between mobile objects such as automobiles and communication satellites are attracting attention. Previously, parabola antennas were used for satellite communications, but when used in moving objects such as cars, the parabola antenna must be directed toward the satellite at any time, requiring a large moving part. However, the antenna using liquid crystal can change the direction of radio wave transmission and reception by operating the liquid crystal, so there is no need to move the antenna itself, and the shape of the antenna can also be flat.

一般而言,對於汽車等的自動運轉而言,需要下載高精度三維(Three-dimensional,3D)地圖資訊的大量資料。但是,若為使用液晶的天線,則藉由將該天線組裝於汽車中,即便無機械可動部亦能夠自通訊衛星下載大量資料。衛星通訊中使用的頻帶約為13 GHz帶,與至今為止的液晶顯示器用途中使用的頻率大不相同。因此,對液晶的要求物性亦大不相同,天線用液晶所要求的Δn為0.4左右,運作溫度範圍為-40℃~120℃。Generally speaking, for the automatic operation of automobiles and the like, it is necessary to download a large amount of high-precision three-dimensional (3D) map information. However, in the case of an antenna using liquid crystal, by assembling the antenna in a car, a large amount of data can be downloaded from a communication satellite even if there is no mechanical movable part. The frequency band used in satellite communications is approximately the 13 GHz band, which is quite different from the frequency used in the previous liquid crystal display applications. Therefore, the required physical properties of liquid crystals are also very different. The required Δn of liquid crystals for antennas is about 0.4, and the operating temperature range is -40°C to 120°C.

另外,作為汽車等移動體的自動運轉用感測器,使用液晶的紅外線雷射圖像識別及測距裝置亦備受矚目。對該用途的液晶所要求的Δn為0.2~0.3,運作溫度範圍為-40℃~120℃。In addition, infrared laser image recognition and distance measurement devices using liquid crystals are also attracting attention as sensors for automatic operation of moving objects such as automobiles. The required Δn for liquid crystals for this purpose is 0.2 to 0.3, and the operating temperature range is -40°C to 120°C.

進而,已知構成顯示出0.2~0.4的高Δn的液晶組成物的液晶性化合物大多相容性低。因而,亦重要的是選擇相容性高的液晶性化合物。Furthermore, it is known that most of the liquid crystal compounds constituting a liquid crystal composition exhibiting a high Δn of 0.2 to 0.4 have low compatibility. Therefore, it is also important to select a liquid crystal compound with high compatibility.

對此,作為天線用液晶的技術,例如可列舉專利文獻1。In this regard, as a technique of liquid crystal for antennas, for example, Patent Document 1 can be cited.

另外,於非專利文獻1中,提倡使用液晶材料作為高頻器件的構成成分。 [現有技術文獻] [專利文獻]In addition, in Non-Patent Document 1, the use of a liquid crystal material as a constituent component of a high-frequency device is advocated. [Prior Art Literature] [Patent Literature]

[發明所欲解決之課題] 對於天線等電磁波的相位調變中使用的液晶,要求開發能夠對微波或毫米波的電磁波進行更大的相位控制、顯示出更高的折射率各向異性(Δn)的液晶組成物。進而,於以天線為首的高頻用途的液晶組成物的領域中,亦會於室外使用或於汽車等移動媒體中驅動,因此要求進而兼具廣驅動溫度範圍與低驅動電壓的液晶材料。因此,對於該用途的液晶組成物,要求兼具用於提高驅動溫度上限溫度的高液晶相上限溫度(TNI )、用於提高對高頻電磁波的相位調變能力的高Δn、以及用於以低電壓驅動的低臨限電壓(Vth)。然而,於所述專利文獻1記載的液晶組成物中,幾乎未示出Δn的具體值,另外,即便示出Δn,亦僅示出被認為顯示出高驅動電壓的Δε小的液晶組成物,未揭示兼具高Δn與低驅動電壓的液晶組成物。[Problems to be Solved by the Invention] Liquid crystals used in phase modulation of electromagnetic waves such as antennas require the development of greater phase control of microwave or millimeter wave electromagnetic waves and higher refractive index anisotropy (Δn ) Liquid crystal composition. Furthermore, in the field of liquid crystal compositions for high-frequency applications such as antennas, they are also used outdoors or driven in mobile media such as automobiles. Therefore, a liquid crystal material that has a wide driving temperature range and a low driving voltage is required. Therefore, for the liquid crystal composition for this purpose, it is required to have both a high liquid crystal phase upper limit temperature (T NI ) for increasing the upper limit temperature of the driving temperature, a high Δn for improving the phase modulation ability to high-frequency electromagnetic waves, and Low threshold voltage (Vth) driven by low voltage. However, the liquid crystal composition described in Patent Document 1 hardly shows a specific value of Δn, and even if Δn is shown, only a liquid crystal composition with a small Δε, which is considered to exhibit a high driving voltage, is shown. A liquid crystal composition having both high Δn and low driving voltage is not disclosed.

因此,本發明的課題在於提供一種於能夠對微波或毫米波的電磁波進行更大的相位控制的液晶材料中,具有高TNI 、高Δn且具有用以實現元件的低驅動電壓的低Vth的向列液晶組成物、及使用其的液晶元件、感測器、液晶透鏡、光通訊設備及天線。 [解決課題之手段]Therefore, the subject of the present invention is to provide a liquid crystal material capable of greater phase control of microwave or millimeter wave electromagnetic waves, which has a high T NI , a high Δn, and a low Vth for realizing a low driving voltage of the element. Nematic liquid crystal composition, and liquid crystal element, sensor, liquid crystal lens, optical communication equipment and antenna using it. [Means to solve the problem]

Hereinafter, the slot array section 6 will be described using FIG. 4. The slot array portion 6 has a structure in which power is supplied through a coaxial line provided in the center portion thereof. Therefore, the power supply part 12 is provided in the center part of the slot array part 6 shown in FIG. In addition, the groove array portion 6 has a plurality of grouped grooves 8 (hereinafter referred to as a “groove pair”) formed on the surface of the disc-shaped conductor P. The groove pair 8 has a structure in which two rectangular cutout portions are arranged in a "eight" shape. In more detail, two rectangular parallelepiped-shaped grooves 8 are arranged orthogonally, and one groove of the groove pair 8 is arranged at an interval of 1/4 wavelength with respect to the other groove. In this way, circularly polarized waves with different rotation directions can be transmitted and received according to the azimuth angle of the antenna.

再者,本說明書中,將兩個槽8稱為槽對8,將一個槽8簡稱為槽8,將槽及槽對的總稱稱為槽(對)8。In addition, in this specification, two grooves 8 are referred to as groove pairs 8, one groove 8 is simply referred to as groove 8, and the collective term of grooves and groove pairs is referred to as groove (pair) 8.

槽對8自圓板狀的導體基板P的中心部朝向放射方向外側以螺旋狀形成有多個。而且,槽對8以沿著螺旋相鄰的槽對8間的距離均固定的方式形成於圓盤型的基板表面。藉此,可使相位在槽陣列部6的正面一致而增強電磁場,且可在正面形成筆型波束(pencil beam)。A plurality of groove pairs 8 are formed spirally from the center of the disc-shaped conductive substrate P toward the outside in the radial direction. In addition, the groove pair 8 is formed on the surface of the disk-shaped substrate so that the distance between the groove pairs 8 adjacent to each other along the spiral is constant. In this way, the phase can be aligned on the front surface of the slot array portion 6 to enhance the electromagnetic field, and a pencil beam can be formed on the front surface.

再者,圖3及圖4中,將槽8的形狀的一例表示為長方體的形狀,但本發明的槽8的形狀並不限定於長方體,可採用圓形、橢圓形、多邊形等公知的形狀。另外,圖3及圖4中,作為槽8的一例,示出了槽對的態樣,但本發明的槽8並不限定於槽對。進而,示出了使圓板狀的導體基板P的表面的槽8的配置為螺旋狀的例子,但槽8的配置並不限定於螺旋狀,亦可將槽8配置為例如後述的圖8所示般的同心圓狀。In addition, in FIGS. 3 and 4, an example of the shape of the groove 8 is shown as a rectangular parallelepiped shape, but the shape of the groove 8 of the present invention is not limited to a rectangular parallelepiped, and well-known shapes such as a circle, an ellipse, and a polygon can be used. . In addition, in FIGS. 3 and 4, as an example of the groove 8, the aspect of the groove pair is shown, but the groove 8 of the present invention is not limited to the groove pair. Furthermore, an example is shown in which the arrangement of the groove 8 on the surface of the disc-shaped conductor substrate P is spiral, but the arrangement of the groove 8 is not limited to the spiral shape, and the groove 8 may be arranged as, for example, FIG. 8 described later. Concentric circles as shown.

本發明的供電部12具有接收電磁波及/或放射電磁波的功能。而且,本發明的供電部12只要是將由作為放射元件或入射元件的貼片9捕捉電波而產生的高頻電力向接收機傳輸的部分,或者為了供給高頻電力而連接放射元件與供電線的部分,則並無特別限制,可利用公知的供電部及供電線。圖3及圖4中示出同軸供電部作為一例。The power supply unit 12 of the present invention has a function of receiving electromagnetic waves and/or radiating electromagnetic waves. Furthermore, the power supply unit 12 of the present invention should only be a part that transmits high-frequency power generated by capturing radio waves by the patch 9 as a radiating element or incident element to the receiver, or connects the radiating element and a power supply line in order to supply high-frequency power. Part, there is no particular limitation, and a well-known power supply unit and power supply line can be used. As an example, the coaxial power supply unit is shown in FIGS. 3 and 4.

如圖3所示,貼片陣列部7包括:圓板體Q,具有多個長度為L、寬度為W的方形形狀的貼片9;以及液晶層(未圖示),填充在與槽陣列部6之間。本實施形態的貼片陣列部7是所謂的微帶天線的結構,是以長度L與1/2波長的整數倍一致的頻率共振的共振器。As shown in FIG. 3, the patch array portion 7 includes: a disc body Q, a plurality of square-shaped patches 9 having a length L and a width W; and a liquid crystal layer (not shown), which is filled with the groove array部6 between. The patch array section 7 of the present embodiment has a structure of a so-called microstrip antenna, and is a resonator whose length L is resonant at a frequency that coincides with an integer multiple of 1/2 wavelength.

再者,圖3中,作為貼片9的一例,示出了長度為L、寬度為W的方形形狀的貼片9,但貼片9的形狀並不限定於四邊形,亦可為圓形形狀的貼片9。圖5中示出了圓形形狀的貼片9的實施形態作為本發明的另一實施形態。Furthermore, in FIG. 3, as an example of the patch 9, a square-shaped patch 9 with a length of L and a width of W is shown. However, the shape of the patch 9 is not limited to a quadrilateral, and may be a circular shape.的贴片9。 The patch 9. Fig. 5 shows an embodiment of a circular patch 9 as another embodiment of the present invention.

圖5是本發明的天線本體10的俯視圖,更詳細而言,是於自貼片陣列部7觀察天線本體10的情況下,相對於圓板體Q的主面而垂直投影貼片9、供電部12、槽對8的圖。因此,由虛線表示貼片9、供電部12及槽對8。另外,於貼片9的形狀為圓形形狀的情況下,一般而言,可以被稱為TM11 模式的電磁場分佈來運作。如圖5所示,貼片9的投影體與槽對8的投影體重合,因此可理解設置於圓板體Q上的貼片9相對於圓板狀的導體P的表面上所形成的各個槽8相對配置的狀態。如上所述,藉由利用相對於各個槽8對應地配置各個貼片9的結構,可藉由電磁耦合供電方式自槽8向貼片9供電,或者自貼片9向槽8傳播入射電波。因此,可提供能夠發送及/或接收電波的天線。5 is a plan view of the antenna body 10 of the present invention. In more detail, when the antenna body 10 is viewed from the patch array section 7, the patch 9 and the power supply are projected perpendicularly with respect to the main surface of the disc body Q Section 12, the figure of the slot pair 8. Therefore, the patch 9, the power supply unit 12, and the slot pair 8 are indicated by broken lines. In addition, when the shape of the patch 9 is a circular shape, generally speaking, it can be operated by an electromagnetic field distribution called a TM 11 mode. As shown in FIG. 5, the projection body of the patch 9 coincides with the projection of the groove pair 8. Therefore, it can be understood that the patch 9 provided on the disc body Q is formed on the surface of the disc-shaped conductor P. The relative configuration of slot 8. As described above, by using the structure in which each patch 9 is arranged corresponding to each slot 8, power can be supplied from the slot 8 to the patch 9 by the electromagnetic coupling power supply method, or the incident radio wave can be propagated from the patch 9 to the slot 8. Therefore, an antenna capable of transmitting and/or receiving radio waves can be provided.

一般而言,使用同軸線等一般的傳輸線路或平面型傳輸線路來對貼片陣列部7的放射元件(例如貼片9)進行供電的方法大致分為直接連接供電方式及電磁耦合供電方式兩種。因此,作為本發明的供電方式,可列舉:直接連接供電方式,其是藉由將傳輸線路直接連接於貼片9(放射元件)來激勵放射元件的方法;以及電磁耦合供電方式,其是不直接連接傳輸線路與貼片電極(放射元件),而藉由在終端開放或短路的供電線路的周圍產生的電磁場來激勵貼片電極(放射元件)的方法。本發明中,示出電磁耦合供電方式的態樣。Generally speaking, the method of using a general transmission line such as a coaxial line or a planar transmission line to supply power to the radiating element (for example, the patch 9) of the patch array section 7 is roughly divided into a direct connection power supply method and an electromagnetic coupling power supply method. kind. Therefore, as the power supply method of the present invention, a direct connection power supply method, which is a method of exciting a radiation element by directly connecting a transmission line to the patch 9 (radiation element), and an electromagnetic coupling power supply method, which are not The transmission line and the patch electrode (radiation element) are directly connected, and the patch electrode (radiation element) is excited by the electromagnetic field generated around the power supply line whose terminal is open or short-circuited. In the present invention, the aspect of the electromagnetic coupling power supply method is shown.

本實施形態中,利用(同軸)供電部12的供電線路為終端開放,因此產生該供電線路的終端與節點一致的電流駐波。藉此,產生包圍該供電線路((同軸)供電部12)般的磁場,藉由該磁場入射至槽8,而將槽(對)8激勵。而且,藉由因槽(對)8的激勵而產生的磁場入射至貼片9,而將貼片9激勵。由於激勵強度最大是入射至槽8的磁場最大時,因此較佳為於自供電線路((同軸)供電部12)產生的磁場最大的位置(電流駐波的波腹)形成槽(對)8。In the present embodiment, the power supply line using the (coaxial) power supply unit 12 is open to the terminal, and therefore, a current standing wave in which the terminal of the power supply line coincides with the node is generated. Thereby, a magnetic field surrounding the power supply line ((coaxial) power supply part 12) is generated, and the magnetic field is incident on the slot 8 to excite the slot (pair) 8. Furthermore, the patch 9 is excited by the magnetic field generated by the excitation of the slot (pair) 8 being incident on the patch 9. Since the maximum excitation intensity is when the magnetic field incident on the slot 8 is the largest, it is preferable to form the slot (pair) 8 at the position (the antinode of the current standing wave) where the magnetic field generated from the power supply line ((coaxial) power supply part 12) is the largest .

本發明的天線的較佳態樣是將徑向線槽陣列與貼片天線陣列組合而成的結構。The preferred aspect of the antenna of the present invention is a structure formed by combining a radial slot array and a patch antenna array.

接著,使用圖5所示的天線本體10的剖面圖即圖6來說明天線本體10的實施形態。圖6理所當然是表示天線的結構的概略圖。Next, an embodiment of the antenna body 10 will be described using FIG. 6 which is a cross-sectional view of the antenna body 10 shown in FIG. 5. Naturally, FIG. 6 is a schematic diagram showing the structure of the antenna.

如圖6所示,天線本體10包括:圓板狀的第二基板14、自中心部朝向放射方向外側形成有多個槽(對)8的圓板狀的第一基板13(與圓板狀的導體P對應;亦稱為槽陣列基板)、設置於第二基板14及第一基板13之間的第一電介質層17、設置於圓板狀的第一基板13及圓板狀的第二基板14的中心部的供電部12、圓板狀的第三基板15(與圓板體Q對應;亦稱為貼片基板)、安裝於第三基板15的貼片9(放射元件或入射元件)、以及設置於第三基板15及第一基板13之間的液晶層16。另外,供電部12經由供電線12a與設置於控制基板的發送機及/或接收機電性連接。而且,各個貼片9對應於各個槽對8。As shown in FIG. 6, the antenna body 10 includes a disc-shaped second substrate 14, and a disc-shaped first substrate 13 (and a disc-shaped Corresponding to the conductor P; also known as the slot array substrate), the first dielectric layer 17 provided between the second substrate 14 and the first substrate 13, the first substrate 13 provided on the disc-shaped substrate and the second disc-shaped substrate The power supply part 12 at the center of the substrate 14, the disc-shaped third substrate 15 (corresponding to the disc body Q; also referred to as a patch substrate), and the patch 9 (radiating element or incident element) mounted on the third substrate 15 ), and a liquid crystal layer 16 disposed between the third substrate 15 and the first substrate 13. In addition, the power supply unit 12 is electrically connected to a transmitter and/or a receiver provided on the control board via a power supply line 12a. Also, each patch 9 corresponds to each slot pair 8.

此處所謂的「(各)貼片9對應於(各)槽對8」,是指如所述圖5的說明所示,相對於第二基板14的主面而垂直投影貼片9的投影面與槽(對)8重合。換言之,是指相對於第三基板15的主面而垂直投影槽(對)8的投影面與貼片9重合。The so-called "(each) patch 9 corresponds to (each) groove pair 8" here refers to the projection of the patch 9 perpendicular to the main surface of the second substrate 14 as shown in the description of FIG. 5 The face coincides with the groove (pair) 8. In other words, it means that the projection surface of the vertical projection groove (pair) 8 overlaps the patch 9 with respect to the main surface of the third substrate 15.

另外,第一基板13、第二基板14及第三基板15較佳為具有相同面積的圓板體。In addition, the first substrate 13, the second substrate 14, and the third substrate 15 are preferably circular plate bodies having the same area.

於圖6中,描述了由(同軸)供電部12供電的電波(箭頭)成為圓筒波而在第一電介質層17內向放射方向外側傳播的期間,自槽(對)8向液晶層16傳輸的情況。而且,若如圖4所示,槽(對)8被配置成使所謂的「八」字型的正交的兩個槽錯開1/4波長,則可產生圓極化波。如上所述,藉由電磁耦合供電方式而將槽(對)8激勵,藉此自槽(對)8產生的磁場入射至貼片9而將貼片9激勵。其結果,貼片9可放射出指向性高的電波。In FIG. 6, it is described that the radio wave (arrow) supplied by the (coaxial) power supply unit 12 becomes a cylindrical wave and propagates in the first dielectric layer 17 to the outside in the radial direction, and is transmitted from the groove (pair) 8 to the liquid crystal layer 16 Case. Furthermore, as shown in FIG. 4, if the groove (pair) 8 is arranged so that two orthogonal grooves of the so-called "eight" shape are shifted by 1/4 wavelength, a circularly polarized wave can be generated. As described above, the slot (pair) 8 is excited by the electromagnetic coupling power supply method, whereby the magnetic field generated from the slot (pair) 8 is incident on the patch 9 and the patch 9 is excited. As a result, the patch 9 can radiate radio waves with high directivity.

另一方面,於接收入射電波的情況下,根據收發可逆的定理,與所述相反地,貼片9接收到入射電波後,經由設置於該貼片9正下方的槽(對)8而將入射電波傳播至供電部12。On the other hand, in the case of receiving incident radio waves, according to the reversible theorem of transmission and reception, in contrast to the above, the patch 9 receives the incident radio waves and passes through the slot (pair) 8 provided directly below the patch 9. The incident radio wave propagates to the power supply unit 12.

圓極化波與線性極化波不同,是電場方向隨著時間經過而旋轉的電波,分類為在全球定位系統(global positioning system,GPS)或電子收費(electronic toll collection,ETC)中使用的右旋圓極化波、及在衛星無線電廣播等中使用的左旋圓極化波,本發明的天線中,任一極化波均可接收。Circularly polarized waves are different from linearly polarized waves. They are electric waves in which the direction of the electric field rotates with the passage of time. They are classified into the right ones used in the global positioning system (GPS) or electronic toll collection (ETC). For the circularly polarized wave and the left-handed circularly polarized wave used in satellite radio broadcasting, etc., any polarized wave can be received in the antenna of the present invention.

藉由向貼片9與第一基板13之間的液晶層16施加電壓,可改變液晶層16的液晶分子的配向方向。其結果,液晶層16的介電常數發生變化,因此槽(對)8的靜電電容發生變化,結果可控制槽(對)8的電抗及共振頻率。換言之,藉由控制液晶層16的介電常數,可調節槽8的電抗及共振頻率,因此可控制藉由調節槽(對)8及貼片9的激勵而進行的對各貼片9的供電。藉此,能夠調節經由液晶層16的放射電波。因此,例如,亦可設置薄膜電晶體(thin film transistor,TFT)等調節向液晶層16施加的電壓的施加電壓調節部件。另外,藉由改變液晶層16的液晶分子的配向方向,折射率發生變化,作為其結果,透過液晶層16的電磁波的相位發生偏移,作為其綜合結果,能夠進行相位陣列控制。By applying a voltage to the liquid crystal layer 16 between the patch 9 and the first substrate 13, the alignment direction of the liquid crystal molecules of the liquid crystal layer 16 can be changed. As a result, the dielectric constant of the liquid crystal layer 16 changes, and therefore the electrostatic capacitance of the groove (pair) 8 changes. As a result, the reactance and resonance frequency of the groove (pair) 8 can be controlled. In other words, by controlling the dielectric constant of the liquid crystal layer 16, the reactance and resonant frequency of the slot 8 can be adjusted, so the power supply to each patch 9 by the excitation of the adjustment slot (pair) 8 and the patch 9 can be controlled. . Thereby, it is possible to adjust the radio waves radiated through the liquid crystal layer 16. Therefore, for example, a thin film transistor (TFT) or the like may be provided with an applied voltage adjusting member that adjusts the voltage applied to the liquid crystal layer 16. In addition, by changing the alignment direction of the liquid crystal molecules of the liquid crystal layer 16, the refractive index changes. As a result, the phase of the electromagnetic wave passing through the liquid crystal layer 16 is shifted. As a result of this, the phase array control can be performed.

第一基板13及第二基板14的材料只要為銅等導體則並無特別限制。另外,第三基板15的材料並無特別限制,根據使用態樣,可使用玻璃基板、亞克力基板、陶瓷(氧化鋁)、矽、玻璃布(glass cloth)鐵氟龍(Teflon)(註冊商標)(聚四氟乙烯(polytetrafluoroethylene,PTFE))等公知的材料。第一電介質層17的材料可根據所期望的相對介電常數適宜選擇公知的材料,亦可為真空。進而,貼片9的材料只要為銅、銀等導體則並無特別限制。The material of the first substrate 13 and the second substrate 14 is not particularly limited as long as it is a conductor such as copper. In addition, the material of the third substrate 15 is not particularly limited. Depending on the usage, glass substrate, acrylic substrate, ceramic (alumina), silicon, glass cloth, Teflon (registered trademark) can be used. (Polytetrafluoroethylene (PTFE)) and other well-known materials. The material of the first dielectric layer 17 can be suitably selected from a known material according to the desired relative permittivity, and it can also be a vacuum. Furthermore, the material of the patch 9 is not particularly limited as long as it is a conductor such as copper or silver.

接著,使用圖7來說明天線本體10的另一實施形態。圖7中所示的實施形態是天線本體10的槽陣列部6的部分與圖6所示的實施形態不同的態樣。於圖7中,天線本體10包括:於其中一個表面形成有多個槽(對)8的中空體的第一基板13;收容於該中空體的第一基板13的內部的圓板狀的第二基板14、第一電介質層17及供電部12;圓板狀的第三基板15;安裝於第三基板15的貼片9;以及設置於第三基板15及第一基板13之間的液晶層16,且供電部12設置於第一基板13的另一個未形成多個槽(對)8的表面與第二基板14之間,並且設置於第一基板13及圓板狀的第二基板14的中心部。另外,供電部12經由供電線12a與設置於控制基板的發送機及/或接收機電性連接。而且,各個貼片9對應於各個槽對8。另外,於圖7中,中空體的第一基板13的兩側面部向中空體的外側突出,具體而言,具有相對於水平方向成45°的傾斜面。Next, another embodiment of the antenna body 10 will be described using FIG. 7. The embodiment shown in FIG. 7 is a part of the slot array portion 6 of the antenna body 10 different from the embodiment shown in FIG. 6. In FIG. 7, the antenna body 10 includes: a first substrate 13 of a hollow body with a plurality of grooves (pairs) 8 formed on one surface; The second substrate 14, the first dielectric layer 17 and the power supply part 12; the disc-shaped third substrate 15; the patch 9 mounted on the third substrate 15; and the liquid crystal provided between the third substrate 15 and the first substrate 13 The layer 16, and the power supply portion 12 is provided between the other surface of the first substrate 13 where the plurality of grooves (pairs) 8 are not formed and the second substrate 14, and is provided on the first substrate 13 and the disc-shaped second substrate The center of 14. In addition, the power supply unit 12 is electrically connected to a transmitter and/or a receiver provided on the control board via a power supply line 12a. Also, each patch 9 corresponds to each slot pair 8. In addition, in FIG. 7, the side surfaces of the first substrate 13 of the hollow body protrude to the outside of the hollow body, and specifically, have an inclined surface at 45° with respect to the horizontal direction.

如圖7中所示,由(同軸)供電部12供電的電波(箭頭)成為圓筒波而在第一電介質層17內向放射方向外側傳播。而且,傳播的圓筒波被中空體的第一基板13的兩側面部反射,藉此繞過第二基板14的圓筒波被變換為自圓板狀的第一基板13的外周朝向中心的行進波(箭頭),於第一電介質層17內傳播。此時,行進波自槽(對)8傳輸至液晶層16。藉此,與圖6所示的實施形態同樣地,貼片9被激勵,可放射出指向性高的電波。As shown in FIG. 7, the electric wave (arrow) fed by the (coaxial) power feeding unit 12 becomes a cylindrical wave and propagates to the outside in the radial direction within the first dielectric layer 17. In addition, the propagating cylindrical wave is reflected by the side surfaces of the first substrate 13 of the hollow body, whereby the cylindrical wave that bypasses the second substrate 14 is converted into a circular plate-shaped first substrate 13 from the outer periphery to the center. The traveling wave (arrow) propagates in the first dielectric layer 17. At this time, the traveling wave is transmitted from the groove (pair) 8 to the liquid crystal layer 16. Thereby, similar to the embodiment shown in FIG. 6, the patch 9 is excited, and a radio wave with high directivity can be radiated.

另一方面,於接收到入射電波的情況下亦同樣地,貼片9接收到入射電波後,經由設置於該貼片9正下方的槽(對)8而將入射電波傳播至供電部12。 接著,使用圖8~圖10來對天線本體10的又一實施形態進行說明。於以上所述的圖5~圖7的天線本體10的實施形態中,對在第一基板13與第三基板15之間均勻地設置液晶層16的天線本體10的結構進行了說明。另一方面,於圖8~圖10的實施形態中,對在分別配置有貼片9與槽8的空間內(以下為密閉區域20)填充有液晶層16的天線本體10的結構進行說明。On the other hand, when the incident radio wave is received, the patch 9 receives the incident radio wave and propagates the incident radio wave to the power supply unit 12 through the slot (pair) 8 provided directly below the patch 9. Next, another embodiment of the antenna main body 10 will be described using FIGS. 8 to 10. In the above-mentioned embodiments of the antenna body 10 of FIGS. 5 to 7, the structure of the antenna body 10 in which the liquid crystal layer 16 is uniformly provided between the first substrate 13 and the third substrate 15 has been described. On the other hand, in the embodiments of FIGS. 8 to 10, the structure of the antenna body 10 filled with the liquid crystal layer 16 in the space in which the patch 9 and the groove 8 are respectively arranged (hereinafter, the sealed area 20) will be described.

圖8是表示本發明的天線本體10的實施形態的一例的俯視圖。更詳細而言,圖8是於自貼片陣列部7觀察天線本體10的情況下,相對於圓板體Q的主面而垂直投影貼片9、供電部12、槽8的圖。因此,與圖5同樣地,由虛線表示貼片9、供電部12及槽8。圖8中,方形形狀的貼片9與一個長方體形狀的槽8分別對應於密閉區域20而配置。另外,如圖8所示,貼片9的投影體與槽8的投影體重合,因此於貼片9的正下方形成有槽8。藉此,圖8所示的天線本體10的實施形態可藉由電磁耦合供電方式自槽8向貼片9供電,或者自貼片9向槽8傳播入射電波。因此,可提供能夠發送及/或接收電波的天線。Fig. 8 is a plan view showing an example of an embodiment of the antenna body 10 of the present invention. In more detail, FIG. 8 is a view in which the patch 9, the power feeding portion 12, and the groove 8 are projected perpendicularly with respect to the main surface of the disc body Q when the antenna body 10 is viewed from the patch array portion 7. Therefore, similar to FIG. 5, the patch 9, the power supply unit 12, and the groove 8 are indicated by broken lines. In FIG. 8, the square-shaped patch 9 and the one rectangular parallelepiped-shaped groove 8 are respectively arranged corresponding to the sealed area 20. In addition, as shown in FIG. 8, the projection body of the patch 9 coincides with the projection of the groove 8, and therefore the groove 8 is formed directly under the patch 9. Thereby, the embodiment of the antenna body 10 shown in FIG. 8 can be powered from the slot 8 to the patch 9 by means of electromagnetic coupling power supply, or the incident radio waves can be propagated from the patch 9 to the slot 8. Therefore, an antenna capable of transmitting and/or receiving radio waves can be provided.

另外,如圖8中所示,於本實施形態中,貼片9及槽8自圓板體Q的中心朝向圓板體Q的外周方向配置成同心圓狀。因此,藉由同軸模式供電,會出現圓錐波束,因此於圓板體Q的正面相位一致,電磁場可相互增強。In addition, as shown in FIG. 8, in this embodiment, the patch 9 and the groove 8 are arranged concentrically from the center of the disc body Q toward the outer circumferential direction of the disc body Q. Therefore, by supplying power in the coaxial mode, a conical beam will appear. Therefore, the phase of the front surface of the circular plate body Q is consistent, and the electromagnetic fields can be mutually enhanced.

In addition, the power supply unit 12 is electrically connected to a transmitter and/or a receiver provided on the control board via a power supply line 12a. Furthermore, each patch 9 corresponds to each groove 8, at least one patch 9, at least one groove 8 and liquid crystal layer 16 are present in each enclosed area 20, and each of the plurality of enclosed areas 20 passes through the sealing wall 21, the sealing wall 23, The wall 24 is sealed to be isolated.

圖9中雖未示出,但根據需要,亦可於各密閉區域20內,例如於第一基板13上設置控制液晶層16的電壓的TFT(薄膜電晶體)。藉此,可以主動方式控制液晶層16的電壓的施加。另外,視需要,亦可於各密閉區域20內設置配向膜,用以固定構成液晶層16的液晶分子的配向方向。作為所述配向膜,可於第一基板13與液晶層16間設置容易向液晶分子的垂直方向配向的垂直配向膜或者容易向液晶分子的水平方向配向的均勻配向膜。例如可列舉聚醯亞胺配向膜、光配向膜等。Although not shown in FIG. 9, if necessary, a TFT (Thin Film Transistor) for controlling the voltage of the liquid crystal layer 16 may be provided in each enclosed area 20, for example, on the first substrate 13. Thereby, the application of the voltage of the liquid crystal layer 16 can be controlled in an active manner. In addition, if necessary, an alignment film may be provided in each enclosed area 20 to fix the alignment direction of the liquid crystal molecules constituting the liquid crystal layer 16. As the alignment film, a vertical alignment film that is easy to align in the vertical direction of liquid crystal molecules or a uniform alignment film that is easy to align in the horizontal direction of liquid crystal molecules can be provided between the first substrate 13 and the liquid crystal layer 16. For example, a polyimide alignment film, a photo-alignment film, etc. can be mentioned.

接著,使用圖8所示的天線本體10的沿B-B線切斷的剖面圖即圖10來說明本實施形態的密閉區域20。再者,圖10理所當然是表示密閉區域20的概略圖。Next, the enclosed area 20 of this embodiment will be described using FIG. 10 which is a cross-sectional view of the antenna body 10 shown in FIG. 8 taken along the line B-B. Furthermore, FIG. 10 is a schematic diagram showing the enclosed area 20 as a matter of course.

如圖10所示,密閉區域20是由密封壁24、緩衝層22及第一基板13與第三基板15將上下四方包圍的密閉空間,在內部至少一個貼片9與至少一個槽8以相對的方式設置於同一密閉空間內,且填充有液晶層16。於本實施形態中,密封壁24可由公知的絕緣體等形成。另外,緩衝層22可由公知的電介質材料等形成。As shown in FIG. 10, the sealed area 20 is a sealed space surrounded by the sealing wall 24, the buffer layer 22, and the first substrate 13 and the third substrate 15 in four directions. At least one patch 9 and at least one groove 8 are opposed to each other. The method is set in the same enclosed space and filled with the liquid crystal layer 16. In this embodiment, the sealing wall 24 can be formed of a well-known insulator or the like. In addition, the buffer layer 22 may be formed of a known dielectric material or the like.

圖10中雖未示出,但根據需要,亦可於密閉區域20內,例如於第一基板13上設置控制液晶層16的電壓的TFT(薄膜電晶體)。藉此,可以主動方式控制液晶層16的電壓的施加。若對該利用主動方式的驅動方法進行更詳細的說明,則例如可列舉:以貼片9為共用電極,且以第一基板13為畫素電極,藉由形成於第一基板13上的TFT來控制貼片9與第一基板13之間的電壓,從而控制液晶層16的液晶分子的配向的方法;或者,以第一基板13為畫素電極,且於第一基板13上形成電極層及TFT,控制貼片9與第一基板13之間的電壓,從而控制液晶層16的液晶分子的配向的方法;進而,於第一基板13上設置梳齒電極及TFT,藉由該TFT來控制液晶層16的液晶分子的配向的方法等。再者,以主動方式控制液晶層16的電壓的施加的方法並不限定於所述方法。另外,此時,亦可於各密閉區域20內設置配向膜,用以固定構成液晶層16的液晶分子的配向方向。作為所述配向膜,可於第一基板13與液晶層16之間設置容易向液晶分子的垂直方向配向的垂直配向膜或者容易向液晶分子的水平方向配向的均勻配向膜。Although not shown in FIG. 10, if necessary, a TFT (Thin Film Transistor) for controlling the voltage of the liquid crystal layer 16 may be provided in the enclosed area 20, for example, on the first substrate 13. Thereby, the application of the voltage of the liquid crystal layer 16 can be controlled in an active manner. If the driving method using the active mode is described in more detail, for example, the patch 9 is used as a common electrode, and the first substrate 13 is used as a pixel electrode, and TFTs formed on the first substrate 13 To control the voltage between the patch 9 and the first substrate 13 so as to control the alignment of the liquid crystal molecules of the liquid crystal layer 16; alternatively, the first substrate 13 is used as a pixel electrode and an electrode layer is formed on the first substrate 13 And TFT, a method of controlling the voltage between the patch 9 and the first substrate 13, thereby controlling the alignment of the liquid crystal molecules of the liquid crystal layer 16; further, comb-shaped electrodes and TFTs are provided on the first substrate 13, and the TFT is used to A method of controlling the alignment of liquid crystal molecules of the liquid crystal layer 16 and the like. In addition, the method of actively controlling the application of the voltage of the liquid crystal layer 16 is not limited to the above-mentioned method. In addition, at this time, an alignment film may also be provided in each enclosed area 20 to fix the alignment direction of the liquid crystal molecules constituting the liquid crystal layer 16. As the alignment film, a vertical alignment film that is easy to align in the vertical direction of liquid crystal molecules or a uniform alignment film that is easy to align in the horizontal direction of liquid crystal molecules may be provided between the first substrate 13 and the liquid crystal layer 16.

為了使液晶層16同步,可對向貼片9與第一基板13之間的液晶層16施加的電壓進行調變。例如,如上所述,藉由使用主動方式控制對液晶層16的施加電壓,槽8的靜電電容發生變化,結果可控制槽8的電抗及共振頻率。槽8的共振頻率與自在線路中傳播的電波放射的能量具有相關關係。因此,藉由調整槽8的共振頻率,槽8實質上不與來自供電部12的圓筒波能量耦合,或者與圓筒波能量耦合並放射至自由空間。此種槽8的電抗及共振頻率的控制可在形成有多個的密閉區域20的各個中進行。換言之,藉由控制液晶層16的介電常數,可藉由TFT來控制對各密閉區域20內的貼片9的供電。因此,可控制發送電波的貼片9及不發送電波的貼片,因此能夠調節經由液晶層16的放射電波的發送及接收。 [實施例]In order to synchronize the liquid crystal layer 16, the voltage applied to the liquid crystal layer 16 between the patch 9 and the first substrate 13 can be adjusted. For example, as described above, by actively controlling the voltage applied to the liquid crystal layer 16, the electrostatic capacitance of the cell 8 is changed, and as a result, the reactance and the resonance frequency of the cell 8 can be controlled. The resonance frequency of the slot 8 has a correlation with the energy radiated by the radio wave propagating through the line. Therefore, by adjusting the resonance frequency of the groove 8, the groove 8 is not substantially coupled with the cylindrical wave energy from the power supply unit 12, or is coupled with the cylindrical wave energy and radiated to the free space. Such control of the reactance and resonance frequency of the groove 8 can be performed in each of the enclosed regions 20 formed with a plurality of them. In other words, by controlling the dielectric constant of the liquid crystal layer 16, the power supply to the patch 9 in each enclosed area 20 can be controlled by the TFT. Therefore, it is possible to control the patch 9 that transmits radio waves and the patch that does not transmit radio waves, and therefore it is possible to adjust the transmission and reception of the radiated radio waves through the liquid crystal layer 16.
