Abstract

A dielectric-loaded loop antenna for operation at frequencies above 200 MHz has an elongate cylindrical core with a relative dielectric constant greater than 5, a pair of coextensive helical antenna elements, a coaxial feeder structure extending through the core from a proximal end to a distal end where it is coupled to the antenna elements, and a balun formed on the core cylindrical surface and connected to the feeder structure at the proximal end of the core. Each helical antenna element is bifurcated at an intermediate position so that proximally, it is formed of two generally parallel branches each of which is coupled to a respective linking path around the core to meet a corresponding branch of the other elongate element therefore forming a conductive loop between the two conductors of the feeder structure. The two conductive loops have different electrical lengths as a result of, for example, the branches being of different lengths. In a preferred embodiment, the linking paths around the core are formed by the rim of a split conductive sleeve constituting the balun. The sleeve is formed in two parts separated by a pair of longitudinally extending diametrically opposed quarter wave slits each of which extends from the space between the branches of a respective helical antenna element to a short circuited end adjacent the proximal end of the core.

Description of the invention ~ I-Field of the invention The present invention relates to a dielectric antenna that can be used at frequencies above 200mhz. The antenna has a three-dimensional antenna element structure on or adjacent to the elongated dielectric core. This core is formed of a solid 5-body material and has a relative dielectric constant greater than 5. Description of the prior art The situation of the antenna disclosed above can be known from UK Patent Gazette No. GB2292638A, which discloses a four-wire antenna, an antenna element structure having a four-spiral antenna, outside the core of a round 10-post porcelain core. A conductor path is formed on the surface. The core has an axial path 'which has a metal bushing inside and the path contains an axial path. Inside it there is a metal bushing to form a coaxial feeder structure, which is connected via a radial conductor formed on the core terminal opposite the feeder—the feeder To the spiral antenna element. The other end of the antenna element is connected to a common 15-effect ground conductor to form an electroplated sleeve surrounding the proximal portion of the core, and is connected to the outer conductor of the coaxial feeder formed by the axial via liner. The sleeve connected to the feeder structure forms a trap to isolate the spiral elements from the ground, but provides a conductive path along the edges of the interconnecting spiral elements. This antenna was originally intended to be an omnidirectional antenna to receive a circularly polarized signal. Its source may be on the top of the antenna, that is, on its axis, or on a plane perpendicular to the axis at a small tilt angle of only a few degrees. As a result, this antenna is particularly suitable for receiving satellite signals from the global positioning system GPS. 'Because this antenna can also receive signals that are vertically and horizontally polarized, it is also compatible with the Chinese National Standard (CNS) A4 specification (2Ι0 × 297) in this paper size.

Description of the Invention (L) can be applied to other wireless telecommunication devices, such as portable radios or mobile phones. The dielectric antenna particularly suitable for mobile phones is a two-wire spiral loop antenna, which includes two half-box spiral 5-shaped elements that are diametrically opposed, as described above, connected to a conductive sleeve, and a twisted loop. The resulting radiation pattern is all-round, except for the two opposite places that are in the middle of the axis perpendicular to the plane formed by the four ends of the two spiral elements. This antenna is disclosed by the British patent application NO.2309592A in which we participate together, and its content becomes a reference for a part of the patent application of the present invention. When this loop antenna is properly installed on the mobile phone handset, there is no sense to reduce the level of radiation introduced into the user's head during signal transmission. Although the antenna gain is better than many previous mobile handset antennas, it is significantly lower than the maximum central value of the resonance frequency above and below β. Therefore, one of the purposes of the present invention is to provide antennas that have a relatively wide bandwidth or can be used in two frequency bands. General Description and Use of the Invention According to the first object of the present invention, a dielectric loop antenna is provided for use at a frequency of 200 MHz or more, which includes an elongated dielectric core, and is formed by a dielectric having a relative dielectric constant greater than 5.

There is a distance of 5 distances, and then surround the core and return to the feeder connection. The electrical length of one of the paths is longer than the other path at the antenna operating frequency. Since the conductive paths of the loops have different electrical lengths, their resonance frequencies are different and can be selected as appropriate to conform to t », for example, the center of the transmission and reception frequency band of the mobile phone system. The interconnecting conductor can be formed by a quarter notch, which is provided by the feeder structure extending longitudinally along the core near the feeder connection. In a preferred embodiment, the interconnecting guide system is formed by mutually isolated portions on the trap sleeve, so each of the two loop conductive paths includes a longitudinally extending crack of the respective sleeve portion to isolate each other 'The electrical length of each crack from the respective short-circuited end to the appropriate edge of the sleeve is at least about one-fourth of the operating frequency-wavelength' Therefore the isolation between the two parts of the sleeve is extended by their connection points. Antenna element provided. In addition, each interconnecting conductor is formed by a conductive strip, which extends from the elongated antenna element to the other side that surrounds the core.

Between the two loop conductive paths The difference in electrical length can be achieved by forming two or one branches with different electrical lengths to form β. Each branch can be connected to its respective interconnecting conductor and extend around the opposite side of the core, at least in the The difference in the lengths of the paths of the elongated elements that are isolated from each other can be achieved successfully not only by arranging the branches to different lengths, but also by forming different interconnecting conductors on opposite sides of the core. Its satisfactory operation can be configured by the electrical length of each branch to be approximately 90 at the resonance frequency of the respective conductive path. [Or 15 (211 + 1) in / 4, and 11 = 0, 1, 2. ..], the input wavelength is the corresponding wavelength. The interconnecting conductor represents a low-impedance place at the operating frequency, and each 90 ° length presents a current-to-voltage conversion, which results in the The impedance is relatively high. Therefore, at the resonance frequency of-in the conductive path, the excitation of this path occurs simultaneously with other paths (single 20 or plural). Then the resonance at rain or more clear different frequencies can be This is due to the fact that each branch bears its load to the minimum when another conductive path resonates.

Description of the invention (pc860442.twp-7/31 The significance of the printed set of edges of the printed work system and the edges of the sleeves of the other parts of the Central Standards Bureau of the Ministry of Economic Affairs is obviously different when the longitudinal position is different. In the short part of the sleeve, the electrical length can be increased, so the frequency at which effective trapping occurs can approach the resonance frequency of the longer of the conductive 5 channels of the ring. Since the terminal of the elongated antenna element is placed in a common plane, the edges of the entire sleeve are effectively stepped, just as the connection around one side of the antenna and the opposite side around the opposite side are in different longitudinal positions of the core. This means that each cutlery antenna element has two branches, one shorter than the other, and the shorter green part of the sleeve that can be connected is closer to the distal end of the core, and the other longer branch is connected The green part of the edge is farther than the near end. This produces conductive loops of different lengths and different resonance frequencies. The branching parts of each component are parallel to each other and close to each other, ending at the bottom of the edge of the sleeve and their respective components.

Description of the Invention (^) Attached to a metal antenna element extending vertically 丨 〇A, i⑽ outside the cylindrical shape of the ceramic core 12 On the surface.

In order to form a complete conductive loop, each antenna element branch 10AA, 10AB, 10BA, 10BB is connected to an edge source (20RA, 20RB) of a common effective grounding conductor 20, and the connection method is to surround the core with a conductive sleeve A proximal portion of the portion 12. This sleeve 205 is further connected to the bush 16 of the axial passage 14 in the form of a panel 22 on the proximal end surface 12P of the core 12. The conductive loops formed by the spiral elements 10, 10B (including individual branches), the radial elements 10AR, 10BR, and the edges of the parts 20feA, 20RB of the sleeve 20 are drawn through the core The 10-wire structure extending from the near end to the antenna elements 10A and 10B is fed at the far end of the core. The antenna then has a bifurcated screw-like structure fed by the terminal. At least from the upper part or the distant part, the sleeve 20 is split into corresponding parts 20A and 20B, which are respectively opened at an angle of approximately 180 ° at the mandrel 12A, and are separated from each other by longitudinal cracks 20S. 15 20S is a crack of the conductive material of the sleeve 20 extending from the proximal end of the antenna element branch, such as ΑΑΑΕ, 10ABE, 10BAE '10BBE, to the short-circuit end 20SE.

The effect is explained as follows: This common plane is indicated by the chain line 24 in Fig. I. The feeder is connected to the antenna element structure and the feeder structure and is also in a common plane 24. In the antenna shown in FIG. 1, the conductive sleeve 24 covers the adjacent portion of the antenna core 12, thereby surrounding the entire structure between the feeder structure 16, 18 and the metal liner 16 filling the sleeve 20 and the axial path 14.

The combination of the sleeve 20 and the panel 22 and the formation of a wave trap cause the signal of the transmission line formed by the feeder structures 16, 18 to be in an unbalanced state near the antenna and approximately in the plane of the upper edges 20RA, 20RB of the sleeve 20 The transition between the equilibrium states of an axial position. In order to achieve this effect, the axial length of some of the exaggerated cylinders 20A and 20B should be arranged so that the core material below it has a higher dielectric constant, and the electrical length of the trap is about 1/4 or 90 ° in the working frequency band of the antenna. Owing to the initial shortening effect of the antenna core material and the annular space surrounding the inner conductor 18, a kind of green dielectric material 19, which has a smaller dielectric constant and is far from the sleeve 20, is a feeder structure. The system has a short electrical length.

A T ___ _ B7_ 5. Description of the Invention (A) At least approximately balanced. A further effect of the sleeve 20 is that for the signals in the working frequency range of the antenna, the green portion 20RA, 20RB of the side of the sleeve 20 can effectively isolate the ground represented by the outer conductor 16 of the feeder structure. This 5 means that most of the current circulating between the antenna elements 10A and 10B is limited to the edge portion. Therefore, the sleeve 20 behaves like the same isolation trap to reduce the phase distortion phenomenon caused by the unbalanced current bow in the antenna. The preferred material for the antenna core 12 is a pin-based material. This material has a relative dielectric constant of 36 and is also known for its size and electrical properties (K) stability to temperature changes. Media loss is negligible. The core can be manufactured withdrawable or pressed. % The antenna elements 10A, 10B, 10AR, and 10BR are metal conductor paths formed on or near the outer cylindrical and distal surfaces of the core 12 and each path width is at least the same as the thickness of its working length. These paths can be obtained by initially plating the surface of the core 12 with a metal layer and then selectively removing the metal layer to expose the core in accordance with the desired circular shape. Alternatively, metallic materials can be applied with selective deposition or printing techniques. In all cases, forming a path as a monolithic element outside the dimensionally stable core results in an antenna with dimensionally stable elements. 20 The person who knows what is known from the above description can know that the longitudinally extending antenna element 10A '10B together with the part of the sleeve 20A, 20B edge part 20RA' 20RB, forming a ring-shaped conductive path at the antenna's operating frequency Range, each ring-shaped path is isolated from the earth ^ Therefore, the first ring-shaped conductive path is opened at the feeder connection on the distal end surface of the core 12D.

Description of the Invention (β) First, it returns to the feeder via the radial conductor 10AR, the upper part of the element 10A, the branch 10BA of the lower part of the element 10A, the distal end of the element 10B, and finally the radial conductor 10BR. Another conductive path passes through element 10AR, the distal portion of element 10A, the other branch 10AB of element 5A, the other portion 20RB of the edge of sleeve 20, and this time extends around the opposite edge of core 12 The diagram diameter is from the edge portion 20RA, then passes through the other branch 10BB of the antenna element 10B, the distal end portion of the element 10B, and finally returns to the feeder line via the radial element 10BR. 10 The two conductive paths have different physical and electrical lengths, so this is because the branches of the first conductive path 10AA, 10BA are longer than the branches of the second conductive path ioab, 10BB ', and because of the edge part 20RA starts farther than the other edge part 20RB at the feeder connection at the distal end of the core 12D. In this way, the different heights of I5 between the two edge portions 20RA and 20RB cause the edge green to have a stepped outline along with the antenna element branches of each element 10A, 10B connected to the sleeve 20 on the opposite sides of the stepped edge, as shown in Figure 1.

That is, when two pairs of parallel-connected paragraphs are all connected in series to the antenna element 10A, 10B and the distal portion of the sleeve 20, the substance represented by the edge portion 20ra, 20b 5 of the sleeve 20 This is the case between the earth and the earth. As indicated, the branch sections have an electrical length of Cm, and 2M, depending on whether they are longer or shorter. Depending on the part of the ring-shaped conductive path, the longer one has a resonance frequency corresponding to the wavelength; I, and the shorter one has a spectral frequency corresponding to the wavelength hair. 10 Due to the isolation effect of the sleeve 20 when the antenna resonates When in the ring, it mainly restricts the current to the side green portions 20RA and 20RB, which represent the position of the maximum current. For signals with wavelengths in the range of I and 12, the quarter-wave branch 10AA 10BB acts as a current-to-voltage converter, so at the point where each antenna element is split, there is a maximum voltage of 15 and the impedance of each branch looking out tends to be infinite, as shown in Figure 2. As a result, when a conductive When the resonant loop resonates, the impedance seen by the other branch is higher (if the order of volts and hair is the same). This means that the resonance of one loop is not significantly affected by the conductors of the other loops. In other words, the isolation between the two resonance modes The degree is shown in two clear paths.

It is a stepped sleeve The cylinder edges 20RA and 20RB not only generate two different ring-shaped paths surrounding the opposite sides of the core, so that there may be two resonance frequencies. At the same time, it can also divide the trap represented by the sleeve 20 into two sections. Parallel resonance path. As should be understood, each longitudinal slit 20S in the sleeve 20 is arranged at the center frequency within the required frequency range and has an electrical length in the quarter wavelength range, which is for this purpose. The reason is that they are formed into an L-shape in the embodiment of Fig. 1. Such a shape is preferable 10 in that it can obtain a sufficient length than other shapes, such as a zigzag path with a slit, or it can be extended around. The panel 22 on the proximal edge of the antenna enters the proximal end 12P of the core 12. The quarter wave slit 20S has the function of isolating the upper ranges of the two parts of the sleeves 20A, 20B from each other, so that the two Longer of the conductive loops The current I5 is at the edge green part 20RA, while the current in the shorter one is limited to the edge part 20RB. The purpose of isolation is to change the zero impedance of the short-circuit terminal 20SE to a high impedance to some of the sleeves 20A, 20B. The water criterion is the same as that of the two edge portions 20RA and 20RB. As shown in Figure 1, when the rear ends of the cracks 20S are arranged to face each other, the shorter of the two-part sleeves 20A and 20B ( 20A) The effect of the restriction on the current path is introduced between the edge portion 20RA of the core and the sleeve at the proximal end of the core and the feeder structure 16. This limitation increases the longitudinal impedance of some sleeves 20A and adds an inductor It is more effective, and the world tends to reduce the frequency.

This ring-shaped conductive path includes the edge of this part of the sleeve 20 A. In this case, it refers to the longer β 5 of the ring-shaped conductive path. The ability to work at separated frequencies is effective. Refer to Figure 3 A, 3B and 3C. If the crack is too short to effectively isolate the upper range of the two-part sleeve 20A, 20B ', there is a relatively weak The spike is formed at the higher of the two resonance frequencies' as shown in Fig. 3A.
