Description of the Invention (Clever) Background of the Invention: Field of the Invention: The present invention relates generally to the field of high-frequency antennas, especially to the use of low-cost manufacturing technology to construct dual The field of high frequency planar high frequency antennas. Background: The most important goal of the wireless communication industry is to provide antennas with the following characteristics: (1) the lowest manufacturing cost possible with consistent performance, (2) high gain, and (3) high directivity. A conventional dipole antenna fed in anti-phase to each member of a pair of quarter-wavelength radiators produces a generally unidirectional radiation field pattern in a plane perpendicular to the axes of the antennas. However, it has been considered a challenge to provide such an omnidirectional structure on a substantially flat and low-cost plane such as a printed circuit board. Existing attempts to achieve such planarity and performance rely on through-holes through the substrate to connect a plurality of conductive planes, thereby significantly increasing the cost of the antenna. Extending a flat design over a wide frequency range has proven to be even more difficult, because many designs only work in a narrower frequency range. Increasing the gain of an omnidirectional antenna is a common goal. Designing an array of stacked omnidirectional antennas often results in gain gains. Each antenna element must be properly spaced and the correct amplitude and phase (usually in phase) must be fed into each antenna element in order to increase the gain. Narrowing the beam width elevation angle, so focusing the same amount of energy on a narrower part, can achieve additional gain.

Description of the invention (2) In the existing equipment In g ten, when the frequency is changed, the phase difference between the two poles will be changed because the feeders have different lengths. For example, US Pat. Feed in. " Other designs require structures with through holes through the substrate. U.S. Patent 5,70 8,44 6 discloses an antenna which attempts to provide a substantially omnidirectional transmission field pattern in a plane perpendicular to the respective radiation theft axes. This patent does not disclose a corner reflector antenna array that can be driven by a coaxial feed line. The antenna array includes a right-angled reflector having first and second reflecting surfaces. A dielectric substrate is located adjacent to the first reflective surface, and includes a first and a second opposing substrate surface and a plurality of bipolar elements, each bipolar element including a first disposed on a surface of the first substrate. A semi-bipolar, and a second semi-bipolar arranged on the surface of the second substrate. A two-wire connection network disposed on the surfaces of the first and second substrates provides a signal to the plurality of bipolar elements. A printed circuit balanced-unbalanced converter is used to connect the center and outer conductor of a coaxial feed line to each section of the connection network arranged on the first and second substrate surfaces, respectively. However, in order to connect the coaxial cable to the connection network, U.S. Patent 5,708,446 needs to construct a through hole through the substrate. Since the through hole passes through the substrate, additional manufacturing steps are required, and thus the cost of the antenna is greatly increased. In addition, other attempts require several branch feed structures, further increasing the number of manufacturing steps, and thus increasing the cost of the antenna.

Description of the Invention (3) (Please read the notes on the back before filling out this page) There is currently a need to use fewer parts to assemble the feed structure to reduce labor costs. The current process requires manual labor in the assembly of the feed-in components. Therefore, human error enters the assembly process, and quality control must be used to detect such human error and minimize human error. This approach increases the cost of the feed structure. The performance of this manually assembled feed structure will also be inconsistent. Printed by the Intellectual Property Office of the Ministry of Economic Affairs (for example, U.S. Patent 6,037,9 1 1) discloses a phased array antenna, which includes: a dielectric substrate; a plurality of bipolar devices, each bipolar device Comprising a first and a second element, the first elements are printed on a front surface, and the first elements are directed in a first direction, and the second elements are printed on a rear surface; and a metal belt device The metal tape device includes a first circuit printed on the front surface and coupled to the first element, and a second circuit printed on the rear surface and coupled to the second element. A reflector device is also Spaced apart from the back surface of the dielectric substrate and parallel to the back surface, and a low-loss material is located between the reflector device and the back surface, so the first and second lines respectively include a plurality of first And the second circuit part, and these first and second circuit parts are connected to each other with several T connectors. However, in order to provide a balanced omnidirectional performance, US patent 6,037,9 1 1 needs to utilize several T-joints provide a balanced feed structure. These T-joints increase the complexity of the design and still increase the cost of the antenna. Finally, more complex high-frequency antennas have a high-loss line structure and therefore require an expensive Dielectric substrate. Due to the simplification of production and components and the paper size applicable to the Chinese National Standard (CMS) A4 specification (210X 297 mm) · 6-565967 A7 _- B7 ^ 一 —— ____ ^ V. Description of the invention (4) Low cost of raw materials, so the cost of this antenna is much lower than more complex high-frequency antennas. (Please read the precautions on the back before filling out this page.) Until now, dual-mode (aka dual-band) is most commonly implemented in low frequencies. Antennas. Some exemplary dual-mode antennas include: a dual-mode cellular phone antenna capable of operating at 900 and 1 800 MHz (megahertz) as disclosed in US Patent 6, 198, 4 4 3, and US Patent 6,204,826. A dual-band antenna disclosed on a substrate, and a dual-mode antenna such as a dual-mode blade antenna disclosed in U.S. Patent 4,438,437. Some previous designs use lumped discrete elements Isolate the received frequency band. At high frequencies, because the components deviate from the ideal model, it is impossible to make a device with a reasonable degree of accuracy and repeatability under realistic conditions, which makes this type of implementation (generally Designing for "notch" is difficult. The design proposed by the present invention provides a simple and low-cost solution to this challenge. Invention description: Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economics to solve the problem Disadvantages of the prior art, the present invention provides several embodiments of a dual-mode substantially planar antenna. This antenna uses a monopole, dipole, and pole dipole array structure to receive and transmit high-frequency signals. An opposite conductive strip line layer is arranged on an opposite surface of an insulating (dielectric) substrate of the printed circuit board. In one embodiment, a planar double-sided dipole antenna design is extended by adding additional lengths of conductive strip lines connected to each main bipolar element by a plurality of inductors to operate in two frequency bands. It is based on the required resonant frequency (CNS) A4 specification (210 X297 mm) ~ ^ ~ ~ 565967 A7 B7 V. Description of the invention (5) The length of these strip lines is determined. At high frequencies, the I capacitor of each inductor provides sufficient capacitance, and an LC concave wave / @ ”skin circuit is formed. This method eliminates the need for an additional capacitor on the substrate, thereby reducing the cost of the antenna. In another embodiment, a series-fed planar high-frequency antenna has a plurality of bipolar elements disposed on opposite sides of a substrate. Each bipolar system is bifurcated along a horizontal axis. One half of the bipolar system is disposed on one side of the substrate, and the other half is disposed on the opposite side. One half of each bipolar line is electrically connected to a feed branch that is not related to the other half. A plurality of bipoles can be distributed symmetrically along a main feeder. In order to work in both frequency ranges, extra length conductive strip lines are connected to each bipolar element via an inductor soldered between the main bipolar element and the extra length conductive strip line. The feed network preferably feeds these bipolars in phase. Similarly, a two-mode parallel-fed planar high-frequency antenna can be constructed. It is arranged on opposite sides of an insulating (dielectric) substrate with opposite conductive tape layers. Each bipolar system is bifurcated along a horizontal axis, one half of which is disposed on one side of the substrate, and the other half is disposed on the opposite side of the substrate. Half of each bipolar line is electrically connected to a feed branch that is not related to the other half of the bipolar line. The feed branch on each side of the substrate feeds a 'half' of each bipolar from a common center point with an equidistant feeder (ie, "parallel" feeds half of each bipolar ). This method provides a wider working range, because even when the frequency changes, the bipolars must be fed into the same phase. By connecting an additional conductive strip line to each bipolar element with an inductor, the antenna can apply the Chinese National Standard (CNS) A4 specification (21〇X 297 mm) at two paper sizes (please (Please read the notes on the back before filling in this page) ^ Clothing thread

Description of Invention (6) Work on different frequency ranges. According to an embodiment of the present invention, the inductors are prefabricated inductors welded between the main bipolar elements and the extended conductive strip lines. In an alternative embodiment, the sensors may be formed directly on the substrate using a spiral structure. The spiral structure can be, for example, a square "Manhattan," a spiral pattern or a circular spiral pattern. If additional capacitance is needed, because a spiral structure inductor has lower parasitic capacitance, it can be used in the dielectric. A thin plate is formed on each side of the substrate, and a discrete capacitor is added. Another type of dual-mode antenna proposed by the present invention is a dual-mode monopole. A monopole is a half of a bipole, and the other half is Replaced by a ground plane. The ground plane is required for proper operation of the unipolar. The dual-mode unipolar is manufactured in a manner similar to the bipolar, in a manner that lies between the two printed parts One of the series inductors, or a printed notch circuit that includes a spiral inductor and a parallel thin-plate capacitor. It can be implemented on either type of ground plane (coplanar with or unipolar to the unipolar) Brief description of the drawings: The present invention will be easily understood by referring to the following detailed description and the accompanying drawings.

For a substrate with a thickness of 0.5 mm and a dielectric constant of 3.4, a, all of these dimensions are typical. For high-frequency operation, each inductor contains sufficient parasitic capacitance, and forms an LC notch wave / notch circuit with the inductor. Therefore, a "notch circuit" is provided to these additional Bipolar element. This approach allows the antenna to operate in two different frequency ranges based on the length of the additional conductive strip lines and the chirp of the inductors. For example, using only these sensors without any additional external capacitors, the antenna can be constructed to operate in two frequency bands, 2.4 GHz and 5.5 GHz. The preferred inductor is still a thick film inductor, and its inductance 値 ranges from 5.6 to 6.8 NaH. An alternative embodiment of the invention is shown in Figs. 7-9. In FIG. 7, a planar antenna (70) includes two layers of conductive (preferably metal) strip lines arranged on opposite sides of an insulating substrate (not shown) serving as a dielectric layer. .

Description of the invention (17) 92) "Parallel" feed in a similar way A plurality of half-wavelength bipolar elements (72b), (74b), (76b), (78b), and the feed structure (92) (please read the precautions on the back before filling this page) feed a common feed In point (94). Feeders (96), (98), (100), (102) of the same length are connected to these bipolar elements from the common infeed point (94). Inductors (138), (140), (142) and (144) connect the bipolar elements (72b), (74b), (76b), (78b) to the extended conductive strip lines (122b), (124b), (126b), and (128b), respectively. To ensure balanced omnidirectional performance, the bipolars are positioned symmetrically near the feeding structures (80) and (92). The tapered sections (106) and (1 08) and the lower section (11 0) A balanced-unbalanced converter structure (104) provides the balanced performance characteristics required for such feed structures.

Printed by the Property Bureau's 8th Industrial Cooperative, as shown in Figure 9, the structures shown in Figures 7 and 8 are arranged symmetrically (along the horizontal and vertical directions) on the opposite sides of the substrate. Figure 9 is an antenna structure A composite diagram of the figure (for clarity) does not show the substrate. In this figure, the common feed points (82), (94) are obviously aligned symmetrically, and the bipolar elements are not Overlap (that is, the component (72a) is lower than the component (72b)). For a better implementation working in the 2.4 GHz and 5.5 GHz frequency bands, this paper size applies the Chinese National Standard (CNS) A4 specification (2) 0X297 mm ) ~ 565967 A7 ______ B7 V. Description of the invention (18) (Please read the notes on the back before filling in this For example, the dimensions of the antenna elements are shown in Fig. 9. The width of the bipolar elements is 1.8 mm, and the distance from adjacent elements is 8.4 mm. The length of the main bipolar elements is 5mm。 13.8 mm, and the length of the extension element is 6.5 mm, and the interval between the main element is 0.5 mm. The main feeders have a width of 1 mm and the feeders of the same length have a width of 0.8 mm. The length of each feeder of the same length is 20.65 mm, and the width of the common feed point is 0.7 mm. The distance between the ends of these feeders (vertical direction) is 42.7 mm. The cones of the balanced-unbalanced converter structures (106) and (ι〇8) are 5 ha. An appropriate dimension of the substrate is a thickness of 0.5 mm. Printed by the Consumer Cooperative of the Intellectual Property Office of the Ministry of Economic Affairs As described herein, this parallel feed embodiment can operate over a wider frequency range than other designs. In order to obtain the signal elevation angle (signal elevati〇n), the two bipolars must be fed in phase (a multiple of 3 60 °). In other designs, when the frequency is changed, the phase difference between the two dipoles will change because the feed structures have different lengths. However, in this parallel feed design, because all dipoles are fed with a feeder of the same length, even when the frequency is changed, the bipoles are still fed with the same relative phase. In this way, the working range is about ± 6% of the nominal center frequency of the antenna, whereas previous designs were usually limited to the working range of ± 2% of the nominal center frequency. In addition, because the antenna (such as (1), (3), (70)) provides a low-loss line structure, a standard-quality medium can be used for the substrate (not shown in the figure), so This has the advantage of low cost without significantly reducing the efficiency of the antenna. The thickness of this substrate (not shown in the figure) is the largest paper size applicable to the Chinese National Standard (CNS) A4 ^ grid (210X297 mm) ~ ~ 565967 A7 B7 ----5. Description of the invention (19) oi mm to 0.7 mm to provide sufficient stiffness to support the antenna structure. Due to the simplification of production and components and the low cost of raw materials, the cost of this antenna is much lower than the cost of more complex high-frequency antennas. In one embodiment, the antenna is produced without a substrate, but the increased cost is associated because the substrate embodiments are low cost and have higher reliability. An alternative inductor configuration is shown in Fig. 10A. Such an inductor can be used in any embodiment of the invention. Instead of a pre-made inductor, a “Manhattan spiral” structure can be used. An inductor (200) is constructed in a Manhattan spiral structure including a substantially rectangular conductive line (250), and the Manhattan spiral structure can be directly applied to a substrate of the antenna. Although a Manhattan spiral structure is shown in the figure, the inductor may be formed in a spiral shape. When compared with the embodiment using a preformed inductor, the inductor component and the labor cost can be reduced by manufacturing the inductor together with the antenna on the substrate. One end of the inductor (200) is directly connected (at (201)) to one side of the bipolar element (190). However, because one end of the inductor (200) is actually the center of the structure, a through hole (202) is provided to connect one end of the inductor to a line (203), which is also connected to One side of the bipolar element (192). The conductive line (203) is on the opposite side of the substrate, and a second through hole (204) is provided to connect the line (203) to the bipolar element (192). Fig. 10B is a side view of one of the Manhattan spiral inductors shown in Fig. 10A. The figure shows through-holes (202) and (204) connecting the Manhattan spiral structure (200) and the antenna element to the line (203).

Description of the invention (2〇 ) 〇 When using the Manhattan spiral structure, the parasitic capacitance may not be sufficient to provide a properly tuned LC trap circuit for some applications. In these cases, an additional capacitor can be provided. In one embodiment, the additional capacitor is a prefabricated component connected between the bipolar (190) and (192). Other additional discrete or external capacitors can also be used. As shown in FIG. 11, it is preferable to form the additional capacitor on the substrate. In this embodiment, the inductor is formed in the manner described with reference to FIG. 10A. A first capacitor thin plate (205) is formed on the same substrate surface as the inductor (200), and the first capacitor thin plate (205) is connected to one side of the bipolar element (192). A second capacitor thin plate (206) is formed on the opposite surface of the substrate (dielectric) (for example, the first and second capacitor thin plates are arranged at substantially opposite positions, but the positions are on the substrate Opposite sides), and a series of through holes (207) through the substrate connects the second capacitor thin plate (206) to one side of the bipolar element (1 90). Therefore, the LC trap circuit is formed using three through holes. However, other configurations of vias, insulation layers, and connections can also be used. Figure 12 shows the inductor and capacitor solution according to Figure 11 applied to a series-fed planar design antenna (1 200). Note that three vias (1210), (1220), (1230) are used for each LC trap circuit (1240). In order to reduce the number of through holes, the bipolar element extension (for dual-band operation) can be formed on the opposite surface of the substrate by the autonomous bipolar element. An example is shown in FIG. 13. In this embodiment, the paper size is applicable on one side of the substrate.

Inductor (200) on the description of the invention (21) And one end of the inductor (200) is directly connected to the point (201) of the bipolar element (190) on the surface. A center connector of the inductor (200) is connected to the line (203) via a through hole (202). Lines (203) on the opposite side of the substrate are connected to other bipolar elements (254) on the opposite side of the substrate. A first capacitive element (250) is formed on the same substrate surface as the inductor, and the first capacitive element (250) is directly connected to the bipolar element (1 90) on the surface. Similarly, a second capacitive element (252) is formed on the opposite surface of the substrate, and the second capacitive element (252) is directly connected to the bipolar element (254). Therefore, a single through hole (202) can be used to form the combination of the capacitor and the inductor. Figure 14 illustrates a curved unipolar (also referred to as a one-dimensional tip-loaded unipolar) according to an embodiment of the present invention. The curved monopole (1400) is constructed by using a first frequency element (1440), an LC trap circuit (1430), and a second frequency element (1420). The first frequency element (1440) is preferably a 5.5 GHz monopole, and the second frequency element (1420) is preferably a 2.4 GHz extension element. The combined components can be up to 25 mm in length, and the individual components have a length equal to 1/4 of their individual frequency. The curved monopole antenna (1 400) includes: a rear extension element (1450) for adjusting the frequency band characteristic of 5 GHz; and a base part (1440). The first frequency element (1440) preferably has the following components: The frequency element is raised to a distance of about 5-8 mm from a ground plane (1460). The lengths of (1440), (1450), and (1455) depend on the height (H). When η becomes longer, (1440), (1450), and (1 45 5) become shorter.

Invention Description (22) Circuit Board A radio frequency circuit is also included to generate a radio frequency signal to be broadcast by a bent monopole antenna (1400). Usually the ground plane is perpendicular to the plane of the monopole. The bent monopole antenna (1 400) is connected to the circuit via feeders, preferably in the form of carrier coaxial cables. The bent monopole may be fed, for example, by a coaxial cable, a microstrip conductor, or other feeders. The bent monopole antenna (1400) also includes an LC trap circuit (1430), and a single standard may be used. The inductor assembly builds the LC trap circuit (1430). The choice of inductor component is based on its parasitic capacitance. The inductance and parasitic capacitance combine to form an LC trap circuit, which has a resonant frequency, so when a higher frequency signal is applied to the antenna, the signal is only applied by the first frequency element (1 440) broadcast. Likewise, when a lower frequency signal is applied to the antenna, the combination of these two antenna elements broadcasts the lower frequency signal. The unipolar input impedance is not necessarily 50 ohms. Shorter unipolar usually has lower input impedance. An impedance transformer is printed on the ground for matching. FIG. 15 is a schematic diagram of the electrical characteristics of a curved monopole antenna (1500) according to an embodiment of the present invention. The bent monopole antenna (1 500) includes an LC trap circuit (1 505). The electrical characteristics of the LC trap circuit (1 505) include an inductor (1510) and a capacitor (1520) connected in parallel. As mentioned above, in the embodiment of a single inductor component, the capacitor and the inductor are provided by a single inductor component.

Description of the invention (23) (Please read the precautions on the back before filling this page) Inductor (1 605) is a spiral, which is usually a circular pattern with a decreasing radius. The printed inductor has less parasitic capacitance, so an extra capacitor is added to the LC trap circuit. The additional capacitor (capacitor (1 600)) may be an additional commercially available capacitor component, or as shown in FIG. 16, the capacitor (1 600) may be two opposite printed thin plates (1 600A) and ( 1 600B). Fig. 17 shows a coplanar bent monopole antenna (1 700) according to an embodiment of the invention. A ground plane (Π30) is provided. The ground plane (1730) is part of a circuit board that includes a radio frequency circuit configured to feed a signal to an antenna (1700). The antenna (1 700) is shown as an extension of the circuit board. The coplanar antenna (1700) includes first and second frequency elements separated by an LC notch circuit (1710). A base portion (1720) connects the coplanar antenna (1700) to a ground plane (1730). Printed by the Consumer Cooperative of the Intellectual Property Office of the Ministry of Economic Affairs. The choice of using a curved monopole antenna (1400) or a coplanar antenna (1700) will depend primarily on the orientation of a device in which the antenna is installed. Bent monopoles (1400) provide vertical dimensions, while coplanar antennas (1700) provide coplanar dimensions. These coplanar dimensions are good for devices with vertical orientation (such as the screen portion of a handheld computer, notebook computer, etc.) because the coplanar dimensions (direction) of the antenna can vertically polarize the signal sent from the antenna . For similar reasons, a horizontally oriented device (such as a motherboard of a notebook computer) facilitates the installation of a curved monopole antenna (1400). FIG. 18A shows one of the curved monopoles according to an embodiment of the present invention. layer. A first frequency element (1 840) has a non-rectangular base area. The paper size is applicable to the Chinese National Standard (CNS) A4 specification (210X297 mm). -26- Printed by the Intellectual Property Bureau of the Ministry of Economic Affairs and Consumer Cooperatives 565967 A7 ____ B7 5 Invention description (24) domain (1842) and back-end extension element (1850). The non-rectangular base area (1842) has a visibility of approximately 1.5 mm and is tapered such that the width becomes approximately 5 mm. The rear-end extension element (85o) includes a parallel extension (1 850A) and a vertical extension · U50B. A first layer part of an LC trap circuit (1 830A) includes a capacitor thin plate (1 832A), a Manhattan type inductor spiral (1 834), and a plated through hole (1 836) (for the first layer And shared by layer 2). The Manhattan-type inductor is printed on a substrate. The width of the inductor is approximately 1/8 mm, and the interval between the coils of the spiral is 1/8 mm. These dimensions are the same as all the specific dimensions described herein in accordance with the disclosure of the present invention, but we should understand that other dimensions can be substituted without departing from the scope of the present invention. In addition, circular, oval, triangular, or other shaped spirals can be used to form the inductor type. The shape of the spiral can be selected according to the ease of implementation of the spiral. For example, if a rectangular spiral is easier to draw in software or other tools used to implement the spiral, a rectangular spiral may be used. In another alternative embodiment, the inductor may be formed using any type of zigzag (non-specific orientation) lines or loops that are independent or printed (configured) on one or more layers of a substrate. Figure 18B illustrates a second layer of a curved monopole according to an embodiment of the invention. A second frequency element (821) also includes a rear extension element (1 822). These back-end extension elements are still used to adjust the correct frequencies at which these elements can most efficiently radiate RF signals. The height of the rear extension element (1 822) is between 3 and 4 mm, but the height is variable, especially when antennas with different overall heights are used. For example, this paper size is applicable to China National Standard (CNS) A4 specification (210X 297 mm) ------- *-Xu Yi ------ 1T ------ ^ (Please read the back first Please pay attention to this page and fill in this page) -27- 565967 A7 _B7 _ V. Description of the Invention (25) When the height of the overall antenna is 6 mm, the height of the rear extension element is 3-4 mm. For example, when the overall antenna height is 8 mm, the height of the rear extension element may be reduced to 0 mm. A second layer portion of an LC trap circuit (183B) includes a second capacitor thin plate (1832B) and a through hole (1836). In this embodiment, the first layer is disposed on one layer of a substrate, and the second layer is disposed on a second layer of the substrate. The first and second layers are connected to the through hole (1836). Fig. 18C is a composite view of the first and second layers of the bent monopoles shown in Figs. 18A and 18B connected to the through-hole (1836). The height of the bent monopole antenna is preferably 6 mm or 7.5 mm. The width of the taller antenna is 17 mm, while the width of a typical antenna is 25 mm. The height and width of the antenna can be selected according to packaging factors. The cover placed on the antenna will change the performance characteristics of the antenna. FIG. 19 shows a dual-band monopole antenna (1 900) having a ground plane (1910) coplanar with a radiator according to an embodiment of the present invention. The printed components (1 920), (1 930), (1 936), and (1942) are constructed in a manner similar to the corresponding components shown in FIG. 18C. The notch circuit (193) is connected to a second frequency element (1920), such as via a through hole (193). The size of the ground plane (1910) is approximately 15 mm x 30 ha. A transmission line (1 950) with a length of up to 9 mm is preferably printed next to a feed point (1960) immediately adjacent to the bipolar. The transmission line shown is a separate part of the non-rectangular base area (1942) connected to the monopole, but it is best to continuously print the transmission line as an identical part on a printed circuit board (PCB) (1970). Vertical parts ((1 942) and (1 950) combined paper sizes are applicable to China National Standard (CNS) A4 specifications (210X 297 cm)) (Please read the precautions on the back before filling this page) Printed by the Ministry of Intellectual Property Bureau P, printed by Industrial and Consumer Cooperatives -28- 565967 A7 ____________ B7 V. Description of Invention (26) (A single printed component). In this example, the PCB is L-shaped, the monopole is printed on the bottom of the L, and the ground plane is printed (please read the precautions on the back before filling this page) on the upper part of the L ( The L is reversed and reversed in FIG. 19) A transmission line (1950) is printed along a centerline of the ground plane (1910). The ground plane (1910) is printed on both sides of the PCB (1970), and the two sides are connected. It is best to use plated through holes (1 990) to make the connection between the two sides of the ground. Other connection methods can also be used alone or in conjunction with the plated through hole (for example, the ground plane is continuously printed on each edge (1 972), (1 974), and (1 976)). The function of a cut-out (1978) on one of the ground planes on the same side of the transmission line is to isolate the ground plane from the transmission line and one or more test points (1,980). The monopole configuration shown in Figure 19 is best suited for situations where the antenna can only be used in two dimensions (for example, inside an LCD monitor enclosure). The ground plane (1910) can be placed so that it is parallel to the LCD, while only about 6 mm of the monopole extends beyond the LCD. Printed by the Intellectual Property Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs. In the embodiments of the present invention, each embodiment can be fixed to a substrate, which usually contains a dielectric material as described herein. In one embodiment, the thickness of the substrate is about 1 mm, and the substrate is constructed with FR4 plates with 0.5 mm on both sides. Those skilled in the art will understand that various alterations and modifications of the preferred embodiment described above can be configured without departing from the spirit and scope of the present invention. For example, the present invention is obviously not limited to operation in the 2 · 4 GHz and 5 · 5 GHz frequency bands, but can be adjusted to operate at other signal frequencies. Then, in accordance with the disclosure of the present invention, this paper is again applicable to the China National Standard (CNS) A4 specification (210 × 297 mm) -29- 565967
