INSTRUCTIONS: [Fx Ming's technical field] In particular, an extremely miniaturized flat panel invention relates to an antenna line structure. [Prior Art] At present, the satellite satellite guide (four) system has also quickly set off a wave, and in addition to the car-mounted audio and video system combined with the vehicle-mounted type, it has also developed a variety of Gps products such as _, 'ebook, mobile phone type, etc., where the car == too Portable car milk. For vehicles, there is no original equipment. s 2: For the main reason, choosing a portable GPS is indeed a good choice. * In addition to the price and strength, the portable miscellaneous allows users to bring a T-car. System, even if you can use it in the future. f GPS and PM, N〇teb〇〇k, mobile phone type and other electronic products ^In the starting material 1 will be in the electronic u ♦ metal sheet 2A, ground metal sheet 3A and signal feed body 4A. The base of this kind of antenna is made of high-density |<gate" electric hanging number (8~150) of Tao Jing made GPS circle ° "anti-antenna, resonant frequency is 1575. 42 ΜΗΖ. In recent years due to PDA and mobile phone When the volume is more integrated into the PDA and the mobile phone, the joint venture deducts the milk 糸h Τ^ to the existing antenna (as shown in the first figure), and the female yin is in the PDA virtual hand; the meat is jr-α Λ, ^ /, in the money 邛Moreover, such a circularly polarized flat-panel antenna is difficult to reduce the volume because the volume of the substrate is reduced: the area of the radiant metal 2 目 on the surface of the substrate is also the value of 16' After the area is reduced, the spectral frequency of the antenna is 200832809 19_Z. Although the antenna can be installed inside the small body-based rain-fed mobile phone, it cannot receive satellite signals. Therefore, such as = polarized planar antenna area and volume, It is a green problem to be solved by the present invention. [Summary of the Invention] Material:: The main purpose of the invention is that the side of the antenna is provided with a drop-off ίο% = the permittivity of a circularly polarized planar antenna having a dielectric constant. Still maintain the original resonant frequency and circle The special feature is:: 2 target 'The circularly polarized planar antenna structure of the present invention, the main piece is extended with a plurality of down-converted metal pieces on the side of the paste-two:: the side of the down-converted metal substrate is made to make a single side The upper cow = cymbal is placed at an oblique angle with the down-converted metal piece on the opposite side. When the product is to reduce the resonance frequency, the position of the down-regulated metal piece can be adjusted: the area added by the ΊΓ! frequency metal piece It shall not be larger than the area of the side of the substrate, or may increase the length of the down-converted metal sheet. [Embodiment] The technical content and detailed description of the relevant Luming's "Let's match the figure and the second picture" The first type of planar antenna of the invention has the appearance of two structures/knife solution diagrams as shown in the figure: the disclosed in the drawings is a miniaturized circularly polarized planar antenna structure including a metal piece 2 and a grounding The metal piece 3 and the signal feeding body 4. The antenna structure used in the handheld milk satellite navigation system can be built into a small size as described above. The base 1 of the above k is a cube and is high dielectric. Constant 200832809 (8~150) Made of ceramic, the upper surface has a groove ι3 and a perforation 11 of the bottom 1. The radiant metal piece 2 is a cubic sheet for attaching to the groove 13 on the surface of the substrate 1 and being opened thereon. Corresponding to the above-mentioned perforation ^ 21, and the radiation metal sheet 2 has four corners, and the truncated angle 22 of any two oblique diagonal angles is formed by a right-handed or left-handed circularly polarized panel antenna. Wherein, the truncated angle 22 on the radiating metal piece 2 is the upper right corresponding to the lower left side. Therefore, it belongs to the right-handed circularly polarized panel antenna. Please also refer to the fourth figure, the grounding metal piece 3 is a cubic sheet. There is a sheet 31 which is connected to the bottom of the substrate!, the sheet 31 has a through-hole (four) having an inner diameter larger than the perforation n, and a plurality of strip-shaped lower-frequency metal sheets extending on the four sides of the sheet. 33. The frequency reducing sheet 33 is attached to the side surface 12 of the substrate j such that the single side surface of the down-converting metal sheet 33 and the opposite side metal sheet of the opposite side surface 12' are disposed diagonally. In the figure, the down-converted metal piece 33 is used to reduce the resonant frequency of the antenna. When the volume of the base 1 of the antenna is reduced, the relative radiation is reduced in area, and the resonant frequency of the antenna is increased, so that the frequency is reduced. Meng is a piece 33 to restore the antenna resonance frequency to the desired frequency band. The signal feeding body 4 is a T-shaped body having a column or body 41 thereon, and the body 41 has a semicircular end at one end, and passes through the perforation in the body 41 of the mountain body of the shovel body. The side of the side and the through hole, the semi-circular end 42 of the '4-11' is electrically connected to the radiating metal piece 2, and the light is incident on the sub-piece 2, and the signal feeding body 4 forms a signal feed. Entry point. The design of the metal sheet 33 allows the antenna of the same material to be reduced in size (10 to 50%) and can be built into the hand-held electronic device of the current light, thin, short and small 200832809. : 参 =:,五图' is the flat antenna of the present invention, and the side view is not 0. As shown in the figure: in this figure, the truncated angle 22 of the radiant metal piece 2 of the flat plate is the upper right side of the library/lower Μ ί ^ zt ^ ^ ^ , and the lower part of the work is only the grounding gold S is extended: The down-converted metal piece 33 is set to the left side of the side surface 2, and the receiving and transmitting electric wave is a right-side circularly polarized panel antenna of the right-handed circularly polarized wave. ^ When the antenna needs to reduce the spectral frequency, the area of the (four) 19 Γ of the down-converted metal piece 33 1 can be increased to be no larger than the base of the substrate = Γί if the area of the down-cut metal piece 33 is larger than the basic. 々 Side-half area, will seriously affect the radiation gain of the antenna. Please refer to the sixth and seventh figures, which is the intention of the present invention.
