The plane antenna has the characteristics of small size, high gain, light weight, thin thickness, low cost, simple structure, easy manufacture, etc. The plane antenna is suitable for general UHF TVs and SHF satellite TVs and can be used for the communication of microwaves and radars in L, C and K wave bands.
Description
The present invention is a kind of TV and radar flat plane antenna.It adopts microstrip antenna structure, its architectural feature: make antenna radiation unit on dielectric substrate, another side is the metallic plate of ground connection.It has that volume is little, high, in light weight, the thin thickness of gain, cost is low, simple in structure and make characteristics such as easy.Be not only applicable to UHF common TV and SHF satellite television, and can be used for L, C, K band radar and microwave communication.
The most parabolic antennas that adopt of existing satellite television and radar antenna, not only volume is big for this traditional antenna, heavy, cost height but also adjust trouble.For this reason, the present invention proposes a kind of thin type flat plane antenna, and its basic comprising as shown in Figure 1.Below in conjunction with Fig. 1 description architecture feature.
In Fig. 1,2 is dielectric substrate.Can select baseplate materials such as tetrafluoroethene, polystyrene printed circuit board (PCB), glass, mica, beryllium oxide, quartz, polymethyl methacrylate, pottery and plastics for use.On dielectric substrate, make antenna radiation unit with methods such as photoetching, burn into evaporation, sputter, deposition, spraying, stickup, plated films.
The shape of antenna radiation unit 1 can be designed to different shapes such as rectangle, square, garden shape, annular, fan-shaped, bar shaped, profile of tooth, half garden shape, ellipse garden shape, triangle, city wall shape, square annular and polygon as required.The very thin thickness of dielectric substrate (less than wavelength).The another side of dielectric substrate can adopt with on identical method make the grounding electrode 3 of conduction.Antenna radiation unit 1 is with 4 to link to each other with feeder line by narrower little of width.
Also can on dielectric substrate, produce a plurality of antenna radiation units, for example on windowpane, make hundreds and thousands of antenna radiation units, with they series connection, parallel connection or connection in series-parallel feed with vacuum coating method (or plastics plated film).Though the gain of each antenna radiation unit is less than 1 decibel, hundreds and thousands of add up can obtain tens of decibels gain.Because its thickness only has several centimetres, therefore can make the planar array antenna of thin type high-gain.Embodiment below in conjunction with description of drawings different shape antenna radiation unit: embodiment 1, UHF common TV antenna

Also antenna radiation unit can be designed to garden shape, its diameter approximates λ
9/ 2 λ wherein
9Be the wavelength of electromagnetic wave in dielectric substrate, apparent, when channel not simultaneously, the size of antenna radiation unit also should change.
According to reception antenna and transmitting antenna principle of reciprocity, flat plane antenna also can be used for transmitting antenna.
Fig. 2 is K band satellite TV and radar planar array antenna.Be used to receive satellite television and the K band radar signal of 11.7～12.5GHz.Its structure be thickness be on 0.8 millimeter the polystyrene printed circuit board (PCB) 2 with the corroding method of taking pictures, simultaneously make 32 * 26 city wall shape antenna radiation units at it.The profile thing of antenna radiation unit is levied as shown in Figure 3, and each height H is 8.2 millimeters, and width L is 4.1 millimeters, and D is at a distance of 12.3 millimeters between each antenna radiation unit.32 antenna radiation units of every row, mutually series connection is that 1.2 millimeters city wall shaped microstrip links up and forms by a width W, the terminal of every row is connected to build-out resistor R.This flat plane antenna has 26 row, each row A point parallelly feeding.The another side of printed circuit board (PCB) is the metal foil electrode of ground connection.It is 620 millimeters that whole printed circuit board (PCB) is installed in length, and width is 560 millimeters, and thickness is on 25 millimeters the antenna frame, supports with the mast 4 of 40 millimeters of diameters.
Above-mentioned flat plane antenna has 832 antenna radiation units, and 8 kilograms of antenna weight gain 36 decibels.
Embodiment 3 C-band satellite televisions and radar planar array antenna
