Abstract
The invention discloses a microstrip array antenna of a portable ground surveillance radar. The microstrip array antenna includes an antenna plate and a mounting plate; the antenna plate is installed at the center of the mounting plate; one surface of the antenna plate is provided with copper foil, and the other surface of the antenna plate is provided with a tin plated layer; the surface of the antenna plate, which is provided with the tin plated layer, is provided with 126 rectangular antennas; every four rectangular antennas in the same square area form small array antennas, and signal ports of the four rectangular antennas are connected with one another; every four small array antennas in the same square area form a large array antenna, and signal ports of the four small array antennas are connected with one another; and signal ports of two large array antennas are connected with one another. According to the microstrip array antenna of the portable ground surveillance radar of the invention, a plurality of rectangular antennas are combined together so as to form the microstrip array antenna. The microstrip array antenna is of a special structure, so that the microstrip array antenna has the advantages of high gain and reasonable size.
Description
Technical field
The present invention relates to a kind of micro-strip array antenna, particularly relate to a kind of micro-strip array antenna of portable type ground surveillance radar.
Background technology
The external continuous wave standard Radar Products having occurred various ways, and in traffic monitoring, naval vessel is crashproof, meteorological observation, and high field of testing the speed is applied.The F6 type radar velocity measurement capturing system that current European most countries all adopts German ROBOT company to produce, occupation rate of market is more than 60%.The BR24 continuous wave frequency X-band radar that Navico company of Norway produces, non-blind area, close-up images is incomparably clear, without magnetron, can launch by button, the healthy fanout free region of ultralow Microwave Radiation On Human body, and cheaper, can be used as the desired Safety navigational radar of medium and small-scale vessel bay and complicated cruiseway.Britain succeeds in developing continuous wave and to navigate serial radar, microprocessing is applied in tracking control unit, function is improved a lot, and improves the ability of clutter reduction interference simultaneously.The velocity radar that Weibel company of Denmark produces, adopts all solid-state transmitter, low noise zero intermediate frequency reciver and plane microstrip antenna array, very representative.
The microstrip antenna of traditional ground surveillance radar also exists that gain is low, orientation minor level and the high and problem that the size of antenna is large of pitching minor level.
Summary of the invention
Object of the present invention is just to provide a kind of high-gain to solve the problem and the micro-strip array antenna of the portable type ground surveillance radar of Sizes.
In order to achieve the above object, present invention employs following technical scheme:
A kind of micro-strip array antenna of portable type ground surveillance radar, comprise antenna plate and mounting panel, described antenna plate is arranged on the center of described mounting panel, the one side of described antenna plate is provided with Copper Foil, another side is provided with tin coating, the one side being provided with tin coating of described antenna plate is provided with 126 squaerial, the length of described squaerial is 13mm, width is 8mm, between described squaerial on its long side direction interval 13mm, interval 16mm in its broadside, every four described squaerial in same square area form a small array antenna, the signal port of four described squaerial is connected to each other, every four described small array antennas in same square area form a large-sized array array antenna, the signal port of four described small array antennas is connected to each other, the signal port of two described large-sized array array antennas is connected to each other.
Particularly, described antenna plate is provided with multiple steam vent, described steam vent is arranged on the interval between described small array antenna, and the diameter of described steam vent is 1mm.
Particularly, four angles of described antenna plate are fillet, and the radius of fillet is 5mm.
As preferably, described antenna plate is polyfluortetraethylene plate, and the thickness of described antenna plate is 0.76mm.
Beneficial effect of the present invention is:
