Coplanar antenna capable of directionally radiating along surface of carrier

Abstract

The invention relates to a coplanar antenna capable of directionally radiating along the surface of a carrier, and belongs to the technical field of antennas. The coplanar antenna comprises a dielectric substrate, an active radiator patch, a director patch, a reflector patch, a metal short-circuit pin and a radio frequency cable socket, wherein the active radiator patch, the director patch and thereflector patch are all attached to one side (one side, facing outwards, of the surface of a carrier) of the dielectric substrate, the whole surface of the other side of the dielectric substrate is coated with copper, the radio frequency cable socket is welded to the side and located on the back face of the active radiator patch, the active radiator patch is fed from the bottom, and the feeding position is located in the center of the patch. According to the invention, the coplanar antenna capable of directionally radiating along the surface of the carrier can be embedded into the surface ofthe carrier to be designed to be coplanar with the carrier.

Description

technical field [0001] The invention belongs to the technical field of antennas, and in particular relates to a coplanar antenna with directional radiation along the surface of a carrier, which forms vertical polarization (perpendicular to the surface of the carrier) directional radiation in a tangential direction along the surface of the carrier. Background technique [0002] It is often necessary to install multiple antennas with different functions on a high-speed moving carrier, such as navigation, communication, radar, and altimetry antennas. At present, most of these antennas are exposed antennas, which will not only affect the aerodynamic performance of the carrier, but also cause conflicts in the assembly position, resulting in physical shielding and electromagnetic compatibility problems. Coplanar antennas have unique advantages in solving the above problems. [0003] The coplanar antenna can be coplanarly designed with complex carriers of various shapes, and becom...

Problems solved by technology

In the prior art, there is also the technology of using the microstrip antenna working on the main mode as a unit to form directional radiation technology, but the directional radiation antenna composed of the microstrip antenna working on the main mode has obvious beam upturning when the metal floor is large, and the gain in the horizontal plane lower

In recent years, units equivalent to magnetic current radiation have been applied to solve the above technical problems, but there are still problems of large size and lack of flexible design of reflectors, so a coplanar antenna that radiates directional along the surface of the carrier is proposed. Great practical application value
