Taper conformal omnidirectional double-frequency micro-strip antenna array

Abstract

The invention relates to a taper conformal omnidirectional double frequency micro-strip antenna array which is characterized in that a high-frequency micro-strip antenna array (2) and a low-frequency micro-strip antenna array (4) which are arranged up and down and are conformal with a taper carrier (1) are arranged around the cone surface of the taper carrier (1), wherein the high-frequency micro-strip antenna array (2) is near the conic node end of the taper carrier (1), and the low-frequency micro-strip antenna array (4) is arranged below the high-frequency micro-strip antenna array (2); the high-frequency micro-strip antenna array (2) consists of a plurality of high-frequency micro-strip antenna elements (6) in parallel feed connection, and the low-frequency micro-strip antenna array (4) consists of a plurality of low-frequency micro-strip antenna elements (11) in parallel feed connection. The invention realizes the conformality of a micro antenna and omnidirectional antenna beam coverage on the taper carrier as a geometric structure, and gaps are arranged at a radiationless side of each micro-strip antenna unit, and sizes of the micro-strip antenna element are reduced so as tomeet the demand of axis sizes of the taper carrier.

Description

technical field [0001] The invention relates to a microstrip antenna, in particular to a conical conformal omnidirectional dual-frequency microstrip antenna array conformal on the surface of a conical carrier. Background technique [0002] With the continuous development of modern communication and military technology, the electronic components required for airborne, spaceborne, missile-borne and various communication and telemetry remote control systems are developing rapidly in the direction of short, small, light, thin, and high reliability. In terms of performance, there is an urgent need for high-performance array antennas with good electromagnetic compatibility, less susceptible to electronic interference, small RCS (Radar Cross Section), and stealth / anti-stealth characteristics. Conformal microstrip antennas have a series of advantages such as low profile, light weight, small size, small radar cross section, and easy conformality, so they have been paid more and more ...

Problems solved by technology

However, how to achieve dual-frequency operation on the limited size of the surface of the missile carrier is a technical difficulty

There are two commonly used dual-frequency array implementation schemes. One is that the antenna unit itself is dual-frequency. The frequency band is difficult to control, and the design is difficult

Another solution is to design the antenna arrays of the two frequency bands separately, and then place the two arrays close together to achieve dual-frequency operation. The advantage of this solution is that the antenna design is simple, and only the design of a single array needs to be considered, but the disadvantage is that the antenna array Occupies a large area
