Abstract

The invention discloses a three-frequency dual polarization cone conformal micro-strip antenna array. Three-frequency operation is achieved by vertically placing a single-frequency micro-strip antenna array and a dual-frequency micro-strip antenna array on the surface of a cone, and the antenna arrays evenly surround the surface of the cone to achieve omni-directional wave beam coverage. Each array is formed by connecting four micro-strip antenna units through micro-strip lines in a parallel feeding mode. Micro-strip antenna radial edges feed a single-frequency antenna unit, and micro-strip antenna non-radial edges feed a dual-frequency antenna unit. The size of patches is reduced by slotting the non-radial edges of the single-frequency antenna unit, and a patch unit works for linear polarization. Dual frequency is achieved by slotting the radial edges of the dual-frequency antenna unit, low frequency is circular polarization, and high frequency is linear polarization. Micro-strip media used for processing antennas are flexible special media. According to the three-frequency dual polarization cone conformal micro-strip antenna array, the three-frequency dual polarization work requirement can be achieved on the surfaces of limited carriers, and omni-directional coverage of wave beams can be achieved.

Description

technical field [0001] The invention relates to a microstrip antenna array conformal to the surface of a conical carrier, in particular to a triple-frequency dual-polarization conical conformal microstrip antenna array. Background technique [0002] With the continuous development of modern communications and military, the electronic components required by airborne, spaceborne and various communication and telemetry remote control systems are developing rapidly in the direction of short, small, light, thin, high reliability and high speed. 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, and easy to achieve conformality, so they have been paid more and more attention in recent y...
