Abstract

The invention provides a parasitic unit loaded high-gain dual-frequency microstrip antenna. The antenna mainly comprises a metal floor layer, a dielectric substrate layer, a rectangular radiation patch, a feeder line and a parasitic unit, the metal floor layer is the bottommost layer, the dielectric substrate layer covers the metal floor layer, the rectangular radiation patch is located on the upper surface of the dielectric substrate layer, the microstrip feeder is arranged on one side of the upper surface of the dielectric substrate layer and connected with the rectangular radiation patch, and the parasitic units are arranged on the two sides of the feeder. The upper half part of the rectangular radiation patch is composed of a plurality of four-leaf clover-shaped arc-shaped patterns which are uniformly distributed; the structure of the parasitic unit is obtained by respectively setting a group of opposite sides of a square into a shape like a Chinese character 'ao'. According to the antenna, double-frequency resonance frequency points can be realized in an S wave band with a relatively small structure, the gain of the microstrip antenna is improved, and the practicability of the microstrip antenna is enhanced.

Description

technical field [0001] The present application relates to the technical field of antennas, in particular to a high-gain dual-band microstrip antenna loaded with parasitic elements. Background technique [0002] With the development of electronic technology in the fields of mobile communication, aerospace and other fields, all kinds of electronic equipment are developing towards the direction of miniaturization. Microstrip antennas are widely used in the fields of mobile communication, aerospace, electronic countermeasures and radar. Microstrip antennas have attracted widespread attention due to their small size, low profile, and easy integration with large-scale integrated circuits. However, its own structural characteristics lead to the disadvantages of low gain and poor directivity of the microstrip antenna. Moreover, due to the rapid development of antenna wireless systems, the original frequency bands are becoming more and more crowded. In order to increase the number...
