Abstract

The invention relates to a levorotatory and dextrorotatory integrated design microstrip antenna, which comprises a dielectric substrate, a reflecting plate and a feed probe, and is characterized in that a rectangular main patch and four parasitic patches are arranged on the dielectric substrate, each parasitic patch and a corresponding corner are arranged at intervals, PIN diodes are arranged in the intervals, the PIN diodes are connected with a direct current bias circuit, two parasitic patches on a group of opposite angles of a rectangular main patch are defined as a group of circularly polarized patches, the two groups of circularly polarized patches respectively form a left-handed circularly polarized patch and a right-handed circularly polarized patch, and the current direction of a PIN diode between the parasitic patch in the left-handed circularly polarized patch and a corresponding corner faces the feed probe. The current direction of the PIN diode between the parasitic patch in the right-handed circularly polarized patch and the corresponding corner is opposite to the feed probe. The microstrip antenna effectively solves the technical problems of inconvenience in use and slow conversion when a worker operates the microstrip antenna to receive and transmit circularly polarized waves in the prior art.

Description

technical field [0001] The invention relates to a left-handed right-handed integrated design microstrip antenna. Background technique [0002] The microstrip antenna is a new type of antenna that has been gradually developed in the past 30 years. Its most basic structure is to add a metal patch on the dielectric substrate with a grounded metal surface. Through a certain feeding method, the patch and the grounded metal surface The radio frequency electromagnetic field is excited in the dielectric region between the patch, and the field radiates outward through the gap formed by the edge of the patch and the ground plane. Compared with commonly used microwave antennas, microstrip antennas have the following advantages: 1) small size, light weight, low profile, and can be conformal to carriers (such as aircraft); 2) microstrip units with diverse electrical properties and different designs , its maximum radiation direction can be adjusted from side-fire to end-fire; 3) It can b...
