Abstract

A frequency reconfigurable sensing patch antenna include microstrip feeder, a dielectric substrate, a radiating sheet and a ground plane, wherein the microstrip feed line is connected with the radiating sheet, the microstrip feed line and the radiating sheet are all stuck on the front side of the dielectric substrate, the ground plane is stuck on the back side of the dielectric substrate, and theground plane and the microstrip feed line are located at the same end of the dielectric substrate; A first branch and a second branch are respectively arranged on the two sides of the radiation sheet,and the first branch and the second branch are respectively provided with a first capacitor and a second capacitor at the connection with the radiation sheet; The first branch and the second branch are respectively provided with a first diode and a second diode. The antenna of the invention has the advantages that the antenna is a patch structure, the volume is small, the structure is simple andreasonable, and the antenna frequency is changed by using the on or off states of the first diode and the second diode, thereby realizing the reconfigurable antenna frequency.

Description

technical field [0001] The invention relates to the technical field of optical communication antennas, in particular to a frequency reconfigurable sensing patch antenna. Background technique [0002] In recent years, with the development of wireless communication systems in the direction of high integration and multi-functionality, antennas, as the key components for receiving or sending signals in wireless communication systems, have gradually become a research hotspot in the field of antennas for their multi-functionality and tunability. Due to the above characteristics, reconfigurable antennas have gradually shown great application potential. Its excellent electrical characteristics, such as frequency tunable, polarization or pattern reconfigurable, etc., can well meet the requirements of highly integrated antennas. Multifunctional wireless communication system needs. [0003] In recent years, scholars at home and abroad have proposed a variety of frequency reconfigurabl...
