Abstract

The invention discloses a method for dynamically increasing the gain of a frequency reconfigurable microstrip antenna, comprising the following steps: 1. Constructing a frequency reconfigurable microstrip antenna, the microstrip antenna includes a reconfigurable antenna unit, and the reconfigurable antenna unit Including the main patch, parasitic patch and varactor diode, the parasitic patch is set outside the main patch and connected through the varactor diode; 2. Build a frequency reconfigurable gain board, the gain board includes a gain unit, and the gain unit includes double openings The resonant ring and the varactor diode, the varactor diode is arranged in one opening of the double-opened resonant ring; 3. Stand the gain plate directly above the microstrip antenna through the insulating column; 4. Change the capacitance of the varactor diode in the gain unit , to dynamically increase the gain of the microstrip antenna. Changing the capacitance value of the varactor diode can reconstruct the working frequency of the antenna, and can continuously adjust the working frequency, so as to widen the working frequency of the microstrip antenna. Through the gain board, the gain of the microstrip antenna is dynamically increased. Meet the use requirements.

Description

technical field [0001] The invention belongs to the field of wireless communication, in particular to a method for dynamically increasing the gain of a frequency reconfigurable microstrip antenna. Background technique [0002] In the field of wireless communication, low-cost antennas with broadband, high gain, miniaturization, and multiple functions are urgently needed. The planar microstrip antenna has the advantages of simple process, small size, light weight, low profile and diversified performance, and can work in dual-frequency or multi-frequency mode, and is easy to integrate with active devices and circuits, and has a wide range of applications. However, the current microstrip antenna has the disadvantages of not wide frequency band and low gain, and its application is limited. Contents of the invention [0003] The purpose of the present invention is to provide a method for dynamically increasing the gain of a frequency-reconfigurable microstrip antenna to meet th...
