Abstract

The invention relates to a frequency-reconfigurable microstrip antenna and a switch configuration method of the frequency- reconfigurable microstrip antenna. The antenna performs electricity feed in a side feeding mode and comprises a dielectric plate and an SMA connector, a semicircular radiating unit is arranged on the upper surface of the dielectric plate, and the inner ring of the semicircular radiating unit is perpendicularly provided with a microstrip antenna body; a metal patch grounding plate is arranged on the lower surface of the dielectric plate; the metal patch grounding plate is transversely provided with a first open groove and a second open groove which are parallel with each other; a patch radio frequency switch S9 is arranged in the middle of the first open groove in a spanning mode, and the inner center of the SMA connector is connected with a microstrip feeder line; the outer surface of the SMA connector is connected with the metal patch grounding plate. The smoothing function is integrated in the frequency-reconfigurable microstrip antenna, and therefore the antenna can be used for sensing the whole frequency band and then adjusting the band width of the frequency band to select an appropriate sub-band for work. Communication under the condition of various band widths and frequency bands can be met, and the frequency-reconfigurable microstrip antenna has good application value in wireless communication.

Description

technical field [0001] The invention relates to a frequency reconfigurable microstrip antenna and a switch configuration method thereof for cognitive radio applications. Background technique [0002] At present, the development of various wireless communication systems tends to be large-capacity, multi-functional, and ultra-broadband integrated solutions. As the front end of various wireless communication systems, the performance of the antenna is crucial to the function of the communication system. Therefore, the development of antennas also tends to be multi-frequency, broadband, and miniaturized. With the increasing complexity of wireless communication systems, transceiver devices must effectively handle several different frequency bands, the increase in the number of antennas, and issues such as space layout lead to higher hardware complexity. Reconfigurable antennas can be reconfigured in terms of antenna pattern, operating frequency, and polarization characteristics ...
