Design and Implementation of L-band triple-frequency series-fed microstrip antenna

A L-band multi frequency series fed microstrip antenna based on satellite positioning is proposed. The antenna was fed by three layers at the same position, and a metal through hole was set in the center of the antenna to adjust the impedance matching of each layer. At the same time, a 3dB coupler w...

Summary:A L-band multi frequency series fed microstrip antenna based on satellite positioning is proposed. The antenna was fed by three layers at the same position, and a metal through hole was set in the center of the antenna to adjust the impedance matching of each layer. At the same time, a 3dB coupler was introduced to realize circular polarization. Because the three layers are fed by the same position, the left-handed and right-handed switching could be realized. Finally, the simulation results show that the standing wave is in the desired position. When the standing wave in the frequency band is less than 1.8 and the beam width reaches 70°, the gain meets the transmission requirements.
