Abstract:

A novel dual band microstrip planar antenna array with patch element schemed by using insetfed feed technology is proposed. This feed structure is equivalent to loading a reactance on the microstrip patch. Through adjusting the length of the feeding line, the microstrip antenna obtains two zero points and realizes dual band. Based on this patch element and parallel network, a planar 4×4 dual band microstrip array is fabricated. The experiment and simulation results have a good agreement. The dual band is at 32.5 GHz and 35.7 GHz. The gain of the antenna array is 16.25 dB and the radiant efficiency is 82%.
