In this paper, the effects of shorting pin on resonant frequency of the gap-coupled circular microstrip patch antennas is presented. The effects of location of shorting pin and variations of its diameter as well as the effect of variation of gap distance between adjacent edges of the feed patch and parasitic patch of gap-coupled circular microstrip patch antennas on the resonant frequency is simulated...
In this paper, we have simulated 2D photonic crystal (dielectric slab with regular cylindrical periodic lattice of air-gap) as substrate to enhance the electrical performance of the microstrip (rectangular or circular) patch antenna at THz/millimeter wave frequencies. The periodic structures designed to open up frequency bands within which the propagation of electromagnetic waves is forbidden irrespective...
The effect of multilayer, 2-D photonic band gap substrate on the performance of rectangular microstrip patch antenna at THz frequency is simulated. The radiation efficiency, gain and directivity for the proposed antennas are 93.28%, 10.46 dB and 10.76 dBi, respectively at 875 GHz. The 10 dB impedance bandwidth of the antenna is 36.67%, which is ultra-wide bandwidth. The simulation has been performed...
