Abstract
This paper is a comparative study of a rectangular microstrip patch antenna and a rectangular slotted reconfigurable microstrip patch antenna with pin diode. Antenna 1 has rectangular patch and Antenna 2 has a slot and a pin diode between slotted areas of the rectangular patch. The analysis is based on the antenna parameters such as return loss, VSWR, gain, directivity and radiation pattern and the operating frequency. As per IEEE standard, the designed antennas are applicable for k and Ka band application. The design and simulation has been done by using Ansoft HFSS software with substrate FR4_epoxy, which has dielectric constant 4.4 and tangent loss 0.02. The analysis shows that the values of antenna parameters change with the change in the geometry of the patch such as introducing slots and pin diode. The designed antenna has the operating frequencies of 19.35 GHz, 19.94 GHz, 27.04 GHz and 28.22 GHz and return loss of -27.85 dB, -23.26 dB, -33.05 dB, -25.86 dB and stable radiation pattern, omnidirectional and circular polarization at these operating frequencies.
