Abstract
This paper demonstrates the comparative study of Rectangular and Circular microstrip patch antenna. The center frequency 21.5 GHz is chosen as the resonating frequency with variety of wireless applications under K-band whose frequency range is defined by the IEEE as 18 GHz to 26 GHz [4]. HFSS12 is being used as the software to design and study the comparison between the performance of two antennas. The antennas are designed on a FR4 epoxy substrate having a relative permittivity of 4.4. To operate all over the frequency range of K-band the log periodic implementation of the antenna is done by the frequency scaling method using a scaling factor ‘τ’. The return loss, VSWR, directivity and gain of the proposed antenna are analyzed from the simulation results.
