Coaxial feed dual wideband dual polarized stacked microstrip patch antenna for S and C band communication

This article presents the stacked arrangement of a truncated ellipse act as driven patch loaded by a rectangular slot and a circular patch which is partially truncated and loaded by another rectangular slot. This structural arrangement gives rise a wide impedance bandwidth (-10dB) in two bands 3.14-4.13GHz (27.2%) with linear polarization in S band and 6.16-7.01GHz (12.8%) with circular polarization in C band. The peak gain value in both the bands are 7.72dBi and 6.64dBi respectively. This antenna is found useful for communication in S and C band respectively.
