Dual Polarized Wideband Stacked Microstrip Antenna for S and C Band. Comparison of Radiation Performance of Dual Wideband Dual Polarized Stacked Patch Antenna for Wireless Communication

      Аннотация: In this volume the radiation performance of a coaxial feed dual wideband dual polarized stacked microstrip patch antenna for S and C band wireless communication using electromagnetic simulation tool IE3D (Integral Equation Three-Dimensional) and CST-MWS (Computer Simulation Technology Microwave Studio) is offered and discussed. The attempt is made to compare the antenna parameters such gain, impedance bandwidth and radiation pattern from both the Electromagnetic Software. Theoretical analysis of the stacked microstrip patch antenna is discussed and a portion of the well-known and generally utilized antenna analysis techniques and their highlights is also included. A prototype antenna is fabricated and its experimental results in compared with simulation results is also presented to validate the offered design. The structural arrangement gives rise a wide impedance bandwidth 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 respectively. It is recommended that IE3D is suitable if the ground and substrate size has no size constrain, however for finite size geometry configuration CST is a better choice.
