A Meander Antenna with Reconfigurable Polarization for Wireless Communication

Microstrip antennas are most widely used for wireless communication due to its properties like low cost, low profile, smaller in dimension and easy to fabricate and conformity. There are various shapes of antenna like rectangle, square, circle, triangle, dipole, meander etc. In this paper, comparison of rectangular, square, circular and meander patch microstrip antenna are done using HFSS software and meander is found to be the most effective. So meander antenna is used to achieve polarization reconfigurability at operating frequency of 2.4GHz. This polarization reconfigurable meander antenna works on the principle of reconfigurability where same antenna can be used for multiple applications in wireless communication. The meander antenna is fabricated on FR-4 substrate with r=4.4 and thickness of 1.6mm. The simulation of all the antennas are carried out using HFSS software and measurement is done using Rohde & Schwarz ZVH8 Vector Network Analyzer.
