Design of Quad-BandAntenna for Wireless Communications

In this paper, the authors explain the design of multi-band microstrip antenna for GSM 900MHz, GSM 1800MHz,ISM 2.4GHz and WiMax 3.5GHz frequencies. The multi-band operation is achieved by etching rectangular slots on the ground plane of a Microstrip antenna. The simulation is performed with commercial electromagnetic software IE3D, using FR4 substrate. To demonstrate the effect of substrate parameters on the dimension of the antenna structure and multi-resonant operation, simulations are carried out with TMM10i and RO 4350 substrates. Antenna parameters are tabulated and compared for all the substrates. Antenna with RO4350 substrate performance is found to be better compared to other substrates considered.
