Performance Analysis of Rectangular Patch Antenna for Different Substrate Heights
Height of the dielectric substrate material for a microstrip patch antenna is utterly important in terms of controlling bandwidth as well as surface wave. In this paper, the authors have presented a comparative study of effect of height in the performance parameters of rectangular shaped microstrip patch antenna. The antennas were simulated for purpose of the application of wireless LAN for resonance frequency 2.45GHz. Five antennas with different heights were designed using same dielectric substrate material with relative permittivity of 2.84 for the analysis of their performances. Coaxial probe-feed methods are used for feeding techniques.
