Effect of Variable Thickness for Different Substrates on Rectangular Patch Antenna at 3 GHz

Amish Kumar Jha, Bharti Gupta

Abstract


The microstrip patch antenna is one of the most preferred
antenna structure for low cost and compact design wireless
system and RF application. In this paper, various design are suggested and analysed for different height of different substrates for rectangular patch antenna (RPA) operating at 3 GHz as centre frequency.
Using transmission-line model, analysis was done for the
behaviour of the antenna for different types of substrates, modified thickness, patch geometries and shifted feeding point. This design of RPA is made to several dielectric materials for different thickness
and the selection is based upon which material gives a better antenna performance with reduced surface wave loss. The result shows that Polyguide and RT Duroid 5880 for the thickness of 2.7 mm are the best materials for proposed design to achieve an enhanced Bandwidth
(BW) and better gain with lower value of VSWR. The characteristic of the patch antenna are analysed by the MOM using Feko EM solution
software version 6.0.
