Equilateral Triangular Micro strip Patch Antenna Using Different Substrates

A B S T R A C T The triangular geometry of microstrip antenna is one of the most common shapes having a wide range of wireless application ranging from circuit element to wireless antennas .The proposed equilateral triangular microstrip patch antenna is designed by using different substrates of different permittivity . Proposed paper gives an idea about bandwidth changes with change of substrate material.This antenna designed on Ansoft HFSS designer software, impedance bandwidth ,VSWR ,return losses & smith charts are observed and experimentally studied .Details of simulated results are presented and discussed. From results we concluded that proposed equilateral triangular patch antenna with co-axial probe feed gives better performance with substrate whose permittivity is 2.2( Rogers RT/duriod 5880(TM)).Which can be used in C-band operation .
