Designing of Compact Spectacles Shaped Ultra-wide band Microstrip Patch antenna

Abstract

In this paper an antenna is designed for ultra-wideband for wireless applications. The antenna is resonating at 16 GHz frequency range. The proposed antenna is designed by using spectacles shaped defected patch i.e DMPS (Defected microstrip patch Structure) for particular feeding technique (microstrip line feed) is used. In this design antenna is fed by microstrip line feed with single port. In Microstrip Patch antenna, there are four types of feeding techniques, in which microstrip line and coaxial probe feeds are contacting schemes whereas proximity and aperture coupled feed are non-contacting schemes. In the Paper, we have designed the various parameters like bandwidth, return loss, S-Parameters, smith chart, radiation pattern, bandwidth, VSWR and resonant frequency an antenna and their effect. Finally simulation is done using design software HFSS(High Frequency Structure Simulator).
