Multiband Corrugated Plus Shaped Inverted half Cylindrical Dielectric Resonator Antenna for numerous wireless applications

A corrugated plus shaped inverted half cylindrical dielectric resonator (CDRA) antenna is analyzed for wireless applications. Proposed antenna targets IEEE 802.11p standard wireless access in vehicular environments (WAVE) allocated applications bands. Less contact base area to ground plane for inverted half cylindrical DRA & deployed corrugation plays an essential role for enhancement of the bandwidth and gain. In proposed antenna HE

This antenna attributes cover the multiband frequency responses, it has been operated at 4.5 GHz (4 - 5.5 GHz), 6.75 GHz (6.6 - 6.9 GHz), 7.9 GHz & 11.5 GHz (7.7- 11.8 GHz) resonant frequency respectively. 10.52 dBi peak gain achieved at 8.4 GHz frequency. All the operating band it offered has more than 6 dBi gain.
