Abstract:
A compact wideband microstrip antenna operating
over 5.45 GHz - 7.47 GHz bandwidth is reported. The design
uses double rectangular type annular-ring structured patch,
along with a circular arc at each corner acting as defected
metal structure (DMS) and two triangular-shaped defects in
the ground plane acting as defected ground structures (DGS).
The annular ring contributes to increase bandwidth of basic
microstrip antenna and further enhancement in bandwidth is
achieved by combination of both DMS and DGS. The design is
implemented on a RT/Duroid 5880 TM substrate. The overall
design size is 14 mm×18 mm. The maximum simulated gain of
the proposed antenna is 7.8 dBi. Hence, the proposed design is
found suitable for vehicle to vehicle communication in Intelligent
Transport System (ITS), WiMAX, WLAN, downlink of X-band
and satellite communication and other applications operating in
ultra wideband frequency range.
