Abstract
In this paper dual wideband high gain circular shaped microstrip antenna with
modified ground plane is presented for wireless communication systems. The
overall dimension of the proposed antenna is 50 x 40 x 1.6 mm3. The
radiating element consists of circular shaped patch which is excited by
microstrip feed-line printed on FR4 epoxy substrate. The ground plane is on
the other side of the substrate having a rectangular ring shape to enhance
the peak gain of the antenna. The proposed antenna exhibits two wide
fractional bandwidths (based on ? -10 dB) of 61.1% (ranging from 2.0 to 3.8
GHz, centred at 2.88 GHz) and 53.37% (ranging from 5.48 to 9.6 GHz, centred
at 7.44 GHz). The measured peak gain achieved is 8.25 dBi at 8.76 GHz. The
measured impedance bandwidth and gain suffice all the commercial bands of
wireless systems such as 4G LTE band-40, Bluetooth, Wi-Fi, WLAN, WiMAX,
C-band, and Xband. The measured results are experimentally tested and
verified with simulated results. A reasonable agreement is found between
them.
