Abstract
In this paper a novel planar micro-strip antenna is presented for quad band applications. The antenna structure is composed of symmetrically step slotted (pruned) rectangular patch at the right and left edges with a U-slot etched inside the patch along with a partial ground to achieve multiband operation. The proposed antenna is simulated on an FR-4 substrate of dielectric constant of 4.3, loss tangent 0.02 and 50Ω microstrip feed line. The simulation and optimization results are carried out using CST software 2014. The antenna topology occupies an area of 23×22×1.5mm3. The antenna operates at four different resonant frequencies 2.5GHz (2.36GHz-2.70GHz), 5.1GHz (4.85GHz-5.33GHz), 9.95GHz (9.64GHz-10.31GHz) and 14.6GHz (13.83GHz-15.89GHz) which meet the requirements of the Wi-Max, WLAN, X-band and Kuband. The impedance bandwidths are 13.49%, 9.4%, 6.64% and 14.07% for the 2.5GHz, 5.1GHz, 9.95GHz and 14.6GHz bands respectively. The antenna shows good return loss, VSWR and radiation pattern characteristics in the desired frequency range.
