Quad Band Printed Antenna for Wi-Fi, WLAN, C-band and WiMAX Applications

Design of simple and inexpensive multiband antennas covering different applications have been played prominent role in modern wireless communication systems and also attracted the researchers to do more research and investigation. Antennas became indispensible part in the front end of the wireless communication systems. Breakthrough in the developments of contemporary wireless communication systems has outspread the demand for a low profile, simple, inexpensive and versatile antennas operating at different modes. The quad band printed antenna for supporting Wi-Fi, WLAN, C-band and Wi-MAX applications is designed and analyzed in current article. This quad band antenna contains a slotted radiating patch on dielectric substrate and defected ground on opposite side. The quad band antenna operates at four distinct frequency bands of 2.41–2.58 GHz, 3.40–3.70 GHz, 3.94–4.62 GHz and 4.97–5.95 GHz respectively. It exhibits adequate return loss and gain over the operating bands. It is fed with microstrip line. The designed quad band antenna is fabricated and also taken measurements to examine its performance.
