Novel Design and performance Analysis of Multiband Microstrip Antennas

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. The antennas became indispensible part in the front end of the wireless communication systems. The antennas operating at different frequencies are called multiband antennas. The design of compact multiband antennas with broad bandwidth is very difficult. The challenging issues in the design of these antennas are achieving broad bandwidth along with adequate gain.Advancements in the various new-fashioned technologies like 3G (1.92-1.98 GHz and 2.11 ¿ 2.17 GHz), 4G (2.3-2.4 GHz), Wi-Fi (2.4-2.485 GHz and 5.15-5.85 GHz) WLAN (2.4-2.48 GHz, 5.15-5.35 GHz and 5.725-5.825 GHz) and WiMAX (2.5-2.69 GHz, 3.4-3.69 GHz, 5.25-5.85 GHz) have been activated further research in the design and investigation of multiband antennas. The antennas working at the 3G, Wi-Fi, WLAN, and WiMAX are really important in numerous commercial applications.
