PLANAR MULTIBAND ANTENNA FOR MULTISTANDARD MOBILE HANDSET APPLICATIONS

A planar antenna for multiband operation is presented. The proposed microstrip-fed antenna includes a slotted ground plane, a T-shaped radiator, meandered and open circuit strips. A return loss of better than 10 dB is achieved at the frequency bands personal communication system (PCS) (1850-1990 MHz), UMTS (1920-2170 MHz), WiBro (2300-2390 MHz), WLAN + Bluetooth (2400-2480 MHz), WiMAX (2500-2690 MHz), and WiMAX (3400-3600 MHz). If a return loss of 6 dB is considered as a standard, the antenna can cover DCS (1710-1880 MHz). The proposed antenna occupies a small volume of 40 x 30 x 1.6 mm(3), which makes it attractive to the portable devices. The simulated and measured performance of the antenna confirms its multiband operation and omnidirectional radiation pattern. (C) 2011 Wiley Periodicals, Inc.
