Multiband meander antenna with a backed microstrip line

A novel multiband meander antenna with a backed microstrip line is proposed for GSM/DDCS/ISM and WiMAX triple-band operations. We have used meandering technique and U-shaped line to produce the GSM and DCS bands, respectively, and a backed microstrip line technique to produce the ISM and WiMAX band. Prototypes of the multiband antennas have been successfully implemented and good radiation characteristics in the operating frequency bands have been achieved. The effect of the backed microstrip line geometry on the return loss was also studied. (c) 2007 Wiley Periodicals, Inc.
