Abstract :
A technique consisting in designing the groundplane of a handset antenna is presented. The technique is applied to PIFA antennas to show how the bandwidth can be enhanced. Particularly, a dual-band PIFA operating at GSM900 MHz and GSM1800 MHz is expanded up to quad-band and hexa-band operation by means of groundplane design. Results for antenna efficiency show that the proposed technique can be applied to design multi-band antennas for handset phones.
