Abstract

The size of traditional microstrip antenna is too large for some handset applications, and the bandwidth of typical planar inverted-F antenna (PIFA) is not wide enough. In this paper a PIFA structure with slot ground has been developed, which provides wider bandwidth and higher gain but with minimized size. The proposed antenna structure provides seven times bandwidth and 1.1 dB higher gain compared with typical PIFA, and the size of radiate patch has been reduced at the same time. This structure is very suitable for radio frequency handset applications.
