PIFA and IFA Hybrid Antenna for the Data Communication Terminal
Abstract
In this paper, we designed and implemented a PIFA(Planer Inverted F Antenna) and IFA(Inverted F Antenna) hybrid antenna for the data communication terminal such as smart phone. Studied hybrid antenna has multi-band characteristics by the simultaneous operation both PIFA and IFA under a feeding structure. VSWR measurement of implemented antenna was satisfied 3:1 over GSM900/USPCS/WCDMA band. Measured average gains and efficiencies were -2.19~-3.63 dBi and 43.31~60.33 % for the GSM900 band, and -2.16~-10.67 dBi and 8.56~60.78 % for the USPCS/WCDMA band.
