Design of a Novel Wideband Planar Inverted-F Antenna for Mobile Applications
In order to meet the tendency of miniaturization, broadband, amalgamation of multi-systems for mobile communication terminals, a novel practical wideband internal planar inverted-F antenna (PIFA) is proposed in this paper. The presented antenna exhibits a very wide bandwidth ranging from 1.67 to 4.05 GHz with the definition of -10 dB return loss. The relative bandwidth is larger than those of the existing antennas with similar structures, and comes up to 83％, which makes the designed antenna cover the frequency bands of DCS1800, PCS1900, WCDMA, UMTS, WiBro, WLAN and DMB simultaneously. It is also found that the radiation patterns in free space, gain and efficiency of the proposed antenna satisfy the needs of wireless communication terminals. Moreover, the antenna with the optimized parameters was fabricated and measured. Good agreement between the measurement and simulation results can be observed.
