Abstract :
An innovative wideband planar antenna is presented for mobile communications. The proposed planar antenna consists of four pairs of arc dipole, a balun for unbalance-balance transformation, and a conductor ground for gain enhancement. The prototypes of antenna is fabricated and measured. The measurement results show that the proposed antenna can achieve a bandwidth of 1.7-2.4 GHz or a relative bandwidth of 34.1% with the return loss greater than 10 dB, which can cover GSM/PCS/UMTS bands. In addition, the proposed antenna has a peak gain of 3.4-4.2 dBi throughout the entire operational bandwith with the radiation efficiency over 81%.
