Abstract The antenna proposed in this study is a double‐branch radiator antenna. The radiator of this antenna is neither a conventional single‐branch radiator nor is it just a simple combination of 2 radiator branches. Moreover, a parallel resonance wideband feeding technology is used on the feed structure of the proposed antenna. The reference antenna in this study was a conventional single‐branch radiator antenna, which also uses the parallel resonance wideband feeding technology. A total of 3 resonant current modes are generated with the proposed antenna. The operating mechanisms of the 3 modes were analyzed in detail. The results showed that the impedance bandwidth was significantly enhanced with the simple modification. The impedance bandwidth reached 210 MHz (0.83‐1.04 GHz), which is 2 times that of the reference antenna and approximately 4 to 5 times that of a conventional planar inverted‐F antenna (PIFA).
