摘要：
A novel broadband bow-tie antenna with high-gain performance throughout the operating band is proposed and investigated in this article. This folded sectorial bow-tie antenna is fed by a ?-shaped strip balun, and the electromagnetic coupling feed mechanism is easy to optimize the impedance matching. The study of proposed antenna performance with different geometric parameters has been conducted. The final design is fabricated and measured, and the results exhibit a good impedance bandwidth of approximately 93.3% for VSWR2 ranging from 1.35 to 3.71GHz, stable gain of 8.43-10.02 dBi, and unidirectional radiation patterns over the whole operating band. Broadband coverage, stable high-gain performance, and the simple structure make this antenna an excellent candidate for wireless communication systems.
