Abstract :
In this paper, a Quasi-Yagi antenna with a simplified feeding network is proposed. The impedance bandwidth, radiation patterns and gain of the proposed antenna are studied by the Finite Difference Time Domain (FDTD) method. The simulated and measured results show that the accomplished bandwidth of the antenna can cover a frequency range from 4.64 GHz to 6.25 GHz, which involves the two WLAN bands of 5.15 GHz to 5.25 GHz and 5.75 GHz to 5.85 GHz. Within the frequency band, the radiation characteristic of the antenna exhibits a good performance, and the maximum gain is about 7.2 dB. The antenna is easy to integrate with the microwave circuits and other solid devices.
