摘要：

A quasi-Yagi microstrip patch antenna with four directors and truncated ground plane has been designed and fabricated to have an ultra-wide bandwidth, high gain, low return loss and better directivity with center frequency at 3.40 GHz. After optimization, the proposed antenna yields an ultra-wide bandwidth of 1.20 GHz with lower and upper cutoff frequencies at 3.12 GHz and 4.32 GHz, respectively. High gain of 5.25 dB, return loss of -28 dB and directivity of 6.28 dB are obtained at resonance frequency of 3.40 GHz. The measured results of fabricated antenna have shown excellent agreement with the simulation results providing bandwidth of 1.34 GHz with lower and upper cutoff frequencies at 3.04 GHz and 4.38 GHz, respectively. The antenna gain of 5.33 dB, return loss of -44 dB are obtained at resonance frequency of 3.36 GHz. The dimension of the antenna is only of 65 mm x 45 mm ensuring compact in size. © The Author(s).
