摘要

我们分析了一种由2 × 1威尔金森功率合成器馈电的微带贴片天线在300 GHz下的性能。仿真结果表明，与单口馈电相比，采用威尔金森功率合成器馈电可获得2.54 dB的总辐射功率增益。结果进一步表明，该组合器在输入端口之间提供了-21.5 dB的良好隔离。此外，xz和yz平面的+z (θ =0)方向的峰值功率增加了4.8 dB。

Performance Analysis of a Wilkinson Power Combiner-Fed Patch Antenna for 300-GHz Arrayed Photomixers

We analyzed the performance of a microstrip patch antenna fed by a 2 by 1 Wilkinson power combiner at 300 GHz. Simulation results show that a 2.54 dB gain in total radiated power can be achieved when the Wilkinson power combiner is used to feed the antenna compared to a single-port power feed. Results further show that the combiner provides a good isolation of -21.5 dB between the input ports. Additionally, the peak power in the +z (theta =0) direction for both xz and yz planes increases by 4.8 dB.
