提出了一种适用于微波、毫米和亚毫米波段的宽带端射平面电路天线。我们串联了两个不同长度的偶极子，以加宽带宽。使用两个印刷导向器和一个截断地平面来实现高自前向后(F/B)增益比。馈电给天线驱动器的平行带状线直接连接到微带，而不需要中间级。这种简单的天线设计很容易集成到微带电路中。在这封信中，我们重点设计了一种Ku波段的天线，带宽为7 GHz，F/B增益比为RSI 18dB。天线的设计和分析使用了严格的电磁模拟，并通过测量罗杰RO 4350印刷电路板上的天线的波束方向图和回波损耗来实验验证天线的性能。最后，我们给出了该天线在亚毫米探测器领域的两个独特的应用实例。
We present a broadband endfire planar circuit antenna that is suitable for applications in microwave, millimeter (mm), and submillimeter (sub-mm) wavelengths. We have cascaded two dipoles of different lengths in series to broaden the bandwidth. Two printed directors and a truncated ground plane are used to achieve high front-to-back (F/B) gain ratio. The parallel stripline feeding the antenna's drivers is connected directly to microstrip without an intermediate stage. This simple antenna design is easily integrated into microstrip circuits. In this letter, we focus on the design of a Ku-band antenna with 7 GHz bandwidth and F/B gain ratio of rsi 18 dB. Design and analysis of the antenna were performed using rigorous electromagnetic simulations, and we experimentally validated the performance of the antenna by measuring the beam patterns and return loss of an antenna fabricated on a Roger RO 4350 printed circuit board. Finally, we present two unique example applications of the antenna in the sub-mm detectors area.
