In this study, a design, simulation, fabrication, and measurement of the TEM-TE ₁₁ mode converter antenna (MCA) like a pelican beak are investigated. The working frequency of the pelican beak-shaped MCA (PBMCA) is the frequency in the range of 3.9–4.6 GHz (700 MHz bandwidth). Due to increasing the antenna cross-section, the probability of the electrical breakdown dramatically reduces. Electrical breakdown may occur at very high power outputs of the electromagnetic sources. The power-handling capacity of the PBMCA is 829 MW, at the centre frequency. The antenna is simulated and measured at three frequencies. The simulation results are a good agreement with the measurement results.

像鹈鹕喙一样的TEM-TE ₁₁模式转换器天线

在这项研究中，研究了像鹈鹕喙一样的TEM-TE ₁₁模式转换天线（MCA）的设计，仿真，制造和测量 。鹈鹕喙形MCA（PBMCA）的工作频率是3.9–4.6 GHz（700 MHz带宽）范围内的频率。由于天线横截面的增加，电击穿的可能性大大降低。电击穿可能发生在电磁源的高功率输出处。在中心频率处，PBMCA的功率处理能力为829 MW。在三个频率下对天线进行仿真和测量。仿真结果与测量结果吻合良好。
