TEM-TE11 mode converter antenna like a pelican beak

摘要

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.
