The wideband characteristics of plate antenna with elliptical cross section

摘要

A plate antenna with elliptical cross section and ellipticity ratio is studied. The return loss of the proposed antenna and conventional antennas is investigated using the simulation package CST MW Studio ver. 3.2 and fabricated antennas. The effects of ellipticity ratio on the radiation pattern and reflection coefficients are described. The given structure can handle the average power of several hundreds of watts. The simulated results of this antenna are obtained for various values of the ellipticity ratio of elliptical cross section loaded at the input port.
