摘要：

In this communication, we consider the effect of the thickness of the plate where slots are cut into, with reference to the design of a radial line slot array antenna. We show that the zero-thickness approximation results in a significant lack of accuracy even though the slot thickness is of the order of one-thirtieth of the wavelength. Then, we investigate and compare the accuracy and the efficiency of various approximate numerical techniques that can be conveniently employed in the full-wave analysis and optimization process of the antenna.
