Abstract

Mathematical models are developed for planar symmetric slot antennas (SAs) with constant slot width using a tensor Green function that takes into account both principal and cross-polarization components in the far-field zone. It is shown that such models can be employed in the study of the electrodynamic properties of SAs with different configurations of slots (linear, exponentially increasing, etc.). The mathematical models are used to analyze the effect of geometrical sizes of the slots in the SAs under study on the radiation patterns (RPs). It is shown that the calculated RPs are in good agreement with the experimental results that makes it possible to reveal applicability limits of the proposed mathematical models. The SAs are studied in the microwave range at a central frequency of 10 GHz.
