Abstract

Radiation characteristics of an inductive loaded patch phased array antenna (PAA) are compared to those of a conventional patch PAA. The performance of an inductive loaded patch PAA is significantly improved compared to that of a conventional patch PAA because the mutual coupling between the adjacent inductive loaded patch antennas is very small compared to that between the adjacent conventional patch antennas. The radiation characteristics of an inductive loaded patch PAA show superior performance such as low variations of the main beam gain and sidelobe level over the variation of the main beam direction.
