A novel printed directive antenna configuration

Abstract

A novel highly directive narrowband broadside antenna configuration based on TM13 mode of circular patch has been proposed here. The novelty in design is inspired by the concept of partially reflective surfaces. The antenna is simple fed by coaxial probe and have an overall ground plane diameter of 2λ with height less than 0.04λ. Side lobe levels are 21 dB down from the main lobe with the maximum gain of 11dbi at broadside direction.
