Abstract
A modified leaky-wave antenna based on periodic patch is presented in this paper. A new technique introducing coupled lines with via holes is proposed to overcome the open stop band problem in periodically loaded leaky wave array antenna designs. A wideband bandwidth is obtained along with high antenna gain of about 15 dBi for the proposed leaky wave antenna. This periodic leaky wave antenna loaded with periodic symmetric patches is also providing frequency scanning from -40 deg to 40 deg. through broadside.
