Leaky wave antenna for wide range of beam scanning through broadside in dielectric image line environment

Leaky wave antenna for wide range of beam scanning through broadside in dielectric image line environment

In this letter, a broadband leaky wave antenna based on dielectric image line (DIL) is proposed in Ku‐band. An H‐shaped metal strip is used to mitigated the open stop band problem. A prototype is measured which exhibits an impedance bandwidth of 33.2% (11.3–15.8 GHz) and the beam scanning of 98° (−6...

description In this letter, a broadband leaky wave antenna based on dielectric image line (DIL) is proposed in Ku‐band. An H‐shaped metal strip is used to mitigated the open stop band problem. A prototype is measured which exhibits an impedance bandwidth of 33.2% (11.3–15.8 GHz) and the beam scanning of 98° (−60° to 38°) through broadside. The measured peak gain in the band is 15 dBi.
