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...

Zusammenfassung:	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.
