High Scanning Rate Leaky‐Wave Antenna Using Mixed Cross‐Coupling Sections
ABSTRACT A high scanning rate microstrip leaky‐wave antenna (LWA) cascaded by 10 mixed cross‐coupling sections is proposed, the section contains three resonant patches. We improve the beam scanning rate with the group delay theory, which are the key issues in the study of LWAs. Through theoretical analysis and simulation verification, the antenna parameters are optimized. The designed antenna has been fabricated and measured, and the simulated and measured results are in good agreement. A high scanning rate of 10.7 is achieved with a almost symmetry beam scanning range from −38° to 36°. Besides, the relative bandwidth of the fabricated antenna is reduced to only 6.9%.
