Abstract

Abstract : A novel meandered‐line‐loaded leaky‐wave antenna (LWA) is proposed. Two half‐mode substrate integrated waveguide‐based LWAs are placed face to face for obtaining high peak gains, and the meandered lines are introduced to acquire larger ratio of the beam scanning range to the operating frequency bandwidth. It is demonstrated that the operating frequency band can be narrowed by almost 1 GHz due to the meandered‐line structure under the condition that the scanning range keeps unchanged. The proposed LWA is fabricated and measured. Both simulated and measured results indicate that the designed antenna is a balanced LWA operating in frequency band 10.8–16 GHz (5.2 GHz centred at 13.4 GHz). Continuous beam scanning characteristic is observed from −60° to +34°, and comparisons are given out to validate the proposed design.
