Abstract
A novel short half‐width microstrip leaky wave antenna (MLWA) with suppressed back lobes is introduced. The design contains an oblique shape termination and a linked square metal with a grounded via hole. The oblique shape termination changes the direction of the reflected wave, and a linked square metal with a grounded via hole guides the remainder power of the reflected wave to the ground plane. As a result, the large back lobe of the short half‐width MLWA could be suppressed. The measured results show that the proposed design (length of only 1 λ~0~) improves the back lobes by 9 dB at 4.7 GHz compared with the original half‐width MLWA. © 2009 Wiley Periodicals, Inc.
