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 lambda(0)) improves the back lobes by 9 dB at 4.7 GHz compared with the original half-width MLWA. (C) 2009 Wiley Periodicals, Inc.
