Abstract :
In this paper, a printed leaky-wave antenna with a sinusoidally modulated surface reactance (SMRS) is reported. The TM polarized antenna consists of metallic strips with periodically varying gaps printed on a grounded dielectric substrate. The designed antenna radiates at thirty degrees from broadside at 10 GHz, and exhibits a gain of 14.7 dB. Theoretical, simulation, and experimental results are shown. A design procedure allowing for an arbitrary radiation angle is outlined.
