Abstract: This paper presents two miniaturized slow wave structures in microstrip leaky-wave antennas (MLWAs) which operate about 8 GHz. The effects of these structures on the scan angles have been compared in the paper. The designed interdigital capacitors and folded-back line have been investigated with ADS Momentum software. It has been shown that the interdigital capacitors (IDCs) yield to a broad scan angles from +53 to -74 degree, while the foldedback line inductor scans only the positive angles.
Index Terms: leaky-wave antenna (LWA), scan angle, slow wave structure, periodic structure.
