Abstract
The design and experimental verification of a novel dualband symmetric comb-slot loaded patch antenna for phased array applications is presented. The proposed antenna supports two well-defined sub-bands, with good bandwidths, and a frequency ratio of nearly 1.4:1. The antenna also exhibits consistent radiation patterns with low crosspolarization levels at both sub-bands. The single-layer architecture and compact electrical dimensions make it suitable for application in wide scanning phased arrays.
