The design and experimental verification of a novel dual‐band 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 cross‐polarization levels at both sub‐bands. The single‐layer architecture and compact electrical dimensions make it suitable for application in wide scanning phased arrays. © 2015 Wiley Periodicals, Inc.
