Dual-band antenna element for L-band and S-band phased array

Two-port, dual band antenna element for wide-angle scanning planar phased array is designed. The antenna element consists of two parts: the annular slot fed by a microstrip line and a circular patch fed by an H shaped slot. The annular slot is used to operate over the L-band and the circular patch over the S radar band. The antenna element demonstrates dual-band performance with sufficient bandwidth in both bands and consistent radiation patterns. Due to its small dimensions, the element is well-suited for application to wide-scan phased arrays in multiscale configuration.
