Abstract
A broadband microwave coplanar antenna suitable for use in singular antenna or antenna array dispositions in a plurality of military and other present day uses. The disclosed antenna combines desirable characteristic of the patch and slot antenna forms into an arrangement having both patch resonances and slot resonances. These resonances may be individually accessed and either combined in frequency location or dispersed in frequency to accomplish a broadband combination antenna characteristic. Broadband electrical impedance characteristics are also provided in the dispersed resonance arrangement. The antenna includes a coplanar ground plane member disposed surrounding the active patch/slot element with both physical dimensions of the active patch/slot element and spacings from the ground plane element determining the resonances.
