Abstract : Using unmatched elements in a series-fed, periodic array produces high input VSWR at frequencies where a structural stopband occurs. The monopole-slot antenna is a two-port element which can be designed to provide broadband match to a stripline feeder. Then no additional matching is required to eliminate a structural stopband. A frequency scanning array was designed and tested to illustrate that monopole-slot elements can be used in a series-fed array without causing an impedance anomaly at broad-side scan. (Author)
