Abstract
A microstrip antenna array takes the form of a feeder strip and a plurality of elements, each in the form of a strip attached to the feeder strip at one end and having an open-circuit termination at the other. Arrays are disclosed which use standing waves in the feeder strip and which use travelling waves. The elements can be of various widths to provide a modulated array and, in the case of a travelling wave array, to compensate for attenuation in the wave in the feeder strip. A frequency-swept array and a circularly polarized array are described.
