Abstract
A microstrip antenna suitable for omnidirectional S-band operation is formed by the application of a plurality of microstrip radiating elements to the exterior surface of a dielectric tube. The microstrip radiating elements are fed by a branched microstrip input feed line connected to the elements. In the illustrated embodiment, the microstrip radiating elements are fed in-phase by feed line. A substantially cylindrical reflector tube is disposed within the dielectric tube.
