Abstract
An improved continuous transverse stub (CTS) antenna has coplanar waveguide (CPW) feed elements spaced apart aligned in parallel and mounted perpendicular to a planar substrate base made of a low dielectric material. A continuous transverse stub extends perpendicularly through a clearance gap in the CPW feed elements on the ground plane of the substrate base. The antenna is fed with a simple coplanar waveguide transmission line formed by the parallel CPW elements. The antenna employs the coplanar waveguide with CTS technology, preferably in a planar microstrip configuration, to produce a broadside radiation pattern with a maximum in the +z direction, perpendicular to the plane of the antenna. The CPW-CTS antenna offers the advantages of a broadside radiation pattern, low input impedance, high radiation efficiency, low fabrication cost, use of simple coaxial or microstrip transmission line feed, and simple integration with microstrip circuitry in a transceiver front-end. The CPW-CTS antenna may be integrated in a single frequency band or in multiband arrays and could provide radiation beam steering capability when integrated with a substrate of tunable dielectric material such as BSTO.
