Abstract:
This invention discloses a design and fabrication of a high performance HDTV Antenna to receive public airwave signals. The subject antenna consists of a high efficient broadband element and a pair of reflecting surfaces. The reflecting surfaces produce a focusing effect. The backside radiation of the antenna is redirected, making it more energized to receive signals from the front side. This is a very desirable feature in a weak signal environment. The reflecting surfaces provide additional benefits in reducing unwanted multiple reflecting signals which often cause unstable pictures. The broadband radiating element composed a pair of triangular shape radiators which is excited by a new art infinite balun. With this design, it is unnecessary to reposition the antenna in order to receive all available public channels. A fixed location is generally adequate to provide good reception to all stations.
