HDTV: Wideband Planar Antenna

University of Kansas
posted on 10/25/2005

This technology provides for improvement of existing antennas. It improves the reception of digital TV broadcasts, especially in distant fringe areas or locations without a clear path to a transmitting tower. The planar antenna provides a high degree of multipath interference rejection and extremely wide antenna bandwidth characteristics, allowing an unusually wide range of frequencies to be received with a single antenna.

Suggested Uses

TV reception in rural areas. Could be adapted for use in a variety of communication and radar system applications

Detailed Description

This technology provides for improvement of existing antennas. It improves the reception of digital TV broadcasts, especially in distant fringe areas or locations without a clear path to a transmitting tower. Television reception often suffers from "multipath" problems, such as ghosting in the case of analog television receivers or excessive digital data errors in the case of digital television receivers. Audio dropouts, display pixilation, or abrupt loss of all audio and video output may result from digital data errors. The planar antenna provides a high degree of multipath interference rejection and extremely wide antenna bandwidth characteristics, allowing an unusually wide range of frequencies to be received with a single antenna.
