High Performance (mini-cube) Indoor HDTV Antenna |
摘要 |
This invention discloses a design and fabrication of a high performance compact antenna to receive public airwaves HDTV signals. The subject antenna consists of a high efficient cone shape broadband element excited over a small metal ground plane. A reflecting surface is implemented to help rejecting any unwanted multiple reflecting signals from the surrounding objects. Outstanding impedance characteristics and broad pattern coverage have been obtained. The pattern coverage is omnidirectional. The polarization is linear along the cone axis. This antenna design operates well in a weak signal environment and as a result the antenna can receive a large number of public channels. Although the antenna measures only 5¾×5¾×3¼ inches in a cubical enclosure or in a 6⅜ inches diameter by 3½ inches depth cylindrical body, the antenna packaged in either enclosure can receive more public channels than a much larger antenna twice of its size. Two invention antennas have been fabricated and tested and the test results confirmed that all antennas of either enclosure were performing well as expected. The invention antennas receive more than 130 public channels.
