Technical Examples
  1. A digital receiving antenna device is connected to a digital television through a coaxial cable and has a casing, a flat antenna, a coaxial cable connector and a coaxial transmission line. The flat antenna is mounted in the casing and connected electronically to the coaxial cable through the coaxial transmission line. Since the coaxial transmission line has a fixed capacitance without regard to the distance between the feed point and the coaxial cable connector, a fixed capacitor is connected between the flat antenna and the coaxial cable connector. Therefore, the coaxial transmission line can be used as a transmission line for different size flat antennas, and each coaxial transmission line will have the same impedance. These different size digital receiving antenna devices can use the same antenna signal processing circuit and still have an impedance match between the flat antenna and the antenna signal processing circuit.
