Abstract
Disclosed is a wideband antenna with a lowered standing wave ratio. The wideband antenna interposes a substance whose conductivity is about 0.1 through 10.0 as an interposition between a reference conductor and a radiation conductor; and thereby, the antenna reduces reflections of signals, and achieves a wider bandwidth as well as a sufficient gain with a lowered standing wave ratio. Also, the invention realizes a thin-type wideband antenna with a wider bandwidth and a sufficient gain, by interposing a magnetic substance whose relative permeability is more than 1 through about 8 as the interposition between the reference conductor and the radiation conductor.
Claims6
A wideband antenna, comprising:
- a reference conductor;
- a radiation conductor, at least parts of the reference conductor and the radiation conductor being disposed so as to face each other;
- a substance whose conductivity is about 0.1 [/Ωm] through 10 [/Ωm] in the operational radio frequency being interposed between the reference conductor and the radiation conductor of the wideband antenna;
- and
- a feed connected to at least the radiation conductor to transmit power thereto, wherein the feed has a tapered shape which widens as the feed approaches the connection to the radiation conductor.
