摘要 |
There is provided an antenna comprising: a ground conductor; and an antenna element portion for sending and receiving electromagnetic wave signals, the antenna element portion comprising: a coaxial cable including a center conductor and an outer conductor; a feeding point connected to a feeding system and disposed between the ground conductor and a first end of one of the center and outer conductors; a short-circuit portion electrically connecting the ground conductor and a first end of the other one of the center and outer conductors; and a conductor connection portion electrically connecting second ends of the center and outer conductors each other. In addition, an overall length of the coaxial cable is not more than ½ of a wavelength corresponding to the minimum series resonance frequency; and a distance between the center and outer conductors is not more than 1/100 of a wavelength corresponding to the minimum operation frequency. |
