Summary:
We have proposed a multi-band antenna which is composed of several conductive wires with a coupling effect. It is fed with a semi-rigid coaxial cable. In order to suppress the leak current, a bazooka type balun was introduced at the feed point. However the bazooka type balun works at only one resonant frequency. Therefore, a novel method has been investigated to set multiple feed points on the antenna for multiple frequencies. This paper explains the feeding method for multiple frequencies. It was confirmed that the antenna is able to work at three frequencies simultaneously from analytical results.
