Abstract
An antenna for radio apparatus comprises a first conductor taking a helical form, a second conductor which extends to and fro in sequence substantially in a direction of the center axis of the helical form of the first conductor to take, as a whole, a meandering form which is spaced apart from the first conductor and surrounds the center axis, and a dielectric member which lies at least between the first and second conductors. A portion of the first conductor is electrically connected to a portion of the second conductor, and either a portion of the first conductor or a portion of the second conductor acts as a feeding point.
