Abstract

An antenna for a portable radio apparatus has a first antenna construction connected to the casing of the apparatus and a second antenna construction affixed to a base plate or earth plate which is incorporated in the casing. The first antenna construction has a movable joint which allows the first antenna construction to move between a first position where it is regarded as forming a part of the contour of the casing and a second position where it is protruded from the contour and regarded as being located in free space. The second antenna construction corrects the matching state of the first antenna construction such that adequate antenna radiation characteristics are set up in the first position. Optimal antenna characteristics are, therefore, achievable when the first antenna construction is in any one of the first and second positions.
