Abstract
An antenna device for a hand-portable radio communication unit including a casing with a ground plane means cooperating with the antenna device. The antenna device comprises first and second radiating elements (1a, 1b) being tuned to different resonant frequencies and having a common feed point (1c). The radiating elements (1a, 1b) are disposed in a compact arrangement on a support means (3) so as to be confined entirely in the casing (2).
Claims35
An antenna device for a hand-portable radio communication unit including a casing, in which a ground plane means having at least one edge is disposed, said antenna device comprising:
- first and second radiating elements carried by a support means,
- said first and second radiating elements being tuned for different resonant frequencies,
- said first and second radiating elements being disposed in a compact arrangement on said support means and extending from at least one feed point along a longitudinal axis to a first and a second free end, respectively, and
- said support means for mounting with said first and second radiating elements located adjacent to said at least one edge of said ground plane means so as to be confined entirely in said casing.
An antenna device for a hand-portable radio communication unit including a casing, in which a ground plane means having at least one edge is disposed, said antenna device comprising at least one radiating element carried by a support means and extending along a longitudinal axis from a feed point to a free end, and a radiating rod element, which is connectable to said feed point so as to be coupled electrically in parallel to said at least one radiating element, said at least one radiating element carried by said support means is an internal element located entirely in said casing with its longitudinal axis oriented substantially in parallel to said one edge of said ground plane means, said longitudinal axis being perpendicular to said rod element.
A radio communication unit comprising:
- an antenna device;
- a hand-portable radio communication unit including a casing, in which a ground plane means having at least one edge is disposed;
- first and second radiating elements carried by a support means;
- said first and second radiating elements being tuned for different resonant frequencies;
- said first and second radiating elements being disposed in a compact arrangement on said support means and extending from at least one feed point along a longitudinal axis to a first and a second free end, respectively, and
- said support means for mounting with said first and second radiating elements located adjacent to said at least one edge of said ground plane means so as to be confined entirely in said casing.
