Abstract

An antenna assembly comprises a panel (1) with suckers (3) for mounting it to a window or other vertical surface. A foil antenna (2) is formed on the panel (3). The antenna (2) may be coupled to a transceiver (8) by a feeder (6) so that in use it replaces the transceiver'"'"'s own antenna. In another arrangement, the antenna may simply re-radiate radio signals transmitted by the transceiver using its own antenna.

Claims

1. A transmitting system comprising:

a portable transceiver having output rf power amplifier and an integral antenna,

an antenna assembly, and

coupling means arranged to enable the transceiver to communicate via said assembly which thereby at least partially substitutes for said integral antenna,

wherein the antenna assembly comprises a panel, a metallic foil antenna on the panel and a sucker for harmlessly and releasably fixing the panel to a vertical surface.

2. A system according to claim 1, wherein the metallic foil antenna comprises an antenna producing circularly polarized radiation.

3. A system according to claim 2, wherein the metallic foil antenna comprises a crossed-dipole antenna.

4. A system according to claim 1, wherein the coupling means comprises a transmission line for coupling the output rf-power amplifier to the metallic foil antenna.

5. A system according to claim 1, wherein the coupling means comprises a first connector part on said assembly and a second connector part removably attached to the main part of transceiver and configured to co-operate with the first connector part, the second connector part including an output rf power amplifier of the transceiver.

6. A system according to claim 5, wherein communication signals are transmitted from the main part of the transceiver to the second connector part via a cable.

7. A system according to claim 5, wherein communication signals are transmitted from the main part of the transceiver to the second connector part by an infrared link.
