<p>A transmission signal and receiver signal antenna arrangement comprises an electromagnetic lens 302 having a variation in permittivity along a predetermined plane for guiding signals along the said plane. A plurality of radiating elements and a plurality of detecting elements are arranged along a line that lies within the said plane. The said elements may be narrow beam, closely packed waveguides or striplines, with no gap between them. The lens 302 may be a Luneburg lens. Also disclosed is a method of operating a communication signal transceiver which comprises determining a first element of the transceiver that radiates or detects electromagnetic signals when the transceiver is in communication, in a first direction, with a remote device. Then selecting a second element of the transceiver, that is adjacent to the determined first element, and activating the second element for communication with the device in the reverse communication direction to that of the first element. The antenna arrangement may be compact, easy to use and capable of operating in full or half duplex communications.</p> |
