ANTENNA SYSTEM

摘要

The invention relates to antenna systems for wireless communications networks, and in particular concerns antenna systems for low power licence exempt broadband wireless local area networks (WLANs). In one embodiment the antenna system comprises: a first antenna configured for receiving radio signals for a receiver element of a radio transceiver, and a second antenna for transmitting radio signals generated by a transmitter of the transceiver. The gain of the first antenna is greater than the gain of the second antenna. The lower gain of the dedicated transmit antenna enables the radiated power to be minimised without adversely affecting range. Switching means are provided for connecting either the first antenna to the receiver or connecting the second antenna to the transmitter.
