Abstract

An antenna arrangement for a wideband receiver having a transmit frequency band and a receive frequency band, the antenna arrangement comprising a first end-fed helical antenna (3) tuned to operate across only a first frequency band of the transceiver, and a second end-fed helical antenna (4) tuned to operate across only a second frequency band of the transceiver, wherein the first frequency band and the second frequency band are different.
