Abstract
A handset includes two antennae, wherein one antenna is solely dedicated to multi-band frequency division multiplexed signals. The first antenna connects to an antenna switch. The antenna switch further connects to receivers and transmitters of time division band standards. The second antenna transceives a multi-band frequency division multiplexed signal. A modular filter receives the multi-band frequency division multiplexed signal and separates the frequency bands. To provide diversity, the antenna switch connects to a receiver for each frequency division band standard.
