  • Antenna and RF front-end arrangement
    Patent number: 9503150
    Abstract: An antenna and RF front-end arrangement include at least one LTE or WCDMA Tx&Rx antenna, one MIMO Rx or diversity antenna adapted for low band LTE or WCDMA and one MIMO Rx or diversity antenna adapted for high band LTE or WCDMA. At least one of the MIMO Rx or diversity antennas is adapted for transmitting and receiving WLAN and/or BlueTooth signals. Therefore, a dedicated WLAN antenna is not required and the number of antennas can be reduced.
