1. An apparatus comprising:
- a first antenna configured to operate more efficiently in a first frequency band than in a second frequency band, the first antenna being configured to receive primary signals within the first frequency band and diversity signals within the second frequency band;
a second antenna configured to operate more efficiently in the second frequency band than in the first frequency band, the second antenna being configured to receive primary signals within the second frequency band and diversity signals within the first frequency band;
a transceiver comprising;
a first group of ports configured to receive the primary signals within the first frequency band;
a second group of ports configured to receive the diversity signals within the second frequency band;
a third group of ports configured to forward transmission signals within the first frequency band;
a fourth group of ports configured to forward transmission signals within the second frequency band;
a fifth group of ports configured to receive primary signals within the second frequency band; and
a sixth group of ports configured to receive diversity signals within the first frequency band; and
a plurality of radio-frequency (RF) front-end modules including a first RF front-end module and a second RF front-end module, the first RF front-end module configured to direct the primary signals within the first frequency band from the first antenna to the first group of ports, to direct the diversity signals within the second frequency band from the first antenna to the second group of ports, and to direct the transmission signals within the first frequency band from the third group of ports to the first antenna, and the second RF front-end module configured to direct the transmission signals within the second frequency band from the fourth group of ports to the second antenna, to direct the primary signals within the second frequency band from the second antenna to the fifth group of ports, and to direct the diversity signals within the first frequency band from the second antenna to the sixth group of ports.

Abstract
An antenna system is disclosed. A wireless device includes two antennas. The first antenna is optimized at a first frequency band. The second antenna is optimized at a second frequency band. The signals received from respective optimized frequency bands are used as primary received signals. The signals having frequencies beyond respective optimized frequency bands are used as diversity signals. Likewise, the signals transmitted from a transceiver to base stations are sent to respective antennas based upon their frequency bands. By employing this optimized antenna configuration, the wireless device can provide high quality wireless signals for both frequency bands.
