Antenna system with multiple transmit paths

An antenna system comprising:

• a set of antennas;
• and
• a set of signal paths to support wireless communication for a wireless device, the signal paths including:
• a first signal path including a first duplexer, the first signal path being operably connected to a first antenna of the set of antennas and configured to support transmission to and primary receive from a first cell group of a wireless network;
• a second signal path including a second duplexer, the second signal path operably connected to a second antenna of the set of antennas and configured to support transmission to and primary receive from a second cell group of the wireless network;
• a third signal path including a first filter, the third signal path connected to a third antenna of the set of antennas and configured to support antenna diversity receive from the first cell group of the wireless network;
• a fourth signal path including a second filter, the fourth signal path connected to a fourth antenna of the set of antennas and configured to support antenna diversity receive from the second cell group of the wireless network;
• a first switch operatively connected to the set of antennas, the second signal path, and the fourth signal path;
• a second switch operatively connected to the first switch and the first signal path, the first signal path being configured for a first signal band;
• a third switch operatively connected to the first switch and the third signal path, the third signal path being configured for the first signal band;
• a fifth signal path operatively connected to the second switch and configured for a second signal band;
• and
• a sixth signal path operatively connected to the third switch and configured for the second signal band,
• wherein the second switch is operable to switch between the first signal path and the fifth signal path to enable wireless communication via the first signal band, and the third switch is operable to switch between the third signal path and the sixth signal path to enable wireless communication via the second signal band.
