Multiband dual-antenna system

An antenna system comprising:

• a housing;
• a first wideband antenna integrated into a first metal portion of the housing, the first antenna configured to receive and transmit cellular radio frequency (RF) signals for a first set of frequency bands;
• a second wideband antenna integrated in a second metal portion of the housing different than the first metal portion of the housing, the second antenna configured to receive and transmit RF signals for a second set of frequency bands, the second wideband antenna further comprising two segments, the two segments configured to operate as a multiple input multiple output (MIMO) antenna independent of the first wideband antenna;
• electrically non-conductive splits disposed in the housing between the first and second portions for electrically isolating the first and second antennas from one another;
• a first antenna feed structure configured to feed RF signals in the first set of frequency bands into the first antenna;
• a second antenna feed structure configured to feed RF signals in the second set of frequency bands into the second antenna;
• and
• a ground plane disposed in the housing and coupled to the first antenna and the second antenna.
