  • Closely spaced antennas isolated through different modes
    Patent number: 9105986
    Abstract: Multi-antenna systems, including mobile devices having multiple antennas, are provided herein. A first antenna and a second antenna are operable at two or more of the same non-overlapping communication frequency bands. The first antenna and the second antenna are closely spaced and have different fundamental modes of operation such that the first antenna and second antenna are substantially isolated at the two or more non-overlapping communication frequency bands. The first antenna and second antenna having different fundamental modes can be a linear antenna, such as a monopole, dipole, PIFA, or PILA, and an aperture antenna, such as a slot or loop antenna.
