  • Patent number: 11563279
    Abstract: A switchable dual polarization patch antenna with improved cross polarization isolation to concurrently radiate horizontally polarized signals and vertically polarized signals. A planar conductor is arranged with a first terminal and a second terminal that are vertically spaced on a portion of the planar conductor to radiate a component of a vertically polarized signal with zero degrees of phase shift from one of the two terminals and radiate another component of the vertically polarized signal having a 180 degrees of phase shift from the other of the two terminals. A hybrid coupler can provide the 180 degrees of phase shift. A horizontally polarized signal is radiated from a third terminal that is horizontally spaced on another portion of the planar conductor and coupled to a horizontally polarized signal source. The direction of the 180 phase shift for the first and second components of the vertically polarized signal may be selected.

  • Patent number: 9401738
    Abstract: A method of closed-loop antenna tuning (CLAT) search strategy based on maximum Relative Transducer Gain (RTG) is proposed. A search region that account for TX input mismatch and forward voltage gain is pre-computed. The search region that is independent of antenna load can be pre-computed to reduce the computation complexity. The Maximum RTG is searched by estimating antenna S-parameters corresponding to a good load match. The search is conducted between the peak forward voltage gain and the best load match. Global optimal with reasonable RTG can be found with limited number of iterations. The transmitter search region can further be constrained by the receiver path mismatching.
