  • Apparatus, methods, computer programs and computer readable storage mediums for wireless communications
    Patent number: 8886135
    Abstract: An apparatus including a first port configured to receive signals from a transceiver and to receive a first antenna; a second port configured to receive signals from a transceiver and to receive a second antenna; a first reactive component coupled to the first port; a second reactive component coupled to the first reactive component at a first junction and to the second port, wherein at least the first reactive component is configured to have an impedance that shifts the phase of a first signal, in a second operational resonant frequency band, received from the first antenna, and the second reactive component is configured to have an impedance that shifts the phase of a second signal, in the second operational resonant frequency band, received from the transceiver, so that the first signal and the second signal at least partially destructively interfere with one another at the first junction.
