Abstract:
1. An apparatus comprising: a first port configured to receive signals from a transceiver and to receive a first antenna, the first antenna being configured to operate in a first operational resonant frequency band; a second port configured to receive signals from a transceiver and to receive a second antenna, the second antenna being configured to operate in a second operational resonant frequency band; 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 the 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, to cause at least partial destructive interference between the first signal and the second signal at the first junction.
