摘要： A wireless device that covers the wireless communication frequency bands incorporates a frequency domain monitor to adaptively modify the time domain waveform of a clock signal to suppress even order harmonics caused by asymmetry in the driver or load. Even order harmonics may be avoided where clock shifting is not possible and when combined with clock shifting the wireless device allows avoidance of both harmonics when two harmonics fall in-band of the receiver.

摘要： An impedance plane has an elongated strip ship. The impedance plane approximates a magnetic conductor within a particular frequency band. A sector antenna is coupled to one side of the impedance plane. The sector antenna has a planar form factor with dimensions contained within the elongated strip. The sector antenna has a radiation pattern in the particular frequency band that is flared out from the impedance plane at a particular angle.

摘要： An impedance plane has an elongated strip ship. The impedance plane comprises an Artificial Magnetic Conductor (AMC) within a particular frequency band. A sector antenna is coupled to one side of the impedance plane. The sector antenna has a planar form factor with dimensions contained within the elongated strip. The sector antenna has a radiation pattern in the particular frequency band that is flared out from the impedance plane at a particular angle.

摘要： A method and an apparatus for passive interference cancellation are provided. The Apparatus includes a first and second radio operating on a same frequency band, a first and second coupler and a first phase shifter. The first radio includes a first radio transceiver and a first radio antennae. The second radio includes a second radio antennae located a predetermined distance from the first radio antennae. A first coupler and second coupler are adjusted according to a coupling loss between the antennas. The first radio transceiver transmits a first signal. The first signal is divided by the first coupler to a first portion and a second portion. The first portion moves through the first radio antennae and is received by the second radio antennae. The second portion moves through the first phase shifter. Both portions of the first signal meet and cancel to achieve a specified isolation between the radios.
