摘要： An antenna system and method utilize a splitter electrically connectable to a single antenna for splitting an RF signal into two signals. A variable phase shifter shifts the phase of one of the signals. A combiner combines the phase shifted and non-phase shifted signals to produce a conditioned signal. A quality examiner circuit changes the amount of phase shift provided by the variable phase shifter to produce a plurality of different conditioned signals. The quality examiner circuit then determines a quality of each conditioned signal and changes the phase shift again to provide the highest quality conditioned signal to a receiver.

摘要： An antenna system for receiving an RF signal from a first antenna and a second antenna includes a phase shift circuit. The phase shift circuit shifts a phase of the RF signal from the second antenna by one of a plurality of possible phase shifts to produce a phase shifted signal. A combiner combines the RF signal from the first antenna and the phase shifted signal to produce a combined signal. A comparator circuit compares a signal quality of the combined signal with a minimum threshold value to determine if the signal quality of the combined signal is equal to or greater than the threshold value. The comparator circuit is in communicative control of the phase shift circuit and maintains the phase shift of the RF signal received by the second antenna in response to the signal quality of the combined signal being equal to or greater than the threshold value.

摘要： An antenna includes a ground plane, a dielectric, and an active radiating element. The dielectric is disposed on the ground plane, and the active radiating element is embedded in the dielectric for transmitting and/or receiving an RF signal. The antenna also includes a feeding element and a passive radiating element. The feeding element extends into the dielectric and is electrically coupled to the active radiating element. The passive radiating element is disposed on the ground plane and surrounds a periphery of the dielectric for perturbating the RF signal. The ground plane has a plurality of edges. At least one of the edges extends as a curvilinear lip. The curvilinear lip extends in a direction opposite the passive radiating element for directing the RF signal and for preventing abrupt discontinuity of the RF signal.
