Abstract: An antenna is described including a slot formed in a cavity, a substrate configured to cover a portion of the cavity and the slot, and a first port and a second port configured to supply power to the antenna using a first feeding line and a second feeding line. Each of the feeding line and the second feeding line is connected to the slot in a vertical direction and disposed to be separate from one another. A first input impedance of the antenna from the first port differs from a second input impedance of the antenna from the second port.

Abstract: A receiver and a transmitter that copes with interference in a super-regenerative communication system, and a method of using the receiver and the transmitter, are provided. A super-regenerative receiver includes a resonance frequency adjusting unit configured to adjust a resonance frequency associated with a filtering band of a transmission signal that is received from a transmitter. The super-regenerative receiver further includes an oscillation signal generating unit configured to generate an oscillation signal, using a positive feedback amplification, based on the resonance frequency and the transmission signal. The super-regenerative receiver further includes an oscillation characteristic detecting unit configured to detect a characteristic of the oscillation signal. The super-regenerative receiver further includes a determining unit configured to determine whether interference is included in the transmission signal based on the characteristic of the oscillation signal and the resonance frequency.

Abstract: Provided is a method and an apparatus to calibrate an output of an oscillator. The method includes calibrating the output frequency of the oscillator to be a predetermined frequency. The method also generates a differential signal corresponding to the calibrated frequency, and operates the oscillator in response to the differential signal. The oscillator is controlled by the differential signal to remove common mode noise.
