METHOD AND DEVICE FOR GENERATING AND RECEIVING SUPER-SHORT CARRIER-FREE ELECTROMAGNETIC PULSED SIGNALS Russian patent published in 2007 - IPC H01Q21/06 

FIELD: short-range radio communication and radar systems.

SUBSTANCE: proposed method includes storage of electric field potential by means of storage capacitor, avalanche discharge of storage capacitor, reception and radiation of electromagnetic wave by means of receiving-radiating element, concurrent generation, transmission, and radiation of pulsed signals. Electric field potential is stored by storage capacitor simultaneously with its storage at receiver input from current waves formed by pulses of receiving electromagnetic wave across two separated conductors of transceiving element; avalanche discharge of storage capacitor is conducted simultaneously with generation of current waves in same conductors producing radiated electromagnetic wave pulse. Device implementing proposed method has sawtooth current pulse generator connected to storage capacitor, avalanche diode, receiving-radiating element, and receiver. Receiving-radiating element is made in the form of two separated conductors shorted out on one end; they are series-connected with avalanche diode and storage capacitor at input and parallel-connected with receiver input through controlled limiter.

EFFECT: enhanced antenna efficiency and gain, as well as noise immunity, reduced power loss.
