Abstract

Provided a self-biased receiver system using a multi-fed antenna, including: at least one first port connected to an electronic circuit; and a second port connected to a feeder forming a DC (direct current) voltage using an input electromagnetic wave and feeding the DC voltage to the electronic circuit.

Claims

1. A receiver system comprising:

an antenna, comprising at least one of;

a first port connected to an electronic circuit;

a second port connected to a feeder forming a DC (direct current) voltage using an input electromagnetic wave received by the antenna and feeding the DC voltage to the electronic circuit; and

a radiator sheet radiating the electromagnetic wave,

wherein the first port is disposed on an identical plane to the radiator sheet.

2. The receiver system of claim 1, wherein the electronic circuit is at least one of a transmitter circuit, a receiver circuit, an active circuit, and a passive circuit.

3. The receiver system of claim 1, wherein the feeder is a rectenna.

4. The receiver system of claim 3, wherein the rectenna comprises:

a diode generating harmonic frequency components of the electromagnetic wave; and

a filter filtering a signal generated by the diode to output a DC voltage.

5. The receiver system of claim 3, wherein a charging element charging a DC power output from the rectenna is installed at an output node of the rectenna.

6. The receiver system of claim 1, wherein the second port is disposed perpendicular to the radiator sheet.

7. The receiver system of claim 6, wherein the radiator sheet is formed in a disc shape and comprise a side cut in a fan shape at a predetermined angle.

8. The receiver system of claim 7, wherein outputs of the harmonic frequencies generated by the diode are intercepted.

9. The receiver of claim 1, wherein the first port is disposed at a distance of an angle of 30°

from a cut part of the antenna.
