Radio repeater using the non-radiative dielectric waveguide

Abstract

A radio repeater wherein a reflective negative resistance amplifier, using the negative resistance of a Gunn diode, is applied at one side of a dielectric waveguide, enabling signals to be inputted through the input terminal dielectric waveguide, circulated in the circulator and enter the Gunn diode. Reflected waves amplified in the Gu diode exit the output terminal dielectric waveguide. A radio repeater is provided on the non-radiative dielectric waveguides using the multi-space non-radiative dielectric waveguides, which receives a frequency, amplifies it, and retransmits the amplified signals to any direction. With a dielectric band inserted in the radio repeater, directions for reception and transmission can be freely changed. Using the radio repeater, a small size radio repeater of low power consumption may be made.
