Abstract
A cable to waveguide transition apparatus having a signal accumulation form of a backshort is disclosed. The cable to waveguide transition apparatus having a signal accumulation form of a backshort, includes: a waveguide; a RF probe for transferring a radio frequency (RF) signal to the waveguide; and a backshort having the signal accumulation form for reflecting the RF signal excited from the RF probe, wherein the backshort reflects a first fundamental frequency signal excited from the RF probe to have a phase identical to a phase of a second fundamental frequency signal excited from the RF probe to an aperture of the waveguide, and reflects a first 2-order harmonic frequency signal excited from the RF probe to have a phase reverse to a phase of a second 2-order harmonic frequency signal excited to an aperture of the waveguide in order to eliminate the 2-order harmonic frequency signal.
