導波管・伝送線路変換器、およびアンテナ装置
Document Type and Number:
Japanese Patent JP5044536
Kind Code:
B2
Abstract:
A transformer between waveguide and transmission-line includes a high-frequency circuit module, transmission-lines, a waveguide, and feed pins. The high-frequency circuit module has differential-pair terminals to input and output a differential signal. The transmission-lines are connected to the differential-pair terminals. The waveguide includes a first to third metal walls. The feed pins are connected to the transmission-lines inside of the waveguide. The feed pins have a first distance of approximately (λg/2) from each other. One of the feed pins has a second distance of approximately (λg*(1+2α)/4) from the third metal plane. “λg” is a wavelength in the waveguide and “α” is an integer which is equal or larger than “0”. Each of the feed pins has a third distance of approximately (a/2) from the first or second wall. “a” is length of the waveguide along the third metal wall.
