본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음Since this is an open matter, no full text was included.

제2도(가)(나)는 본 발명에 따른 편파 변환 방법을 나타내기 위한 장치의 사시도 및 측면도.2 (a) (b) is a perspective view and a side view of a device for illustrating a polarization conversion method according to the present invention.

제3도는 1/4파장판에 의한 편파 변환시의 전체모양도.3 is an overall view of polarization conversion by a quarter wave plate.

Claims (1)

원형도파관내에 1/4파장을 삽입설치하여 편파를 변환시키는 통상의 것에 있어서, 상기 원형 도파관(1)내에 2개의 1/4파장판(2)(3)을 차례로 삽입 배열 설치한뒤, 상기 2개 파장판의 설치각도(θ1)(θ2)을 0°또는 45°로 선택 가변시켜 수평 및 수직 그리고 원편파가 발생되도록 함을 특징으로 하는 초고주파대 안테나의 편파 변환 방법.In the conventional method of inserting 1/4 wavelength into the circular waveguide and converting polarization, the two quarter wave plates 2 and 3 are sequentially inserted into the circular waveguide 1, and then 2 A polarization conversion method for an ultra-high frequency antenna, characterized in that horizontal, vertical and circular polarizations are generated by selectively varying the installation angles (θ 1 ) (θ 2 ) of the open wave plates to 0 ° or 45 °. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
