초록

본 논문에서는 슬리브 발룬을 활용하여 3-40GHz에서 향상된 방사 패턴을 나타내는 바이코니컬 안테나를 설계하였다. 안테나에서 상단 원뿔의 링 가장자리는 원통으로 구성되며, 특정 주파수에서 작동하는 슬리브 발룬은 안테나에 연결되어 급전 동축 케이블 표면의 누설 전류를 최소화한다. 본 제안한 슬리브 발룬으로 방사 패턴이 개선되었으며, 3dB 빔폭각도는 3-40GHz에서 67.1-101.1° 범위로 기존 안테나의 21-99° 범위보다 훨씬 넓은 특징을 갖는다.

We designed a biconical antenna with sleeve baluns that exhibited an improved radiation pattern from 3-40 GHz. In the antenna, the edges of the ring of the upper cone are blended to a cylinder. Sleeve baluns operating at specific frequencies are connected to the antenna to minimize leakage currents on the surface of the feeding coaxial cable. The radiation pattern was improved with the sleeve baluns, and the angular 3-dB beamwidth ranged from 67.1-101.1° over 3-40 GHz, which is much broader than the 21-99° of the conventional antenna.
