반사 제거 슬롯 쌍과 중앙 피드의 선형 배열이 있는 벽 후 도파관은 주파수에 따른 메인 빔의 기울기를 제거하고 안테나 조준 이득의 대역폭을 향상시키도록 설계되었습니다. 어레이는 뒷면에서 도파관 중앙에 공급됩니다. 방사 도파관의 길이는 절반으로 줄어들고 진행파 동작의 장선 효과가 억제됩니다. 저자는 Ansoft HFSS 시뮬레이터를 사용하여 반복 최적화에서 계산 부하를 줄이기 위해 별도의 단계로 어레이 설계 절차를 설정합니다. 균일한 여기를 갖는 중앙 피드 선형 어레이와 엔드 피드 등가물은 25.6GHz 작동용으로 설계되고 측정되었습니다. 측정된 성능은 중앙 피드의 설계와 장점을 확인합니다. 주파수 독립적 보어사이트 빔이 관찰되었으며 3dB 이득 감소를 위한 주파수 대역폭은 엔드피드 어레이에 비해 1.5배 향상되었습니다.

Abstract: Post-wall waveguide with a linear array of reflection-canceling slot pairs and center-feed is designed to cancel the frequency dependent tilting of the main beam and enhance the bandwidth of the antenna boresight gain. The array is fed at the center of the waveguide from the backside; the length of the radiating waveguide is halved and the long line effect in traveling wave operation is suppressed. Authors establish the array design procedure in separate steps to reduce the computational load in the iterative optimization by using Ansoft HFSS simulator. A center-feed linear array as well as an end-feed equivalent with uniform excitation is designed for 25.6 GHz operation and measured. The measured performances confirm the design and the advantage of the centre-feed; a frequency independent boresight beam is observed and the frequency bandwidth for 3 dB gain reduction is enhanced by 1.5 times compared to the end-feed array.
