Kertas kerja ini membentangkan skim stereng pancaran terkawal frekuensi baru untuk sistem antena tatasusunan berperingkat (PAS). Skim yang dicadangkan menggunakan isyarat pembawa terkawal fasa untuk membentuk pancaran PAS. Dua pengayun tempatan (LO) dan talian tunda digunakan untuk menjana isyarat pembawa. Pembawa satu LO dibahagikan kepada cawangan, dan kemudian pembawa yang dibahagikan melalui garis kelewatan yang sepadan mempunyai hubungan fasa yang diingini, yang bergantung pada kekerapan ayunan LO. Untuk mengesahkan kebolehlaksanaan skim tersebut, pemancar PAS empat cawangan dikonfigurasikan dan diuji dalam jalur frekuensi 10-GHz. Keputusan mengesahkan bahawa rasuk yang terbentuk berjaya dikemudikan dalam julat yang luas, i.e., lebar pancaran 3-dB kira-kira 100 darjah, menggunakan kawalan frekuensi LO.

Abstract: This paper presents a novel frequency-controlled beam steering scheme for a phased-array antenna system (PAS). The proposed scheme employs phase-controlled carrier signals to form the PAS beam. Two local oscillators (LOs) and delay lines are used to generate the carrier signals. The carrier of one LO is divided into branches, and then the divided carriers passing through the corresponding delay lines have the desired phase relationship, which depends on the oscillation frequency of the LO. To confirm the feasibility of the scheme, four-branch PAS transmitters are configured and tested in a 10-GHz frequency band. The results verify that the formed beam is successfully steered in a wide range, i.e., the 3-dB beamwidth of approximately 100 degrees, using LO frequency control.
