Antena sektor memberikan banyak kelebihan seperti apabila digabungkan dengan antena rasuk sempit, ia menjadi amat berkesan dalam mencapai sistem komunikasi tanpa wayar berkelajuan tinggi dan ia membantu dalam memudahkan struktur. Antena ini mempunyai kelemahan kerana apabila bilangan sektor meningkat, saiz antena meningkat dengan cepat. Oleh itu, pengecilan antena sektor telah menjadi topik penyelidikan utama. Calon yang menjanjikan sedang menggunakan antena jenis tatasusunan berperingkat; namun, antena ini memerlukan litar penukar fasa untuk pengimbasan rasuk dan secara amnya litar suapan untuk antena jenis ini adalah sangat rumit. Untuk menangani isu ini, kami mencadangkan litar suapan memilih sendiri yang dikawal oleh litar kawalan yang sama dan dikendalikan sama dengan port tunggal konvensional nsuis lontaran ke-ke (SPNT). Kami membuat antena 12-sektor silinder kecil pada 19 GHz menggunakan litar suapan yang dicadangkan untuk tujuan pengesahan. Tambahan pula, kertas kerja ini menjelaskan kaedah reka bentuk litar suapan ini di mana diameter antena ialah 71 mm, dan keputusan jelas menunjukkan bahawa keuntungan adalah lebih daripada 12 dBi.

Abstract: Sector antennas provide many advantages such as when combined with a narrow beam antenna, they become particularly effective in achieving high-speed wireless communication systems and they aid in simplifying the structure. These antennas have a drawback in that as the number of sectors increases, the antenna size rapidly increases. Therefore, downsizing the sector antenna has become a major research topic. A promising candidate is utilizing a phased-array type antenna; however, this antenna requires a phase-shifter circuit for beam scanning and generally the feeding circuit for this type of antenna is very complicated. To address these issues, we propose a self-selecting feeding circuit that is controlled by the same control circuit and is operated similarly to the conventional single port n-th throw (SPNT) switch. We fabricated a small cylindrical 12-sector antenna at 19 GHz employing the proposed feeding circuit for verification purposes. Furthermore, this paper clarifies the design method of this feeding circuit where the antenna diameter is 71 mm, and the results clearly show that the gain is more than 12 dBi.
