Kertas kerja ini membentangkan antena tatasusunan terkutub bulat berstruktur meta dengan sudut imbasan lebar. Untuk meluaskan sudut imbasan antena tatasusunan, kertas kerja ini menyiasat lebar pancaran antena unit dan kesan gandingan antara elemen tatasusunan, yang kedua-duanya memberi kesan secara langsung kepada prestasi stereng. Hasilnya, jarak tatasusunan optimum, konfigurasi mod dan struktur antena dijelaskan. Dengan menggunakan ciri-ciri antena resonans mu-sifar kecil (MZR), adalah mungkin untuk mereka bentuk antena pada jarak tatasusunan optimum untuk lebar pancaran lebar. Di samping itu, dengan mengubah suai melalui konfigurasi kedudukan dan jurang antena, adalah mungkin untuk mengoptimumkan konfigurasi mod untuk pengasingan optimum. Akhirnya, sudut kemudi 3dB 66° berjaya ditunjukkan menggunakan tatasusunan antena 1x8 MZR CP tanpa sebarang struktur penyahgandingan tambahan. Corak rasuk yang diukur pada sudut imbasan 0°, 22°, 44°, dan 66°setuju baik dengan corak rasuk simulasi.

Abstract: This paper presents a meta-structured circular polarized array antenna with wide scan angle. In order to widen the scanning angle of array antennas, this paper investigates unit antenna beamwidth and the coupling effects between array elements, both of which directly affect the steering performance. As a result, the optimal array distance, the mode configuration, and the antenna structure are elucidated. By using the features of the miniaturized mu-zero resonance (MZR) antenna, it is possible to design the antenna at optimum array distance for wide beamwidth. In addition, by modifying via position and gap configuration of the antenna, it is possible to optimize the mode configuration for optimal isolation. Finally, the 3dB steerable angle of 66° is successfully demonstrated using a 1x8 MZR CP antenna array without any additional decoupling structure. The measured beam patterns at a scan angle of 0°, 22°, 44°, and 66°agree well with the simulated beam patterns.
