Kertas kerja ini membentangkan ciri-ciri sinaran antena susunan slot sfera rasuk kon terpolarisasi bulat untuk digunakan kepada pelanggan komunikasi satelit mudah alih. Struktur antena mudah dibuat iaitu, cincin pasangan slot berserenjang yang dipotong pada permukaan luar rongga sfera pengalir sepusat yang dikelilingi oleh permukaan kon pengalir dengan struktur suapan ringkas, dan probe elektrik linear yang teruja di tengah-tengah permukaan dalam rongga. Medan sinaran antena tatasusunan slot sfera dikira dengan menindih corak semua slot. Daripada keputusan berangka corak sinaran, dalam kedua-dua satah ketinggian dan azimut, adalah jelas bahawa rasuk kon direalisasikan. Arah rasuk ketinggian adalah rendah, yang sesuai untuk dipasang di unit pelanggan mudah alih darat yang terletak jauh dari khatulistiwa. Sistem penjejakan tidak diperlukan kerana corak azimut adalah omnidirectional. Directivity antena untuk pelbagai jejari sfera dan sudut kedudukan slot digambarkan sebagai garis panduan untuk reka bentuk. Keputusan eksperimen adalah dalam persetujuan yang baik dengan ramalan.

Abstract: This paper presents the radiation characteristics of a circularly polarized conical beam spherical slot array antenna for applying to the mobile satellite communication subscriber. The structure of the antenna is easy to fabricate i. e. , a ring of perpendicular slot pairs cut on an outer surface of a concentric conducting spherical cavity enclosed by the conducting conical surface with the simple feeding structure, and a linear electric probe excited at the center of the inner surface of the cavity. Radiation fields of a spherical slot array antenna are calculated by superposing the patterns of all the slots. From the numerical results of the radiation pattern, in both elevational and azimuthal planes, it is obvious that the conical beam is realized. The elevational beam direction is low, which is suitable for installing in the land mobile subscriber unit located far from the equator. The tracking system is not necessary because the azimuthal pattern is omnidirectional. Directivity of the antenna for various spherical radii and angles of slot positions are illustrated as the guidelines for the design. Experimental results are in good agreement with the predictions.
