Kertas kerja ini membentangkan penambahbaikan ciri-ciri pengasingan port-to-port bagi dwijalur dwi-kutub linear dan antena jalur lebar berbilang cincin (MR-MSA) yang disuap oleh dua kuar L. MR-MSA jalur dwi-kutub linear dan jalur lebar terdiri daripada dua tompok gelang bulat dan dua kuar L yang disusun dalam substrat dielektrik berbilang lapisan. Dengan menggunakan substrat tebal untuk kuar-L dan menyusun dua tompok gelang sebagai elemen sinaran, antena yang dicadangkan mengendalikan ciri jalur lebar dan dwijalur. Tambahan pula, dengan menyusun dua L-probe pada kedudukan ortogon, antena yang dicadangkan boleh memancarkan polarisasi linear dwi. Dalam kertas ini, untuk menambah baik ciri pengasingan port-ke-port bagi dwi-jalur dwi-kutub linear dan jalur lebar MR-MSA yang disuap oleh dua kuar L, melalui yang disambungkan ke satah tanah di tengah-tengah unsur sinaran disusun. . Lebar lebar pecahan di bawah pantulan -10dB yang diperolehi oleh simulasi MR-MSA dengan melalui adalah 17.0% dan 14.4%. Tambahan pula, ciri pengasingan simulasi adalah lebih daripada 21.0dB dan 17.0dB dalam kedua-dua jalur. Penambahbaikan ciri pengasingan antara dua port serta prestasi dwi-jalur dan jalur lebar MR-MSA yang dicadangkan dengan melalui telah disahkan oleh simulasi dan pengukuran.

Abstract: This paper presents improvement of port-to-port isolation characteristics of a linearly dual-polarized dual-band and wideband multi-ring microstrip antenna (MR-MSA) fed by two L-probes. The linearly dual-polarized dual-band and wideband MR-MSA consists of two circular ring patches and two L-probes arranged in a multi-layered dielectric substrate. By using a thick substrate for the L-probe and arranging two ring patches as radiation elements, the proposed antenna operates wideband and dual-band characteristics. Furthermore, by arranging two L-probes at the orthogonal positions, the proposed antenna can radiate dual linear polarizations. In this paper, for improving port-to-port isolation characteristics of the linearly dual-polarized dual-band and wideband MR-MSA fed by two L-probes, a via connected to the ground plane at the center of the radiation elements is arranged. The fractional bandwidths below -10dB reflection obtained by the simulation of the MR-MSA with the via were 17.0% and 14.4%. Furthermore, the simulated isolation characteristics were more than 21.0dB and 17.0dB in the two bands. Improvement of the isolation characteristics between two ports as well as the dual-band and wideband performance of the proposed MR-MSA with the via were confirmed by the simulation and the measurement.
