Compact planar hybrid ring coupler with embedded meander line

Compact planar hybrid ring coupler with embedded meander line / Mohd Hafiz Abd Halim
Penyambung hibrid boleh digunakan untuk menanggalkan dan meningkatkan pengasingan antara pelabuhan antena. Ia biasanya digunakan dalam aplikasi seperti rangkaian suapan antena, pembahagi kuasa, penggabungan, pengadun dan peralihan fasa digital. Dalam projek ini, ia memberi tumpuan kepada bagaimana untuk merancang coupler cincin hibrid planar padat dengan garis meander tertanam dengan menggunakan CST. Cadangan coupler cincin hibrid adalah kerana ia lebih baik dari segi kos pengeluaran yang rendah daripada teknik lain, kehilangan pulangan yang baik dan persembahan pengasingan dan mengurangkan kos. Oleh itu, ia boleh menjadikan peranti itu berfungsi dengan prestasi yang lebih baik. Dalam karya ini, ia tertumpu pada bagaimana untuk mengurangkan saiz coupler cincin hibrid supaya ia dapat memperoleh bacaan Parameter-S yang baik. Reka bentuk yang dicadangkan direka dengan menggunakan papan litar bercetak Rogers RO4003C dengan pemalar dielektrik 𝜀𝑟, 3.55 mm, ketebalan substrat, H, 0.81 mm dan ketebalan tembaga, t, 0.035 mm. Reka bentuk yang dicadangkan boleh dikendalikan pada 2.4 GHz. Hasil simulasi dianalisis dan dibandingkan secara teoritis dan praktikal supaya ia mencapai keperluan Parameter-S. _______________________________________________________________________________________________________ Hybrid coupler can be used to decouple and increase the isolation between antenna ports. It is normally used in applications such as antenna feed networks, power dividers, combiners, mixers and digital phase shifters. In this project, it is focuses on how to design compact planar hybrid ring coupler with embedded meander line by using CST. The proposed of hybrid ring coupler is because it have better in terms of low production cost than other techniques, good return loss and isolation performances and reduce the cost. Thus, it can makes the device to perform with better performance. In this work, it is mainly focused on how to reduce the size of hybrid ring coupler so that it will obtain good S-Parameters readings. The proposed design is fabricated using Rogers RO4003C printed circuit board with dielectric constant of 𝜀𝑟, 3.55 mm, thickness of substrate, H, 0.81 mm and thickness of copper, t, 0.035 mm. The proposed design can be operated at 2.4 GHz. The simulation result were analyzed and compared theoretically and practically so that it achieve the requirement of S-Parameter.
