Substrate Integrated Waveguide (SIW) ialah reka bentuk pemande gelombang yang terkini dalam teknologi gelombang mikro. Kini, permintaaan terhadap pemandu gelombang yang mempunyai kecekapan yang tinggi, telah melahirkan reka bentuk SIW. Sebenarnya SIW ialah pengubahsuaian pemandu gelombang segi empat tepat. SIW membolehkan integrasi dengan litar planar dipermudahkan selain daripada padat dan kos rendah. Dalam projek ini, SIW dengan peralihan tirus jalur mikro akan direkabentuk dan disimulasi dengan CST Studio Suite. Reka bentuk tersebut dinyatakan akan beroperasi dalam jalur Ku (12 – 18 GHz). Spefsifikasi reka bentuk ialah mod TE10 dan udara sebagai dielektrik Penentuan parameter seperti ketebalan dan diameter lubang, diperlukan sebelum reka bentuk dibuat dalam perisian. Ini memastikan bahawa reka bentuk menepati spesifikasinya. Simulasi reka bentuk diperlukan sebelum fabrikasi reka bentuk ke atas RO4003C. S- parameter yang diperoleh daripada hasil simulasi direkodkan untuk menjalankan teknik menyahterapkan pemandu gelombang kemudian. Model yang telah difabrikasi akan diuji dengan PNA-X NA N5245A dan peranti di bawah ujian akan diyahterapkan untuk mendapat ciri-cirinya. Teknik penyahterapan boleh dijalankan melalui dua cara, sama ada menggunakan kaedah matematik atau pelaksaan terus teknik di dalam NA. Menerusi project ini, lebih banyak pemahaman tentang pelaksaan teknik penyahterapan pemandu gelombang ke atas SIW dapat dicapai. Walaupun SIW diterapkan dalam sesebuah rangkaian, ciri-cirinya dapat mudah ditentukan dengan menggunakan teknik tersebut. ______________________________________________________________________________________ Substrate Integrated Waveguide (SIW) is the latest design of waveguide in microwave technology. Nowadays, the demand for waveguides with higher efficiency had implemented the design of SIW, which is indeed a modification of traditional rectangular waveguide. With the SIW, low cost, compact & easy integration with planar circuits can be achieved. In this project, a SIW with microstrip tapered transitions is to be designed and simulated using CST Studio Suite. The design is specified to operate for Ku band (12 – 18 GHz). The design specification is TE10 mode and with air dielectric. Determination of parameters, such as thickness, diameter of vias, and distance between adjacent vias is required before the design is made in the software. This is to ensure the design matches the specification. Simulation of design is required before the fabrication of design on Printing Circuit Board (PCB). S-parameters from the simulation results are recorded to perform waveguide de-embedding technique later. The fabricated model is then tested with PNA-X Network Analyser (NA) N5245A and DUT of the test fixture is de-embedded to determine its behaviour. There are two ways to perform de-embedding technique using NA, either via using mathematical method or direct implementation of the technique in NA. Through this project, a better understanding on implementation of waveguide de-embedding technique on SIW is achieved. Although SIW is embedded in a network, its behaviour can be easily determined using the technique.
