Rancang bangun microwave power amplifier dengan memakai saluran coplanar waveguide

" Antena aktif yang merupakan integrasi antara antena gelombang mikro dengan perangkat aktif seperti amplifier telah mendapat perhatian yang luas pada beberapa tahun belakangan ini. Pada umumnya, penempatan elemen aktif yaitu transistor microwave dalam rangkaian terintegrasi microwave (Microwave Integrated Circuit, MIC) dibuat pada saluran transmisi microstrip. Pada tesis ini dibahas mengenai rancangan microwave power amplifier sebagai elemen aktif dari antena yang dibuat dengan memakai rangkaian penyesuai saluran transmisi coplanar waveguide. Keuntungan utama yang diharapkan dapat diperoleh ... "

Emission and performance characteristics of waste cooking oil biodiesel blends in a single direct injection diesel engine

" The use of Waste Cooking Oil (WCO) as feedstock, and microwave heating technology are favored to reduce the cost of biodiesel. In order to identify the effect of using biodiesel from WCO Methyl Ester (WCOME) blends on diesel engine emissions and performance, WCOME blends were tested in a single-cylinder Direct Injection (DI) diesel engine at a constant speed of 2500 rpm and with five loads. For comparison, commercial diesel fuel, Petron Diesel Max (PDM), and ... "

High-performance radiation design of a planar bow-tie antenna combined with a dielectric lens and cascaded matching layers at terahertz frequencies

" The demand for high-speed data transmission has increased significantly in the last decades. Terahertz (THz) frequency, which lies between 100 GHz to 10 THz, has been considered as the solution to the demand. However, the low gain and low efficiency of a THz antenna remain to be issues that hinder reasonable performance for various applications. This paper proposes the design of a high-gain and high-efficiency planar bow-tie antenna for applications in the THz frequency. A ... "
