“…The use of these resonators, either in propagative [8] or in evanescent mode [9], [10] topologies, provides a reduction of around 50% in mass and volume [8], [9], an increase of thermal stability [11], [12], and, if the dielectric rods are all inductive or H plane, an increase of out-of-band rejection and better field distribution (lower voltage magnification factor), because the peaks of electric field within these filters are concentrated inside the dielectric posts, thus producing a smaller level of electromagnetic field, outside the dielectric posts, than in the case of the all metallic filters [13]. Considering that the multipactor effect can only occur outside the posts, since inside the all inductive dielectric posts breakdown processes would require significantly much more power, it follows that these filters need more power for the multipactor discharge to take place.…”

The paper presents a RF performance comparison between several H plane geometry filters based on rectangular waveguide technology. The basic all metal filter of resonant cavities is compared to filters loaded with circular dielectric resonators, either in propagative or evanescent mode. The use of these resonators is claimed to reduce the length of the filter, increase the rejection band until the first spurious frequency and to improve the voltage magnification factor (VMF), at the cost of increasing the losses. So, in order to properly asses and quantify the possible advantages of these filters, an accurate analysis of six of them has been developed. All the filters have been designed to have the same electrical response, and the length, losses, rejection band, VMF and fabrication cost for all the filters are compared.

“…These parameters are the spacing between the adjacent resonators and I6 O feed line tap positions [25,26]. Parametric study to explore the effects of values of these parameters on the resulting filter performance will lead to minimum insertion loss and maximum return loss at the design frequency.…”

The proposed microstrip bandpass filters in this paper have compact sizes and narrow band responses which are the requirements of modern wireless communication circuits. These filters are constructed from dual-edge coupled resonators; each resonator is based on applying step impedance resonator generator on first and second iteration of Hilbert fractal resonators on each segment of each iteration level. They have been designed for the industrial, scientific, and medical band (ISM) band applications at a centre frequency of 2.4 GHz using a substrate with a dielectric coefficient of 9.6 and thickness of 0.508 mm. The performance of bandpass filters has been analysed using a method of moments (MoM) based on software package, Microwave Office 2009, from Advanced Wave Research Inc., which is widely adopted in microwave research and industry. Simulation responses show that these filters possess good frequency response characteristics with second harmonics suppression. Moreover, these filters showed noticeable miniaturization which is an important feature for many communication applications. The simulated and measured results are in good agreement.

AbstrakRiset bandpass filter telah mengalami perjalanan panjang, seiring dengan perkembangan teknologi wireless dan aplikasi sensor serta radar. Sampai dengan pertengahan 2015 ditemukan sangat banyak riset tentang bandpass filter di pelbagai publikasi yang ada. Dasar perancangan bandpass filter didominasi dengan metoda insertion loss yang menggunakan aproksimasi Butterworth, Chebyshev dan Elliptis. Realisasi dari elemen yang muncul dari aproksimasi di atas diimplementasikan dalam bentuk penggandengan beberapa resonator. PENDAHULUANPerkembangan teknologi nirkabel (wireless) didorong oleh tuntutan kebutuhan data rate yang tinggi dan fleksibilitas dari gerakan pasangan komunikasi yang menggunakannya. Gelombang elektromagnetika yang memiliki nilai frekuensi pembawa yang berbeda-beda, tergantung dari frequency assignment yang diberikan kepadanya, tercampur di saluran nirkabel ini (udara bebas). Perangkat pemancar dan penerima yang saling berkomunikasi satu sama lain, harus mampu untuk menyeleksi dan memilih gelombang elektromagnetika dengna frekuensi apa yang mereka pertukarkan. Bandpass filter adalah piranti yang melakukan tugas memilih sinyal yang diinginkan dari tidak diinginkan berdasarkan frekuensinya. Sinyal yang diinginkan dilewatkan oleh piranti ini dengan sebaik mungkin (tanpa kerugian), sedangkan sinyal yang tidak diinginkan, ditolak untuk melewati piranti filter ini.Teknologi filter telah berkembang cukup lama, dari penggunakan filter pada
