The microstrip line is widely used as the planar transmission line in microwave integrated circuits and high speed interconnecting buses. In this paper, we use COMSOL multiphysics to study multiconductor microstrip systems on microwave integrated circuits. We specifically illustrate the modeling of open four and five conductors systems. We successfully demonstrated the calculation of the capaci...

This paper presents semicircular microstrip low pass filter with the sharp rejection and wide stop band. The proposed filter design is based on the calculations of filter parameters from traditional Hi-Lo impedance method and is available in the literature of microstrip filter. To further improve the design performance, high impedance lines are magnetically coupled, resulting an attenuation pol...

A single stage quadrature hybrid coupler with enhanced flat balance over a wide bandwidth is presented in this article. The present coupler is realized by replacing the transmission line sections of the conventional two-branch coupler by their equivalent parallel coupled microstrip lines (PCML). The impedance controlled wide-bandpass response produced by the PCML is utilized to achieve flat bal...

In this paper, a compact high-pass filter (HPF) with a sharp rejection response based on the balanced composite right-left handed (CRLH) transmission line (TL) concept is proposed. A series LC resonator using an interdigital capacitor and meander lines is designed. Also, a meander spiral complementary split ring resonator (MSCSRR) is used to realize the parallel LC resonator. The high-pass filt...

Novel microstrip dual-band bandpass filters with controllable fractional bandwidths and good in-between isolation are presented and implemented. A half-wavelength stepped-impedance resonator is firstly characterized, aiming at producing the two resonant frequencies at 2.4 and 5.2 GHz. Two types of coupled microstrip lines in the parallel and anti-parallel formats are then investigated in terms ...

Conventional PCB processing of organic dielectrics has been proven to be a very economical interconnect solution for a variety of PCB, module, and packaging applications in the telecommunications and computing markets. Organic microvia dielectrics are well suited for mobile wireless as well as telecom and computing infrastructure products where the latest fabrication techniques, such as high-sp...

We report the effect of a thick nitride layer on transmission loss in GaN-on-3C-SiC/low resistivity Si (LR-Si). Microstrip lines finite length and width with ground pads were fabricated three GaN-on-3C-SiC/LR-Si epitaxial structures varying thicknesses 3.2, 5.3, 8.0µm. The performance microstrip different substrates was evaluated frequency range 0.1 to 9GHz. sample 8.0µm showed minimal 0.3dB/mm...
