As the demand for low-cost electronic systems increases, increasing wiring density/reducing printed circuit board (PCB) layer count becomes inevitable. This reality limits the PCB routing layer options of high-speed input/output (I/O) signals, making it more difficult to meet the next-generation product’s performance targets. For example, using densely wired microstrip routing on a PCB helps re...

The Matrix-Pencil (MP) method is applied to the estimation of the undesired radiation from the microstrip line discontinuities. The Q factors are obtained from the complex resonant frequencies estimated from FDTD transient field by using MP. The number of the damped oscillations is estimated by using MDL which is widely used as an information theoretic criterion for the model order estimation. ...

The investigations on a new proximity coupled dualfrequency microstrip antenna, which can be operated at GPS and Bluetooth frequency bands of wireless communication, are reported. The patch geometry consists of two square sections joined at the common corners and proximity coupled by a microstrip line. The results show that the antenna has sufficient bandwidth and gain necessary for the above f...

in this paper, a generalized method for accurate full-wave analysis of shielded mic's and the three-layer microstrip structure enclosed in a rectangular cavity based on mixed potential integral equation (mpie) derived in real space have been developed. method of moments (mom) with galerkin technique has been used for the solution of the integral equation to obtain the surface electric currents ...

In this work, a dynamic analysis of the V line is presented. Previous work analyzed the performance of this structure for low frequency applications using quasistatic approximations. Here, we extend the analysis of the V line into the higher frequency range where dispersion becomes significant and where it cannot be predicted by quasistatic methods. We show that the V line provides features and...

in this article, the linear array (with 20 elements in the horizontal orientation) of microstrip antenna is examined with horizontal polarization. the set includes three microstrip substrates. there is a power network in two lower substrates and microstrip patches in the upper substrate. excitation of patches has been done as coupled through the power network in two lower substrates. using the ...

Advanced numerical linear circuit models for parallel microstrip coupled line sections have been developed by Applied Wave Research (AWR) for use with their Microwave Office simulation program. The linear elements incorporate closedform solution techniques that may be evaluated with a linear circuit simulator. The response of the elements provides a high degree of accuracy with respect to elect...

This paper represents a novel second harmonic power combining oscillator using mutually synchronized Gunn diodes embedded on slot line resonators. A both-sided MIC technology is adopted in the oscillator. The oscillator consists of Gunn diodes, slot line resonators and microstrip lines. By embedding Gunn diodes on slot line resonators, desired harmonic RF signal can be generated very easily. Th...

This paper presents construction of a composite right/left-handed (CRLH) transmission line (TL) based bandpass filter using microstrip parallel coupled lines and hairpin lines. For getting high coupling in comparison to conventional edge coupled microstrip line, the floating slot on the ground plane is used. Two configuration named as SOS (short-open-short) the OSO (open-short-open) model are s...
