This paper investigates the properties of the on-wafer coupled interconnects built in a 0.18μm CMOS technology for RF applications. A SPICE compatible equivalent circuit model is developed. The proposed model is an extension of a 2-Π equivalent circuit model for single-line interconnects by adding two coupling components. The model parameters are extracted from four-port S-parameter simulation ...

This paper describes the analysis and design of a class of square spiral microstrip antennas for broad frequency band and multi-frequency operations by adding suitable tuning elements in a single structure. The simulation and modeling of these configurations have been done using Ansoft HFSS software. The resonant frequencies and dimensions are computed from the cavity model of square patch. The...

The best way of gain enhancement can be obtained is from the array models, but there are some problems associated with array antennas. Mutual coupling losses, element spacing and design complexity are major concerns in the array antennas. The present paper deals with the performance characterization among the 2X2, 3X3, 4X4 array antennas. Rectangular patch array models are constructed and simul...

In this paper the behavioral study is presented on uniformly doped silicon substrate. Resistivity and thickness of substrate is varied and analyzed. It is observed that with the increase in resistivity and decrease in thickness of substrate, crosstalk problem existing in mixed circuits is reduced. FEM technology is used and HFSS simulation is done for S parameter extraction for 1000*1000*tμm2 s...
