planar slot antenna using Substrate Integrated Waveguide technology (SIW) is proposed in this paper. SIW has all the advantages required for a small size antenna package: Lowcost, high-performance and ease of integration. The SIW antenna with tapered microstrip-SIW transitions are integrated and synthesized on a single substrate. This structure is designed with Finite Element Method (FEM) using...

In this work, a probe fed microstrip antenna design for the implementation of two dimensional arrays with individually fed radiating elements is presented. The performance of the antenna element, both isolated and in a 4× 4 fixed array topology, is analysed using ADS and HFSS simulation software. Prototypes of the antenna element and of the array are manufactured and measured for the experiment...

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 ...

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...
