Abstract

A simple and accurate cavity model called the modified Wolff model (MWM) is presented to compute the resonance frequency and input impedance of the circular microstrip antenna on the PTFE, alumina, and GaAs substrates. Results of the MWM show better agreement with the experimental results as compared to results of the commercial software; namely, the standard cavity model adopted in the PCAAD, the multiport cavity model (MCM), and the method‐of‐moments– (MOM) based Ensemble. The MWM works with high accuracy on both the thin and thick substrates and from microwave to millimeter‐wave range. © 2002 Wiley Periodicals, Inc.

## Abstract Monopoles of 1‐mm axial length are designed and fabricated on silicon substrates of high‐resistivity 5 kΩ‐cm and low‐resistivity 10 Ω‐cm, respectively. We measure their performance up to 110 GHz for wireless interconnects for the first time. The reflection measurements show that a sharp
