Network model of coupled integrated antennas

Abstract

In this paper we propose a broadband equivalent circuit model of coupled integrated antennas using a generalized Foster approach. A largesignal multi-harmonic X-parameter model representation of On-Chip Schottky Diodes is derived for effective Antenna-Detector Co-Simulation, Co-Design and Co-Verification. Concurrent optimization of the Schottky Diode arrays geometry and large-signal electrical performances (such as with respect to cutoff frequency, parasitics, quality-factor, sensitivity, responsiveness, etc.) is carried out based on careful experimental characterizations.

Brune lumped element multiport modeling of MMMICs

“…For a linear reciprocal lossless multiport an equivalent circuit model may be established on basis of the canonical Foster representation [4,5]. For lossy circuits the Foster equivalent model can be extended by augmenting the equivalent circuit with resistors [6,7]. However, this augmented Foster circuits may exhibit negative element values which may give rise to instabilities [8].…”
