S11 · VSWR · matching network design
Overview
Designing impedance matching networks to achieve maximum power transfer from the feed system to the antenna element — optimising S11, VSWR, and return loss over the target operating band for single-band, multi-band, and wideband antenna systems.
Deliverables
Key Aspects
Characterising antenna input impedance as a function of frequency using full-wave simulation, generating broadband impedance data for matching network synthesis and system integration.
Designing L-network, T-network, PI-network, and transmission line matching topologies to transform antenna impedance to system impedance (50 Ω) across the target frequency band.
Developing matching networks that simultaneously cover multiple operating bands — 4G/5G, GNSS, Wi-Fi, Bluetooth — without requiring switched matching, maintaining compact PCB footprint.
Evaluating tunable matching networks using RF switches and varactors for adaptive antenna impedance control in reconfigurable radio systems and handset designs with body-loading effects.
