CMOS antenna tuning unit for 2.4 GHz ISM band

Abstract
Antenna matching is improved with adaptive 0.35 μm CMOS circuits based on switched shunt capacitors arranged in capacitor banks and external series inductors. The simulated circuits are optimized for the ISM 2.4 GHz band. The circuits provide a VSWR ⩽ 2 match for every impedance with VSWR ⩽ 5. There is a 1 dB power loss for a perfect 50 Ω → 50 Ω transformation, a break-even point at VSWR = 1.5, and a 3dB increase in delivered power for VSWR = 4.3
