Abstract :
The design and measurement of a compact narrowband impedance matching network is presented. The device has been realised in hybrid technology: coplanar waveguide transmission lines and surface-mounted components. The experimental results were carried out through two different measurement methods, a traditional approach and a new faster, simpler one giving the same results. They show that complex impedances with magnitudes varying from 6.3 to 1120 Omega can be matched with a 50% bandwidth around the centre frequency.
