Two planar circular disc antennas that utilize compact impedance matching networks for current and future ultra-wideband (UWB) applications are investigated. The proposed designs have a physically small size (30 mm x 35 mm) and simple geometry, and offer a relatively large bandwidth (BW). Input energy is launched through a 50-Omega feedline (attached to a K-Connector) and broadband antenna matching is improved by introducing transitions between the feedline and the printed circular discs. Specifically, two designs are investigated using single- and duel-microstrip line transitions. By using this antenna matching technique, respective BWs (vertical bar S(11)vertical bar
