A Compact Planar Monopole Antenna for Ultra-wideband Operation

摘要

A novel planar monopole antenna of small dimensions is proposed for ultra-wideband (UWB) operation. With the use of a planar monopole microstrip feed and a subminiature version A (SMA) connector, the proposed antenna has a very wide impedance bandwidth from 3.06 to 10.80 GHz, defined by a VSWR less than 2:1. The transmission loss and group delay are also measured and discussed.
