Abstract
A reduced height automotive antenna covering the three mobile telephone bands used around the world is described. The antenna is much more compact than a conventional monopole and is printed on a PCB for low-cost production. Circuit components are used to tune the antenna to cover the regional band variations for mobile telephone systems, enabling one design to cover them all. A voltage standing-wave ratio of better than 2 : 1 is achieved. Performance when used as a roof mount automotive antenna is close to that of a quarter-wave monopole antenna.
