This letter discusses an experimental study and Hankel‐domain analysis of annular ring patch antennas attached to a laminated glass vehicle windscreen. The fundamental TM 11 and higher‐order TM 21 modes are studied, the latter being of interest for mobile satellite communications. Attaching the antenna to the screen brings about a doubling in the bandwidth, and adding a resistive ring on top of the screen further improves the bandwidth. ©1996 John Wiley & Sons, Inc.
