Abstract
A low-profile multi-band antenna for telematics applications is described, where the antenna has multiple resonant frequencies. A single feed connects multiple transceivers to the antenna. The antenna has a height less than a centimeter and a surface area of around 60 square centimeters. The resonant frequencies of the antenna are determined by a center sub-patch and additional sub-patches that surround the center sub-patch. Ferrites, placed between the sub-patches and a ground plane, are used for tuning the resonant frequencies.
