Dual-multilayer PIFA for wideband signals

This paper presents the results of the design and realization of a compact antenna for the wireless transmission and reception of multifrequency signal with wideband characteristics. The intended use, although not exclusive, is in a station placed on a car, to receive and transmit data to and from a set of sensors placed in the interior of a tire, carrying information on the status of some tire parameters. The frequency bands in use are those of ISM (2.4-2.48 GHz) and part of the UWB (4.25-4.75 GHz). However, the antenna can be used in any other communication system with multifrequency characteristics, with appropriate modification of the dimensions in case of different operating frequencies
