Low‐profile tetra wire‐patch antenna for automotive applications

Abstract

A wire‐patch antenna operating over the terrestrial trunked radio emergency and public safety standard is presented. It exploits the use of shorting wires to operate below its fundamental cavity resonance mode. Thanks to low‐cost, low‐profile, solidity, ease of fabrication, and dipole‐like radiation pattern properties, it results to be particularly suitable for automotive applications. © 2012 Wiley Periodicals, Inc.

Simple antenna structure enabling the simultaneous excitation of two different polarisation and radiation modes

“…In comparison to a standard vertical dipole that would provide a similar omnidirectional radiation pattern, a size reduction of about 84% has been reached. This kind of radiation behaviour is obtained since the antenna basically operates like a wire-patch antenna [22,23] at this frequency. This is demonstrated by the surface currents distribution reported in Fig.…”
