The main goal for the CVIS1 project is to create a wireless network between vehicle and roadside infrastructure. CVIS includes implementation of technology components, to develop a multichannel terminal. This terminal will be installed in a vehicle, and in this paper we report on the development of the Rooftop Antenna Unit. The antenna unit contains 5 individual antennas, including two WLAN antennas. The WLAN antenna is a broadband double-fed printed monopole antenna designed and optimized within the CVIS project. It covers the frequency band 2.0-6.7 GHz, a bandwidth of 128%. The Rooftop Antenna Unit will be used for the CVIS field trials, taking place at six different test sites throughout Europe.Keywords: Monopole antenna; microstrip antennas; wideband antennas
