Abstract

This paper presents a prototype design of antenna for Internet of Vehicle (IoV). Presented antennas is an array of 4 quarter-wavelength monopoles set in form of lozenge and on an infinite ground plan confused to vehicle’s roof. Monopoles are 2 by 2 linearly associated and are excited properly in magnitude and phase. Uzkov’s theory is first used to calculated appropriate excitation coefficients and after that Non-Foster circuit theory for determining an impedance-matched with a . Ansys HFSS is used for simulations and results show a good bandwidth and particulary a superdirectivity in order of 8.2 dB reconfigurable in a desired and useful direction.
