A low-profile and compact 3D antenna operating at LTE, GSM and UMTS frequency bands (790–2690 MHz) is proposed for a vehicular 2×2 MIMO system. The performance of the single 3D radiating element is here analyzed. Then, the two-antenna system performance is analyzed in terms of impedance matching, isolation and envelope correlation coefficient, highlighting the effect of some geometrical parameters...
A novel compact 3D antenna operating at LTE, GSM and UMTS frequency bands (790–2690 MHz) is proposed for vehicular applications. The antenna consists of a metal-sheet properly cut and shaped to fit an overall volume of 50×50×30 mm3. A Planar Inverted-F Antenna is designed to cover the lower frequency band (below 1GHz), while an integrated folded monopole adds higher frequency resonances. An elliptical-shape...
Two low-profile and compact 3D antennas operating at LTE, GSM and UMTS frequency bands (790-2690 MHz) are here numerically analyzed for a vehicular MIMO system. After an analysis of the single element performance, two identical 3D antennas are considered. A preliminary numerical analysis on the effect of geometrical parameters such as inter-element distance and reciprocal orientation have been discussed...
A novel ultra wideband antenna is here proposed for Vehicle to Infrastructure (V2I) communication systems. Two Vivaldi antennas are arranged in a back-to-back configuration (array of two Vivaldi antennas) to radiate both in front and rear car driving direction. By feeding the antennas with out-of-phase currents, the field radiation in the transversal direction is attenuated, so limiting the multipath...
A back-to-back Vivaldi Antenna is here proposed for a novel Vehicle to Infrastructure (V2I) communication system in the X-band (8.5–11GHz). The antenna has to be compact and low-profile in order to be installed on the car's roof. To cover the entire operating band, an ultra wideband (UWB) Vivaldi antenna has been chosen. Since the antenna has to radiate both in front and rear car driving direction,...
