Abstract: A multi-band antenna suitable for use by vehicles has ports for Wi-Fi and DSRC signals, cellular signals, and GPS signals. A base substrate forms a ground plane, and a shark-fin shaped radiating substrate is transversely aligned with the base substrate. On a first side of the radiating substrate there is a first conductive feed strip with a vertical extending portion that is galvanically connected to the first port, and a second conductive feed strip that is galvanically connected to the second port. On a second side of the radiating substrate there is a first wide-slot that is capacitively coupled to the first and second feed strips, is galvanically connected to the base conductor, and overlaps with at least the extending-portion of the first feed strip. There also is a second wide-slot on the second side that extends from a back edge to a location between the first and second ports.
