A multiband multiple input multiple output (MIMO) vehicular antenna assembly having multiple cellular antennas (104, 108) with low correlation therebetween for receiving communication signals within one or more cellular frequency bands, the antenna assembly comprising: a first cellular antenna configured to be operable for receiving and transmitting communication signals within one or more cellular frequency bands; a second cellular antenna configured to be operable for receiving communication signals within one or more cellular frequency bands; and one or more satellite antennas (112, 116) configured to be operable for receiving satellite signals; the first cellular antenna comprises a monopole antenna; the second cellular antenna comprises an inverted F antenna, including: a planar surface; and a downwardly extending portion generally perpendicular to the planar surface and operable for electrically connecting the second cellular antenna to a ground plane; the one or more satellite antennas (112,116) comprise a first patch antenna configured to be operable for receiving satellite signals, and a second patch antenna configured to be operable for receiving satellite signals different than the satellite signals received by the first patch antenna; the antenna assembly. further comprises a chassis supporting the monopole antenna, the inverted F antenna, and the first and second patch antennas, and a radome coupled to the chassis such that the monopole antenna, the inverted antenna, and the first and second patch antennas are enclosed within an interior space defined by the radome and the chassis; and the antenna assembly is configured to be installed and fixedly mounted to a vehicle body wall after being inserted into a mounting hole in the vehicle body wall from an external side of the vehicle and nipped from the interior compartment side, characterized in that: the planar surface of the inverted F-antenna has a through hole; the inverted F-antenna includes a generally L-shaped extension connected to an edge of the planar surface and that defines an opening; the first patch antenna is positioned at least partially through the opening of the second cellular antenna; a first connector extends through the first patch antenna to electrically connect to a first printed circuit board; the second patch antenna is disposed or mounted on the planar surface of the second cellular antenna; and a second connector extends through the second patch antenna and the through hole of the second cellular antenna to electrically connect to a second printed circuit board; the antenna assembly is configured such that the isolation between the first and second cellular antennas is at least about 15 decibels and the correlation is less than about 25 percent between the first and second cellular antennas. a first cellular antenna configured to be operable for receiving and transmitting communication signals within one or more cellular frequency bands;
