A low profile, planar, wide band (e.g., 600 MHz to 5 GHZ) antenna assembly consisting of four subarrays, each subarray consisting of a set of planar elements connected in a dipole. The elements may be disposed on a first layer or surface of a non-conductive substrate such as a printed circuit board. A second set of subarrays may also comprise planar elements disposed on a second layer of the substrate and operates as a GPS antenna. The elements on the second layer overlap somewhat with the elements on the first layer to provide a partial ground plane for the elements on the first later. A beamforming circuit may be coupled to the sub-arrays, depending on configuration. The assembly may be placed on a windshield or rear window of a vehicle, such as a passenger car near the roof.
