Abstract: An antenna assembly includes a phased array antenna having an array of spaced apart antenna elements arranged on a horizontal surface and having an axis of symmetry, and a lens disposed on the phased array antenna. The lens substantially covers the antenna elements. The lens includes a substantially planar bottom surface. The bottom surface and tops of the antenna elements define a gap therebetween. For a second vertical plane orthogonal to the horizontal surface and including the axis of symmetry. the antenna assembly steers a beam in a second vertical plane having a 3 dB beam width W1 when steered along a first direction making an angle of less than 10 degrees with a normal to the horizontal surface and a 3 dB beam width W2 when steered along a second direction making an angle of greater than 40 degrees with the normal. W1 and W2 within 35% of each other.
