Abstract: An endfire monopole array in a low cross section, low profile package with the area used being vertical or tube-like. The array is aerodynamically shaped on one or more sides in order to minimize wind resistance. The antenna array includes an RF transparent housing having a tapered end portion which is substantially "V" shaped, a first plurality of parallel endfire monopole antenna elements secured to a stripline or microstrip within the housing, each antenna element thereof extending in a first direction and a second plurality of parallel endfire monopole antenna elements secured to a stripline or microstrip within the housing, each antenna elements of the second plurality extending in the first direction, the first plurality being spaced from the second plurality in the first direction. An energy feeding structure is coupled to the antenna elements, with a dielectric layer disposed over that structure and a ground plane disposed over the dielectric layer.
