Abstract

Dual polarization in an antenna structure that results from a number of radiating elements arranged in a loop configuration. The antenna structure is excited by a single coaxial feedline in an interior portion of the antenna structure. The antenna structure may include a ground plane that enables a directional radiation pattern. The antenna structure may also be operational without a ground plane to enable an omnidirectional radiation pattern. The antenna structure may be configured in a number of loop configurations electrically connected to each other by a number of microstrip loops extending in a horizontal and vertical planar direction.
