Patent ID: 8779998

Claim:
A wideband horizontally polarized antenna, comprising: a metallic antenna housing having four sides; only one hourglass-shaped slot positioned in each side of said four sides, wherein each said slot is one wavelength long at a center frequency of a selected operating frequency band, each said slot has a first side, a second opposing side, and two ends, and wherein each said side of said four sides of said metallic antenna housing has a face and a center of said face; a coaxial transmission or feed line positioned along a central axis of the metallic antenna housing; and a metal tab connecting each of said first side of each said slot to the feed line, whereby when the antenna is powered up each of said slots is excited only on each said first side with each said second opposing side floating, thereby establishing a horizontally polarized electric field in each said slot between each metal tab from the feed line and each floating side such that an electric field travels away from the center of each said slot to the ends and radiates a horizontally polarized field.
