ABSTRACT:
An elliptic-shaped cylindrical antenna radiating element having a first side and a second side includes a first rectangular slot disposed in the first side and a second port disposed in the second side. A microstrip feed network located within the antenna radiating element radiates and receives horizontal polarized electromagnetic signals through the first slot and the second slot at a phase difference of about 180 degrees. The antenna radiating element radiates and receives horizontal polarized electromagnetic signals substantially omnidirectionally.
