ABSTRACT:
The biconical loop antenna is the dual and compliment to the biconical dipole antenna, and has broadband omnidirectional horizontally polarized radiation. The antenna includes a conductive antenna body having first and second opposing ends with a medial portion therebetween. The antenna body has a slot extending from at least adjacent the first end to at least adjacent the second end, and the medial portion of the antenna body is wider than the opposing ends. First and second body portions may be conical antenna elements connected together at their respective bases. Antenna feed points are at the medial and chine portion of the antenna body adjacent the slot.
