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.

A broadband omnidirectional horizontally polarized loop antenna comprising:
- a conductive antenna body including first and second opposing ends with a medial portion therebetween, the antenna body having a slot extending from at least adjacent the first end to at least adjacent the second end;
- the medial portion of the antenna body being wider than the opposing ends;
- and
- antenna feed points at the medial portion of the antenna body adjacent the slot.
A omnidirectional horizontally polarized antenna comprising:
- a conductive antenna body including first and second conical antenna elements each having an apex and a base opposite the apex, the bases being connected together to define a medial portion of the antenna body, and the antenna body having a dielectric slot extending from the apex of the first conical antenna element to the apex of the second conical antenna element;
- and
- antenna feed points at the medial portion of the antenna body adjacent the slot.
A method of making an omnidirectional horizontally polarized antenna comprising:
- forming a conductive antenna body including first and second conical antenna elements each having an apex and a base opposite the apex, the bases being connected together to define a medial portion therebetween, the medial portion of the antenna body being wider than the opposing ends;
- forming at least one dielectric slot extending from at least adjacent the apex of the first conical antenna element to the apex of the second conical antenna element;
- and
- connecting an antenna feed at feed points adjacent the at least one dielectric slot at the medial portion of the conductive antenna body.
