Abstract
An omni-directional antenna can include a feed disk, which can terminate at a feed disk apex, and a top element, which can include a nipple that terminates a top element apex. The feed disk and top element can be positioned so that the feed disk apex and the top element apex can be spaced-apart by a distance “d”, which can be chosen according to the desired frequency range and cable feed impedance. The feed disk and top element can also have respective bottom conical and top conical surfaces. When the feed disk and top element are positioned, the top and bottom conical surfaces can establish a respective first predefined angle relative to a horizontal plane and a second predefined angle relative to the horizontal plane, thereby extending the antenna frequency range. The predefined angles can be chosen according to the desired frequency range of operation and cable feed impedance.
