ANTENNA ASSEMBLIES WITH ANTENNA ELEMENTS AND REFLECTORS
First Claim
1. An antenna element configured for operating within a bandwidth ranging from about 470 megahertz to about 690 megahertz, the antenna element comprising:
- spaced-apart first and second end portions;
a middle portion; and
first and second curved portions extending from the respective first and second end portions to the middle portion such that the antenna element has a generally circular annular shape with a generally circular opening;
the first and second curved portions gradually increasing in width from the respective first and second end portions to the middle portion such that the middle portion is wider than the first and second end portions and such that an outer diameter of the antenna element is offset from a diameter of the generally circular opening;
the first curved portion being a mirror image of the second curved portion.

Abstract
According to various aspects, exemplary embodiments are provided of antenna assemblies. In an exemplary embodiment, an antenna assembly generally includes at least one tapered loop antenna element having a generally annular shape with an opening. An antenna assembly may also include a rotatably convertible support including a base and an upper portion coupled to a tapered loop antenna element in some embodiments. The upper portion is rotatable relative to the base between a first configuration for supporting the tapered loop antenna element on a horizontal surface and a second configuration for supporting the tapered loop antenna element from a vertical surface.
