Antenna assemblies with tapered loop antenna elements
According to various aspects, exemplary embodiments are provided of antenna assemblies. In an exemplary embodiment, an antenna assembly generally includes at least one antenna element configured to be operable for receiving high definition television signals. The antenna assembly may also include at least one reflector spaced-apart from the antenna element that is configured to be operable for reflecting electromagnetic waves generally towards the antenna element.
1. A high definition television antenna assembly configured for receiving high definition television signals and communicating the received high definition television signals to a television, the antenna assembly comprising at least one antenna element including one or more fastener holes and a printed circuit board including one or more fastener holes, wherein the printed circuit board is attached to the at least one antenna element by one or more mechanical fasteners, wherein:
the at least one antenna element includes a first antenna element and a second antenna element;
each said first and second antenna element includes first and second portions that are generally symmetric such that the first portion is a mirror-image of the second portion;
the first and second antenna elements are in a mirror-image relationship and/or cooperatively define a generally figure eight configuration having a closed shape; and
the one or more fastener holes of the printed circuit board are aligned with corresponding ones of the one or more fastener holes of the first and/or second antenna elements, such that each said individual mechanical fastener is inserted through corresponding aligned fastener holes of the printed circuit board and the first and/or second antenna elements.
2. The antenna assembly of claim 1 , wherein:
the printed circuit board includes a balun; and/or
the antenna assembly further comprises at least one reflector spaced-apart from the at least one antenna element and configured to be operable for reflecting electromagnetic waves generally towards the at least one antenna element.
3. The antenna assembly of claim 1 , wherein the first and second antenna elements include at least two spaced-apart portions each including at least one of the one or more fastener holes that are alignable with the one or more fastener holes of the printed circuit board, and wherein each said individual mechanical fastener is inserted through both a corresponding fastener hole of the first and second antenna elements and an aligned corresponding fastener hole of the printed circuit board.
4. The antenna assembly of claim 1 , wherein each of the first and second portions of the first and second antenna elements that are generally symmetric extends from a bottom of the corresponding one of the first and second antenna elements to a top of the corresponding one of the first or second antenna elements.
5. The antenna assembly of claim 1 , wherein the first antenna element is integral with the second antenna element such that the first and second antenna elements have a one-piece construction.
6. The antenna assembly of claim 1 , wherein each of the first and second antenna elements includes an opening, an inner periphery, and outer periphery that are circular, ovular, triangular, or rectangular.
7. The antenna assembly of claim 1 , wherein each of the first and second antenna elements includes a generally annular shape with an opening having a substantially closed shape.
8. The antenna assembly of claim 1 , wherein each said individual mechanical fastener is a single screw.
9. The antenna assembly of claim 1 , wherein the first and second antenna elements include first and second tapered loop antenna elements, respectively.
