Abstract
According to various aspects, exemplary embodiments are provided of antenna assemblies. In one exemplary embodiment, an antenna assembly generally includes at least one antenna element having first and second electrical paths. The antenna assembly may also include at least one reflector element spaced-apart from the antenna element for reflecting electromagnetic waves generally towards the antenna element.
Claims24
An antenna assembly comprising:
- at least one antenna element including an upper portion, a lower portion, first and second side portions extending from the lower portion to the upper portion, an intermediate portion extending from the first side portion to the second side portion, the intermediate portion disposed generally between the upper and lower portions, and upper and lower openings respectively defined above and below the intermediate portion;
- a first electrical path defined by an outer loop of the antenna element including the upper portion, lower portion, and first and second side portions;
- a second electrical path shorter than the first electrical path, the second electrical path defined by an inner loop of the antenna element including the lower portion, intermediate portion, and corresponding segments of the first and second side portions disposed between the intermediate portion and the lower portion;
- and
- at least one reflector element spaced-apart from the antenna element for reflecting electromagnetic waves generally towards the antenna element,
- wherein the intermediate portion is closer to the upper portion than the lower portion.

An antenna element for reception of television signals within a bandwidth ranging from about 170 megahertz to about 216 megahertz, the antenna element comprising:
- first and second bottom members having respective first and second end portions;
- a top member;
- first and second side members extending upwardly from the respective first and second bottom member to the top member;
- a tuning bar extending from the first side member to the second side member;
- upper and lower openings respectively defined above and below the tuning bar;
- a first electrical path defined by the antenna element so as to include the first and second bottom members, the first and second side members, and the top member;
- a second electrical path shorter than the first electrical path, the second electrical path defined by the antenna element so as to include the first and second bottom members, the tuning bar, and corresponding portions of the first and second side members disposed between the tuning bar and the respective first and second bottom members,
- wherein the tuning bar is closer to the top member than the first and second bottom members.
