ANTENNA ASSEMBLIES INCLUDING ANTENNA ELEMENTS WITH DIELECTRIC FOR FORMING CLOSED BOW TIE SHAPES

Antennas Direct, Inc., E...

1. An antenna assembly operable for receiving digital television signals, the antenna assembly comprising:
an antenna support;
at least one bow tie antenna coupled to the antenna support; and
at least one reflector coupled to the antenna support and disposed relative to the at least one bow tie antenna for reflecting
electromagnetic waves generally towards the at least one bow tie antenna;

wherein the at least one bow tie antenna comprises at least one pair of bow tie antennas spaced apart from each other;
wherein the antenna assembly further comprises a balun and one or more pairs of electrical conductors electrically connecting
the balun and the bow tie antennas; and

wherein:
the balun is electrically equidistant from the bow tie antennas such that the bow tie antennas are in phase; and/or
the one or more pairs of electrical conductors form a parallel wire transmission structure;
wherein the at least one bow tie antenna comprises a first pair of bow tie antennas coupled to the antenna support and spaced
apart from each other, and a second pair of bow tie antennas coupled to the antenna support and spaced apart from each other,
and wherein the antenna assembly further comprises:

a first reflector behind the first pair of bow tie antennas for reflecting electromagnetic waves generally towards the first
pair of bow tie antennas; and

a second reflector behind the second pair of bow tie antennas for reflecting electromagnetic waves generally towards the second
pair of bow tie antennas.

a printed circuit board having one or more fastener holes;
wherein the at least one antenna element includes one or more fastener holes; and
wherein the printed circuit board is attached to the at least one antenna element by one or more mechanical fasteners, each said individual mechanical fastener inserted through both a corresponding one of the one or more fastener holes of the at least one antenna element and a corresponding one of the one or more fastener holes of the printed circuit board aligned with the one or more fastener holes of the at least one antenna element;
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;
each said first and second antenna element includes a generally annular shape with an opening;
the first and second antenna elements positioned in a mirror-image relationship generally side-by-side in a generally figure eight configuration having a closed shape; and
the one or more fastener holes of the first antenna element overlap and are aligned with corresponding ones of the one or more fastener holes of the second antenna element, such that each said individual mechanical fastener is inserted through corresponding aligned fastener holes of each of the first and second antenna elements.
