Abstract
An antenna apparatus has a first wire-like antenna element formed into a rectangular planar loop and a second antenna element which comprises two L-shaped plates electrically connected to the loop and mounted to a rectangular planar base member. The loop is hinged to the planar base member along long sides of the respective rectangles so that the angle between the planes of the loop and base member is adjustable. The base member pivots about an axis on a mount which can be secured to a television receiver.
Claims16
An antenna apparatus comprising:
- a multi-dimensional first antenna element comprised of a wire formed into a loop in a first plane, said loop being generally in the form of a rectangle with the ends of said wire having a gap therebetween along one long side of said rectangle;
- a multi-dimensional second antenna element comprised of a plurality of plate members disposed in a second plane and including at least two L-shaped plates with the ends of one legs of said plates in mutually facing relationship and the ends of the other legs of said plates facing said one long side of said rectangle of the loop;
- means for mounting said first and second antenna elements rotatably with respect to each other for adjustment of an angle between said first and second antenna elements, the long side of said rectangle loop having said gap being rotatably mounted in respect to said second antenna element;
- and
- connecting means for electrically connecting said first and second antenna elements.
The antenna apparatus as in claim. 12;
- wherein said fixing means comprises cooperating face gears on said mount and said base member.
A compact antenna apparatus for use as an indoor antenna for a television receiver, the antenna apparatus comprising:
- a first planar antenna element comprising a conductive wire formed into a rectangular loop;
- a planar rectangular plastic base member;
- a second planar antenna element comprising a pair of plates secured to said base member in the plane thereof and electrically connected to said loop to form a VHF antenna therewith;
- a third planar antenna element comprising a pair of plates secured to said base member in the plane thereof to form a UHF antenna;
- matching circuit means secured to said base member for matching the impedance of said VHF and UHF antennas to leads from the television receiver for the signals received thereby;
- hinge means rotatably connecting a long side of said loop to a long side of said base member for adjustment of the included angle between the planes of said loop and base member;
- and
- mounting means for rotatably mounting said base member to the television receiver.
