1. A television broadcast signal receiving antenna structure, which comprises:
- a vase antenna housing, the vase antenna housing having a generally hourglass shape and including a generally conically-shaped lower segment, a generally conically-shaped upper segment mounted on and joined to the generally conically-shaped lower segment, each of the upper segment and lower segment having relatively larger and smaller diameter portions, the relatively smaller diameter portions of the upper and lower segments being joined together to define the generally hourglass-shaped vase antenna housing with one of a centered and off-centered relatively narrower diameter middle portion, the generally hourglass-shaped vase antenna housing having at least one of an inner surface and an outer surface extending in a longitudinal direction; and
a signal receiving antenna, the signal receiving antenna being situated on the at least one of the inner surface and the outer surface of the vase antenna housing and thereby conforming to the shape thereof to exhibit an arcuate, partial hourglass shape.

Abstract
An antenna structure for receiving digital television broadcast signals includes a vase antenna housing having a generally hourglass shape with conically-shaped upper and lower segments joined together to define a narrower diameter middle portion. The antenna structure further includes a signal receiving antenna etched on the inner surface of the vase antenna housing. The signal receiving antenna conforms to the shape of the vase antenna housing and thereby exhibits an arcuate, partial hourglass shape. The signal receiving antenna may be a cloverleaf antenna or a spiral antenna.
