Ultra-thin, flexible, broadband low profile planar wire antenna

摘要

A broadband, low profile, ultra-thin and flexible, planar wire antenna includes an inverted triangular section and a horizontal bar section centered at the apex of the triangular section. Tab elements are provided on opposite ends of the bar section to increase the end effect of the antenna. Furthermore, 45 degree tabbed elements are joined to the top corners of the triangular section and extend in opposite directions therefrom. The tabbed elements added to the triangular section and to the bar section increase the overall electrical length of the antenna to simulate a physically larger size antenna.

1. A broadband low profile planar wire antenna, which comprises:
an inverted triangular section having outer sloping sides and an apex at least partially defined by the outer sloping sides, the inverted triangular section having an interior area; and an elongated bar section centered in proximity to the apex of the inverted triangular section, the elongated bar section being formed as an elongated member having a first axial end and a second axial end situated opposite the first axial end; wherein the inverted triangular section includes, as antenna elements: a first outer segment and a second outer segment, the first and second outer segments defining the outer sloping sides of the inverted triangular section, each of the first outer segment and the second outer segment being an elongated member and having a proximate end and a distal end situated axially opposite the proximate end of the respective first and second outer segments, the first and second outer segments mutually converging in a direction toward the proximate ends thereof such that the proximate ends of the first and second outer segments are electrically coupled together at the apex of the inverted triangular section; a base segment, the base segment being situated on the inverted triangular section opposite the apex of the inverted triangular section, the base segment being an elongated member and having a center portion, a first axial end and a second axial end situated opposite the first axial end of the base segment, the first axial end of the base segment being in electrical communication with the distal end of the first outer segment, and the opposite second axial end of the base segment being in electrical communication with the distal end of the second outer segment, the first axial end of the base segment at least partially defining a first corner of the inverted triangular section of the antenna, and the second axial end of the base segment at least partially defining a second corner of the inverted triangular section of the antenna; and at least a first tab segment and a second tab segment situated in proximity respectively to the first corner and the second corner of the inverted triangular section of the antenna, the at least first tab element and the second tab element being provided to help increase the effective electrical length of the antenna.
