First Claim
Patent Images
1. A bidirectional broadband log-periodic antenna assembly having a comparatively small physical size, the antenna assembly comprising:
- a) a printed wiring board having front and back sides;
b) a plurality of log-periodic antennas etched upon at least one side of the printed wiring board, each log-periodic antenna comprising a plurality of antenna elements extending from a common trunk, the trunk of each log-periodic antenna extending generally radially from a common point; and
c) a resistive film formed upon a distal end of a longest antenna element extending from at least one trunk, the resistive film enhancing a low frequency response of the antenna assembly.

Abstract
A bidirectional broadband log-periodic antenna assembly has a printed wiring board having a plurality of log-periodic antennas etched upon at least one side thereof. Each log-periodic antenna comprises a plurality of antenna elements extending from a common trunk. A resistive film is formed upon a distal end of a longest antenna element extending from at least one trunk. The resistive film enhances a low frequency response of the antenna.
