First Claim
Patent Images
1. A pulse-responsive dipole antenna, comprising:
- a first triangular element having a first base and a first apex opposite the first base; and
a second triangular element having a second base and a second apex opposite the second base;
wherein said first and second triangular elements are arranged with said first base generally adjacent and parallel to said second base, and with said first apex directed generally away from said second apex.

Abstract
A time domain communications system wherein a broadband of time-spaced signals, essentially monocycle-like signals, are derived from applying stepped-in-amplitude signals to a broadband antenna, for example, a reverse bicone antenna or a pulse-responsive dipole antenna. When received, the thus transmitted signals are multiplied by a D.C. replica of each transmitted signal and thereafter are successively short time and long time integrated to achieve detection.
