Patent attributes
A compact, broadband, aerodynamically streamlined, mechanically rugged antenna for aircraft and other applications has been developed that has a VSWR of 2:1 or better, and has uniform patterns with no nulls over a wide 8:1 bandwidth from 225 MHz to 1.85 GHz. The antenna has an aerodynamically streamlined shape, with a rugged housing capable of withstanding velocities up to Mach 2. In addition to its usage on aircraft, this antenna would be useful in a wide range of applications as a general purpose, wide bandwidth omnidirectional antenna. The antenna achieves its performance capabilities with the use of a double Vivaldi element feed section, an upper extension made of resistive film or R-card, and a shaped boundary between the feed and upper sections of the radiating elements.
