Here, we propose a novel route to realize arrays of 5.5-mm-long normal mode helical antennas operating in the industry-scientific-medical radio bands at 5.8 and 2.4 GHz, relying on a self ...

[Dereksgc] puts that reputation to the test by building a helical WiFi antenna — and if that weren’t enough — he also subjects it to a field test. In a real field, is there any other way?

Roccor has completed radio frequency testing of the helical L-band antenna ... Roccor and BluFlux faced an array of challenges in developing and testing an antenna large enough to communicate ...
