[QUOTE="Rickideemus, post: 123417, member: 12677"]The plainly named "Antenna Company" is adding the third dimension to those fractal antennas you've been reading about. They have the superformula, and apparently a superpatent, on Supershaped Dielectric Resonator Antennas which add from 3 to 6 dB of gain to a typical WiFi network.
