Biquad Construction

To take full advantage of MIMO (currently used in 4G LTE communications) two antennas must be used. When installing directional antennas like a panel antenna, the first antenna must be rotated horisontally to a 45 degree angle and the second to a 135 degree angle. This is because of "polarisation diversity". LTE uses polarisation diversity to help distinguish between the two data streams sent from the tower. This MIMO panel antenna for 3G has the advantage of good isolation between the two ports.

The radiant element is made on PCB this antenna is better than this...

Yes, this parasitic disc can be applied but only at helical antenna with 3...5 coils or at least reduced by 70-71%.!

,,,by Oveco ... When used with the WiFi adapter Alfa AWUS036H managed to keep the relationship at a distance of more than 10 nautical miles (18.5 km). Features Wi-Fi antennas AP-15m: * Operating frequency band: 2.4 GHz * Gain: 15 dB * Angle of the main lobe: 30\30 degrees * Weight: 0.75 kg * Dimensions (without mount): 20х20х2см * Crosspolarization: -30dB * Antenna efficiency: more than 90% * 2m cable included, SMA connector * The antenna has a swivel mount on the tube with the wing nuts
