IntroductionThis is basic instructions for handmade WiFi 5-5.8 GHz 13-14dBi Double BiQuad external antenna.Note: The dBi scale is logarithmic in base 10, where +3 dBi is a doubling in gain! An increase in gain of +1 dBi is equivalent to an increase of 26% and +2 dBi is equivalent to an increase of 60%. This means that the increase in +1dBi is a big deal.I used computer software (antenna modeler and optimizer) version 5.8.11 to model theoretically the perfect antenna. All measurements based on very careful analysis with computer software which results many times has been proven to be quite accurate and reliable in physical world.5 - 5.8 GHz is fairly wide frequency range so I calculated 6 antennas for 6 diff. Frequencies: 5200, 5300, 5500, 5580, 5700, 5805 MHz and found out that all parameters is quite the same, so instead of dozen antennas for every channel I would recommend single based on average calculations from six simulations.
Hence here's a guide.(Simulation parameters for six antennas and averages)Description. ( Very important to choose proper cable! the longerthe cable length, the more signal loss you'll have through the cable. Long cable will defeat the purpose of the antenna. Read the guide for more info.). 30 cm length of copper wire for the element.
1 mm in diameter. Wider is not recommended. Spacers in each end of the element to hold its position and spacingcorrect height between the radiator and the reflector.
