Firstly, copper is used there, the resistance of which is lower than that of iron, and secondly, textolite is able to withstand almost any weather conditions, which allows you to hang the antenna right on the street. However, we recommend using a board made of foil textolite for this.
HOMEMADE DOUBLE BIQUAD WIFI ANTENNA LICENSE
It can be made from anything at all: from the wall of a case from a computer, an old piece of iron lying around, a license plate number. Next, put aside the resonator in a groan and take on the reflector. The ends of the wire can be soldered together. The angle between the sides of the squares should be 90 degrees. See drawing for simplicity.Īs soon as you have one square, make a second one, as similar as possible to it, from the other end.
Make sure that deviations in different directions are minimal and the wire does not bend anywhere in the other direction. Then you have to take the pliers and bend the wire at a 90 degree angle at each notch. First, we take a piece of wire 244 mm long and mark it every 30.5 mm. We hope you have mastered the school geometry course well enough and know how a square should look. In addition to it, you may need a hammer, pliers, soldering iron, solder, ruler, rosin or soldering flux, preferably LTI-120, and hands growing from the right places. You can get it anywhere, because in our time it is not a shortage at all. For it, you will need a copper wire with a diameter of 1.5-3 mm.

For WiMAX, this means free Internet in the country. Some sources also report that if used in conjunction with a parabolic mirror (an ordinary satellite dish), then gain up to +20 dB can be achieved. This antenna is capable of giving gain from +6 to +10 dB.
Naturally, among radio amateurs this simple and affordable version of the antenna has been used for more than a year, and this system itself was invented a very long time ago. The resonator is itself a quarter-wavelength double square, while the reflector is the metal part to which everything is attached. The antenna consists of two parts: a reflector and a resonator. To create an antenna that performs the same over the entire frequency range, we will make the side of the square equal to 30.5 mm, which is a quarter-wave band. Let's just say that its length is approximately 124 mm at 2.4 GHz (beginning of the operating frequency) and 111 mm at the end of the range at 2.7 GHz. Let's not bother you with long calculations. It is enough to divide the speed of light in vacuum by the frequency of the wave. According to the formula from the physics course, it is quite simple to calculate it. To make an antenna, we need to know the wavelength. The difference lies in the encoding of the signal and the power of the transmitter, but for our antenna this is completely unimportant. The operating frequencies of Wi-Fi and WiMAX are absolutely identical and equal to 2.4-2.7 GHz. Today we want to offer you the design of a simple, inexpensive and reliable antenna, which can be assembled almost from scraps!
