You can also use a real satellite dish and place the cantenna at the end of the arm at the position the TV antennas (the horn) usually go. You can then make a wooden or aluminum frame to hold everything together in the right position.

You can find formulas for calculating the exact focal point or use trial and error since you will see your signal gain double or even triple when you get the curve and distance just right. The article states ' The typical gain for this kind of antenna in the 2.4 GHz Wi-Fi band is about 10 dB.', but without a reference (usually dBi or dBd), that is a useless. It takes a bit of adjusting to get the curve of the screen and distance to the can exactly right. 'Cantenna calculator' must be changed to 'Cantenna calculator (2.4 GHz)' -lgoncalv 11 October 2009 Preceding undated comment added 03:19, 18 October 2009 (UTC). Instead of pointing the can at the signal source, point it at your screen which points at the signal so the back of the can points at the signal. To improve the signal even more - much more - cut a 2 foot (0.6 m) wide by 1 foot (0.3 m) high sheet of concrete lathing screen with 1⁄ 4 inch (0.6 cm) or smaller holes and curve it slightly to form a parabolic dish, similar to a TV satellite dish. This should be much stronger than the whip antenna you had before. dBm to Watt converter Stripline Impedance calculator Microstrip line impedance Noise temp.Aim at source and adjust to get the best signal.

Parabolic Dish Calculator Horn Antenna Calculator Dipole Antenna Calculator Patch Antenna Calculator Antenna near field calculator Antenna gain calculator Antenna G/T ratio calculator Useful converters and calculatorsįollowing is the list of useful converters and calculators. This 3-element Yagi Antenna calculator is useful to design the Yagi Antenna. Reflector to Dipole Spacing = 0.1875 meters,ĭipole to Director Spacing = 0.1875 metersįormula/Equations used in Yagi Antenna Calculatorįollowing formula/equations are used in the Yagi Antenna Calculator. OUTPUTS: Reflector Length = 0.7425 meters, Dipole Length = 0.7095 meters, Front to Back Ratio Yagi Antenna CalculatorĮXAMPLE of 3 element Yagi Antenna calculator:.The following are the basic specifications considered in selecting Yagi Antenna and performing calculations The spacing also depend on bandwidth, gain, F/B ratio and sidelobe pattern The spacing of reflector from driven element The length is usually 5% more compare to driven element. Reflector: It is placed at rear of dipole or driven element. The Gain of Yagi Antenna depends on length of antenna array and do not depend on number of directors used The spacing between directors usually range from 0.1λ to 0.5λ or more. It helps to achieve desired gain and directional pattern. It has resonant higher compare to driven element. It has length which is 5% short compare to driven element. Is about half of wavelength of frequency.ĭirector: It is designed mainly for receiving EM waves. It becomes resonant when its electrical length The feed point is located at the center of the driven element. This helps in transfer of energy from transmitter module to antenna. Driven Element): It is the feed point where feedline is usually attached from transmitter. It may have one or multiple directors.ĭipole (i.e. The simple Yagi Antenna is shown in the figure-1. The calculators for other antenna types such as parabolic,horn,dipole and patch are also mentioned. The formula and basics of Yagi Antenna Calculator are also explained with example.
