Antenna Power Devider

This Power Divider Combiner not only use for dividing or combining RF power on RF amplifier constructions, but also use in dividing RF power if you use more than one antenna for higher gain.

The Construction of simple power divider combiner with the equation below :
Z = 1.38 x log (1.08 x (D/d)) for square tube

Where,

• D = The Inner Width of the tube
• d = The Outer Diameter (OD) of the inner conductor
• Z = Impedance

The Equation of Impedance Approach :

Z = 1.38 x log (1.08 x (D/d))

Z = 35.88 Ohms

Pict : Example for 2.4 Ghz

• A = Chasis mount N Jacks
• B = Solder the N center connectors pins directly to the inner of the copper conductor
• C = 12.7 mm (1/2 inch) outer diameter (OD) copper conductor
• D = 25.4 mm (1 inch) square aluminium tube, with wall tickness of 2 mm For ¼ wave power divider, the impedance theoritical needs to be around 35, 35 ohms and impedance of the equation = 35.88 ohms with test result SWR Reading <1.3

Notes :

• If you construct it with circle tube, the equation Z = 1.38 x log (1.00 x (D/d)).
• (D/d) ratios for ¼ and ½ wave length with more ports ( 1-4, 1-6 , and 1-8) at next update
• Ring Circular FM Broadcast Antenna to support your power combiner with more than one antenna at the next update
