I'm in a beam control project and i want to make a phase shifter to use in 2.4Ghz so i would like to know if anyone could tell me any circuit that could help me?
this is the most obvious way of creating a phase shift at such high frequencies.
A quarter-wavelength will create a 90degree phase shift.
A quarter wavelength at 2.4Ghz is about 31mm, cut a piece of coax for the required phase shift and dont forget to allow for the velocity factor of the coax.
yes i want to adjust the phase, because i want to control the radiation pattern! and for that i have to analyse/build an atenuattor and phase shifter!!
i will build an planar antenna array, and also build the necessary circuits to control de radiation pattern. It will be an array with 64 antennas 8x8. So i will have to build attenuators, phase shifters and power combiners because i have to make the adaption and also the control of the beam to made an radiation pattern controled.
