Analog phase shifter for compensating the distance between 8 antennas at 3.5Ghz

Hi folks.

I have a question for you.
I'm making a device with 8 antennas in a circle and need a analog phase shifter so we can shift the signal and compansate for the distance between the antennas.
I'm working on 3.5 Ghz.

I found this, but it's only for 5-18 GHz.

Does anybody have any experience with this?

i have some experience at VHF & UHF phase shifters. may be my advice works.

1) find out distance to port from source in MM
2) convert it to number of wave length at your frequency
3) findout the wave length in the medium you design the 50 ohm line from source to port in MM
4) convert your phase shift needed to wave length in MM
5) add to number in (3)
6) design pcb traces for those MM length
