Post Switches for Phased Array system

Hi all.

I am planning to make a phased array system inspired by G. L. Charvat Sir's work. Described below is my planned setup.

Radar Front End : Original Coffee Can Radar Minicircuits components
Antennas : Patch Antenna (Will be custom made)

My question is regarding the RF Switch.The one used by Charvat Sir, is expensive and unavailable in my country. I want to fabricate a switch module from a commercially available SP4T MMIC switch on a microstrip PCB. The problem is the one I have available is a Reflective switch instead of a Absorptive one originally used. Will it be a issue? Please note I am use low gain patch antennas.

Thanks in advance.
