Narrative:

ILS downwind 5000 ft; 210 KTS. While on approach; our radio communications were intermittent at best. We continued on a 20 mile downwind leg that we had been told to expect; then used TCAS to sequence ourselves with other traffic and continue the approach. We declared an emergency and continued to broadcast in the blind. Near zzzzz intersection we heard that we were cleared for the approach and then landing. On the ground we lost communications again prior to entering the ramp. Despite some troubleshooting; we were unable to determine the cause of our radio problems.
