Abstract: This article provides information on the study carried out on patch antennas in order to solve the problem of setting up a multitude of antennas on a shared site, this causing telecommunications operator to have high costs for the acquisition of equipment as well as their maintenance. the results obtained prove with certainty that it is possible to substantially reduce the number of antennas on a co-shared site by combining each time two or more frequency resources in an antenna.
