In the recent years the number of works on the analysis of properties of resonant microstrip radiators in the array antennas (AA) has increased. If using such radiators the service frequency band width (SFB) is generally limited up to 35% at voltage standing wave ratio =1,5 [1].
This work shows that the use of microstrip radiators with small electrical sizes placed over the impedance surface in the AAs is one of the possibilities to provide simultaneously a wide SFB and scanning angle domain up to ±60° within the principal planes…
