Infinite phased arrays of microstrip antennas with parasitic elements. Application to bandwidth enhancement

Description

Microstrip phased array antennas obtained by the association of two interdigitated biperiodic coplanar subarrays are presented. One of these two subarrays is fed, and the other is parasitic. This type of array is studied for rectangular or triangular patches, using an infinite phased array model for the theoretical approach. The frequency bandwidth obtained with this geometry is larger than that of conventional monolayer microstrip antennas.< >
