A novel planar microstrip array antenna is proposed and fabricated. This antenna is composed of one active or fed microstrip patch and two parasitic microstrip patches. Two parasitic patches are coupled with active patch via one-dimensional electromagnetic bandgap (1D-EBG) structures. 1D-EBG structures, maintaining the resonation of active patch, supply microwave power to parasitic patches then no feeding circuits are needed and compact antenna is realized. Because of enhancement of coupling between active and parasitic patches, this antenna performs high gain of 10.8 dBi at 5.8 GHz, comparable to ideal three active patch array.
