A microstrip antenna (10) has two dielectric layers (12, 14) bonded together with an array of conducting strips (20, 22, 24, 26) interposed therebetween, the strips (20, 22, 24, 26) being spaced to define a slot (30, 32, 34) between each pair of adjacent strips. A conductive ground plane (16) is disposed on a first outer side (12a) of the two bonded dielectric layers (12, 14), and an array of radiating patches (40, 42, 44) are disposed on a second outer side (14a) of the two bonded dielectric layers (12, 14), each of which patches is positioned over a corresponding slot, the array of patches being spaced apart to form an aperture (52, 54) between each pair of adjacent patches (40, 42, 44). Responsive to electromagnetic energy, a high-order standing wave is induced in the antenna and directed beam is transmitted from and/or received into the antenna. |
