Thin broadband microstrip array antenna having active and parasitic patches

摘要: An array antenna embodying on a dielectric support, periodic succession parallel to an alignment direction of rectangular patches having alternating active and parasitic patches. The are identical, fed with electromagnetic energy in areas such that their sides the radiating sides, sized have same resonant frequency disposed so phase centers at distance apart less than wavelength air associated frequency. separated from by slots constant non-null width extending transversely frequencies near
