Abstract (en)
A microwave antenna (20) comprises a stripline microwave element including an outer conductor (36) having a radiating face (22) and an oppositely disposed backing face (30), an inner linear conductor (28) lying parallel to the radiating face within the outer conductor (36), and a dielectric between the outer conductor (36) and the linear conductor (28). There is a pair of slots (24, 26) in the radiating face of the outer conductor (22), the pair of slots (24, 26) being oriented at 90 degrees to each other and being of unequal length. The inner linear conductor (28) is oriented such that it is not parallel to either of the slots (24, 26). A dielectric (33) resides between the outer conductor (36) and the inner linear conductor (28). <IMAGE>
