Patent ID: 8159406

Claim:
A transverse, quadrilateral crossed-dipole radiator for a phased-array antenna, comprising: a first dipole radiator, including: a first monopole radiating element supported by a first outer conductor, a second monopole radiating element supported by a second outer conductor, a first inner conductor, disposed within the first outer conductor and extending therethrough, having an upper termination protruding from the first outer conductor, a first tuned stub, disposed within the second outer conductor and extending partially therethrough, having an upper termination protruding from the second outer conductor, and a first feed strap, disposed above the first outer conductor and the second outer conductor, having one end attached to the upper termination of the first inner conductor and another end attached to the upper termination of the first tuned stub; and a second dipole radiator, arranged orthogonally with respect to the first dipole radiator, including: a third monopole radiating element supported by a third outer conductor, a fourth monopole radiating element supported by a fourth outer conductor, a second inner conductor, disposed within the third outer conductor and extending therethrough, having an upper termination protruding from the third outer conductor, a second tuned stub, disposed within the fourth outer conductor and extending partially therethrough, having an upper termination protruding from the fourth outer conductor, and a second feed strap, disposed above the third outer conductor and the fourth outer conductor, having one end attached to the upper termination of the second inner conductor and another end attached to the upper termination of the second tuned stub, that crosses over the first feed strap.
