A dielectric antipodal flared notch radiator (50) with separate transmit and receive ports (72,76) for phased array and active array antennas. A circulator (80) is integrated directly to the broadside coupled-strip transmission line portions (78,88) of the antipodal flared notch radiator without the use of baluns. The look-in impedance of the radiator element is improved as a result of the circulator and lack of a balun. By sandwiching the antipodal flared notch between two additional layers of dielectric (54,56), the device can be made a building block for broadband active array antennas. <IMAGE> |
