Antenna array having apparatus for producing time-delayed microwave signals using selectable time delay stages |
摘要 |
A scanned antenna array includes time delay stages each having at least one time delay sub-circuit. Each time delay sub-circuit includes a sub-circuit input, a sub-circuit output, a first delay line, and a second delay line. A first diode switch connects a first end of a selected one of the first and second delay lines to the sub-circuit input. A second diode switch connects a second end of the selected one of the first and second delay lines to the sub-circuit output. The sub-circuit output is connected to one of another time delay sub-circuit or to an output of the time delay stage. A respective transmit/receive (TR) module is coupled to an output of each time delay stage and issues a TR module output signal. A plurality of antenna elements radiate an output signal received from the corresponding TR module.
