Microwave Variable Delay Line Using a Membrane Impregnated with Liquid Crystal
Summary :
A microwave variable delay line using a membrane impregnated with liquid crystal was newly fabricated. By employing the membrane impregnated with liquid crystal to the liquid crystal layer of the delay line, the phase-shift response becomes fast independently of the liquid crystal thickness. Experimental results show that the phase-shift response time of 33 ms, which is two orders of magnitude faster than that of a conventional one, is obtained. The new delay line also exhibits a 270-degree phase-shift and non-dispersive delay characteristics over a wide microwave-frequency range, although a higher control voltage is needed. It is also clarified that the phase-shift characteristics to the control voltage depend on the pore size of the membrane. This membrane impregnated with liquid crystal also enables us to make the variable delay line thin and flexible.
