- Abstract
Methods for tuning resonance frequencies of elements of frequency-selective surfaces with the help of varactors are considered. The varactors are placed both in breaks of the conductor inside elements and in gaps between elements. Results of the approximate calculation and measurement of resonance frequencies of elements of frequency-selective surfaces of various shapes (butterfly, loop, and snake) with different-type varactors are presented. The measurement is based on the waveguide method. It is shown that, when varactors are placed in an element, the maximum relative resonance frequency change (37%) is reached with an element having a large self-capacitance (butterfly shape) and a small-capacitance varactor (MA46H120). The efficiency of the method for extending the resonance frequency tuning range of the element by means of the inductive shunting of the varactor circuit is estimated.
