Abstract

A concept of frequency-reconfigurable artificial magnetic conductor (AMC) based on open-stub-loaded varactors with wide tuning range is presented. The design consists of a square patch with two open-stub-loaded varactors connected to two edges of the patch along one direction. The working principle is based on the impedance transformation characteristics of the stubs, which is exploited to load varactors for attaining the frequency reconfigurability. By applying a variable bias voltage on the varactors, the AMC operation frequency can be tuned continuously from 3.36 to 4.98 GHz while maintaining a reflection amplitude better than -3 dB. To satisfy the miniaturization requirement of the design, a commercially available substrate material WavePro from Garlock Sealing Technologies with a high relative permittivity of 10 is used in this design. The AMC performance is analyzed and characterized based on reflection coefficient and phase tuning range of its unit cell in simulation.
