“…The BPF design using resonators coupled through sections of transmission lines having quarter‐wave length has been widely studied in literature. This type of filter was first presented for waveguide applications but, more recently, it was also proved in microstrip technology or in tunable frequency selective surfaces . A general representation of a tunable quarter‐wavelength coupled filter is given in Figure A.…”

This work presents the first example of monolithically integrated phase shifter based on a pass‐band filter architecture. The proposed configuration was realized mapping a classical quarter‐wave coupled filter circuit into its lumped element equivalent. Phase control is achieved by controlling the pass‐band through tunable tanks employing varactor diodes. A demonstrator was prototyped in the 24 GHz ISM band using a 0.25μm SiGe BiCMOS technology. Experimental results show 180° of phase range and maximum transmission losses of 8 dB. The main feature of this configuration is that it allows controlling the transmission losses by design and that its size is extremely compact.

“…Second, the bandwidth, B, determines the slope of the phase response and, in turn, its usability for controlling the phase of the transmitted signal. Assuming a linear phase response within the pass‐band, the slope, s, can be written as

normals = - \frac{Nπ}{2 normalB}

“…Other common tuning mechanisms include limited direct mechanical tuning (via MEMS devices), and the use of chemically, thermally, or static electric field-controlled liquid crystal-based devices [10][11][12][13] for optical and infrared wavelengths as well as RF and mm-wave applications [5], [14], [15]. All of the electronically-controlled systems require bias signals for each unit cell to be either integrated into the resonant unit cell geometry such as in the case of a slot-based structure [16], or designed to minimally impact the desired electromagnetic response. There has been some interest in optically-controlled radio-frequency antennas where an optical fiber couples a signal from an external laser diode to a photosensitive component [17], and such a scheme could be extended to metamaterials in the future, although such a design would be infeasible with current technology.…”

Spatial tuning of a volumetric metamaterial introduces many new design considerations that strongly affect the performance and practicality of a resulting system implementation. This paper discusses the design rules and procedures for spatially reconfigurable metamaterial systems using a tunable near-zero-index slab with adjustable shape as a representative design example. We propose a split-ring resonator-based metamaterial where each resonator is tuned in and out of resonance using a varactor diode to change the effective material response. The periodic, hexagonal tiles may be combined and connected in a planar spiral to form a cylindrical metamaterial panel whose radius may be arbitrarily large. Multiple panels are then stacked, with appropriate cropping, to form a volumetric metamaterial slab.

“…It is widely used in fields such as satellite communication [2], antenna beam-steering [3], electromagnetic shielding [4], meta-materials integration [5] and radar cross section (RCS) reduction [6][7][8] based on its spatial filter characteristics of electromagnetic (EM) waves such as bandpass or bandstop response. However, performance requirements for FSSs are different according to application environments.…”

Abstract-An annular-ring element for building a miniaturized bandstop frequency selective surface (FSS) structure which possesses a superior performance with respect to electromagnetic wave polarizations and incident angles is introduced in this paper. The proposed element has prominent miniaturization characteristics with a unit dimension of 0.061λ × 0.061λ, where λ represents the freespace wavelength corresponding to resonant frequency. Miniaturization of the proposed FSS element is achieved by constructing special meandered strips in geometry and arranging lumped components between the elements. The advantage of this method lies in its great simplicity in tuning the resonant frequency of FSS by adjusting values of the printed capacitors rather than rebuilding the geometry. The obtained FSS also exhibits a stable performance in terms of angle stability and polarization insensitivity. Prototypes of the proposed FSS are fabricated and measured to verify design method. Measurements are well in line with simulation results.
