“…In [1], backward wave propagation with split ring resonators which are loaded along the transmission line is demonstrated. In [2], a bandpass filter is designed using a hightemperature superconducting structure based on SRRs, but the filter was large. In [3] S-shaped complementary resonant structures were used to design a bandpass filter, but insertion loss was high in the passband.…”

In this paper, Compact bandpass filters have been designed. A single bandpass filter was designed using novel triple concentric complementary split-ring resonators placed along the microstrip line in the ground plane. Gaps and via were placed on the microstrip line to control electromagnetic characteristics, resulting in a single bandpass filter. In turn, spiral resonators were attached to the microstrip transmission line at the gaps in the transmission line to obtain a compact dual passband filter. Stepped impedance microstrip line and Tshaped stubs were attached to the microstrip line in between spiral resonators. The structure designed resulted in a Triple bandpass filter. A fractional bandwidth of 3% was achieved at the center frequency of 3GHz. The filter had a 1.5dB insertion loss which is the minimum value in the operating frequency band. The filter resonance frequency was 1.32 GHz and 2.47GHz which have a fractional bandwidth of 7.5% and 4.85% respectively and the corresponding insertion loss was 1.3dB and 1.8dB respectively. The triple bandpass filter had a fractional bandwidth of 1. 16%, 11.4%, and 1.86%, centered at 1.29 GHz, 2.27 GHz, and 3.21GHz with 1.6dB, 1.3dB, and 1.8 dB insertion loss at the respective frequencies. The proposed bandpass filters are useful for GPS, WLAN, WiMAX, and radar applications.

“…A metamaterial is an artificial engineering material that exhibits unusual electromagnetic properties generally not found in nature. The artificial material with changing electromagnetic properties from positive to negative permittivity and permeability provides a potential solution to fulfill demand in designing modern microwave devices such as antenna [18], filter [19], lenses [20] and passive sensor [21]. It allows future researchers to improve their designs, making them smaller in size, exhibiting multiband behavior and better performance for the devices.…”

High Capacity and Miniaturized Flexible Chipless RFID Tag Using Modified Complementary Split Ring Resonator

et al. 2021

This paper aims to produce a high data capacity and miniaturized flexible chipless RFID tag based on the frequency signature using the Modified Complementary Split Ring Resonator (MCSRR). The proposed 19 bits chipless RFID tag using the frequency shifting technique consists of five slotted overlaying MCSRR with Different Width (MCSRR with DW) structures and the dimension of 48 mm × 48 mm. The structure is designed by using a flexible (Polyethylene Terephthalate ) PET substrate with permittivity of 0.2. The operating frequency is between 0.9 GHz and 2.7 GHz. The advancement of slotted overlaying MCSRR with DW structures has successfully miniaturized the chipless RFID tag structure to about 107 mm 2 / bit, 0.02λ 2 mid /bit and 0.09 GHz/bit by maximizing the number of resonators in a limited space and minimizing the frequency separation between the resonators. The omnidirectional tag antenna is incorporated with the proposed MCSRR structure using the retransmission measurement method. The log-periodic antenna with a gain of 5-7 dBi is used for this measurement to improve the range distance between tag and reader system. Based on the retransmission measurement involving the antenna tag, the 19 bits chipless RFID tag which consists of five MCSRR with DW structures can be detected with a maximum range distance of 30 cm and a power transmitted level of 30 dBm.INDEX TERMS Flexible chipless RFID tag, metamaterial, split ring resonator (SRR), retransmission method and size miniaturization.

“…Microwave filters play an important role in a variety of superconducting analog and digital systems and therefore have attracted much attention in recent years. In [1][2][3][4], one very popular topic concerns the design of high-temperature superconducting (HTS) filters based on distributed resonant structures. By replacing normal metal layers with HTS thinfilm materials, these filters provide an extremely low insertion-loss performance that is crucially demanded in modern wireless applications.…”

“…In this work, we propose a new class of LTS lumped element bandpass filter possessing generalized Chebyshev characteristics [22], where the desired frequency selectivity and group delay requirements are achieved with a small number of transmission zeros (TZs). Note that, without cross coupling (compared with literatures [1][2][3][4]), the TZs here are individually generated via resonant couplings (also called frequency-variant couplings), figure 2. As a result, the filter can be structured by a simple in-line topology as figure 3 shows, where the configuration simplicity as well as TZ independence are quite beneficial for RSFQ MPG realization.…”

This paper presents a new class of sharp-selectivity low-temperature superconducting filter that incorporates lumped element resonant couplings. Dependent on a novel synthesis approach, the proposed filter exhibits great advantages such as: (1) a very simple in-line topology (without any cross coupling), (2) extremely compact size based on lumped inductor-capacitor (LC) elements, and (3) multiple transmission zeros (TZs) independently generated and controlled (via each resonant coupling). To facilitate the physical implementation, a group of lumped element circuit models are detailed, where series LC units are adopted for both the resonators and the resonant couplings. Considering an in-line topology here, the entire filter layout is then designed by cascading the lumped models one after another. For verification, a 5th-order bandpass filter centered at 5 GHz, with 500 MHz bandwidth and 3 TZs, is designed, simulated, and tested at cryogenic temperature (4.2 K). Moreover, preliminary simulations of the presented filter in series with an on-chip rapid single-flux-quantum microwave pulse generator are discussed for superconducting quantum applications.
