“…Orthogonal frequency division multiplexing (OFDM) is one of the most representative multicarrier modulation (MCM) techniques due to its capability to e ciently cope with frequency selective channels for 5G broadband wireless communication [1]. However, OFDM is restricted by some obstacles such as the high peak-to-averagepower ratio (PAPR) [2], which drives the OFDM signals to work in the nonlinear region of high-power amplifiers (HPA) [3] and this leads to appearing undesirable degradation in the Bit Error Rate (BER) performance [4]. An increase in back-o↵ of HPA will lead to a loss in power e ciency, therefore, PAPR reduction is necessary and more e cient for energy optimization.…”

Partial transmit sequence (PTS) technique is a fairly suitable scheme to mitigate the high peak-to-average power ratio (PAPR) problem inherent in 5G multicarrier system-especially considering high-order QAM modulation design. However, the high computational complexity level and the speed of the convergence for optimizing the phases of the transmitting signal restricts this technique in practical applications. In this paper, a low-complexity frequency domain evaluated PTS (F-PTS) based on spacing multi-objective (SMO) processing algorithm is proposed to reduce the PAPR values. The PAPR performance are accurately predicted in terms of modifying relative dispersion in the frequency domain. As a result, the complexity of searching the optimal phase factors and IFFT computing is simplified. Moreover, frequency domain and time domain evaluating PTS (FTD-PTS) is employed to search the optimal solution within reasonable complexity. Simulation results verify that the F-PTS scheme can obtain well secondary peaks with lower computational complexity, and the FTD-PTS scheme effectively reduces PAPR with a faster convergence speed.

“…It allows future researchers to improve their designs, making them smaller in size, exhibiting multiband behavior and better performance for the devices. The unique metamaterial properties of the SRR and CSRR have been implemented in the microwave design such as in antenna, filter, absorber, lens and coupler for size miniaturization [22], multiband behavior [23] and producing excellent performances [24]. The SRR and CSRR are small electrical resonators that originate from the coupling between the inner and the outer ring to create the first resonant frequency.…”

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.

“…The multiband operation is exhibited in [16] using fractal antenna using Koch iteration, however antenna size is considerably bigger i.e., 33.5 × 23.5 mm 2 . Recently, in [17], using split ring resonator (SRR) a single narrowband at 1.1 GHz and ultra wide band (UWB) operation ranging from 2.3 to 6.1 GHz have been reported with an large antenna size of about 34 × 44 mm 2 . A ∕4 rectangular stub loaded with metamaterial for 2.45, 3.5 and 5.8 GHz frequency bands has been designed in [18].…”

A compact triple band antenna with stacked T-shaped strips inside a rectangular ring monopole has been proposed. This novel structure with a slot in the defected ground achieves triple band opration i.e. 2.47–2.77 GHz, 3.3–3.7 GHz and 5.10–6.62 GHz. These bands find application in important wireless communication standards like WiMAX (3.3–3.8 GHz, and 5.25–5.85 GHz, WLAN (2.4 G-2.5 GHz, 5.1–5.3 GHz, and 5.72–5.85 GHz). The antenna is printed on a FR-4 substrate with an overall dimension of $$33 \times 17 \times 1.6 \;{\text{mm}}^{3}$$ 33 × 17 × 1.6 mm 3 . An impedance bandwidth of 11% (2.47–2.77 GHz), 11% (3.3–3.7 GHz) and 25% (5.10–6.62 GHz) is obtained. A good conjunction between the simulated and measured results is inferred from the antenna design analysis.
