“…In order to validate our prediction both theoretically and experimentally, a monopole antenna is designed on E4D paper to cover a very wide frequency range including two WLAN bands (2400‐2483.5 MHz and 5150‐5850 MHz). The dielectric permittivity and loss tangent of this substrate were characterized in our previous work where we obtained ε r = 3.184 ± 0.2%, tan δ = 0.092 ± 0.26%. For the design, the thinnest sheet of paper (104 μm thickness) is chosen for higher flexibility of the antenna.…”

In this article, the authors conduct a study of bending effects of a paper‐based printed antenna in order to predict the behavior of an antenna placed inside a package with restricted dimensions. The study begins with a model of an electrical dipole consisting of two misaligned parts to evaluate qualitatively the effect of the angle between two parts and the proportion of their lengths on the radiation properties of the dipole. In order to validate the theoretical prediction, a wide‐band “mushroom‐shaped with two arms” monopole antenna structure printed on 0.104 mm thick paper is proposed. This antenna covers a very wide frequency range from 1.8 GHz to over 10 GHz, including two WLAN bands. Its radiation patterns are nearly omni‐directional at 2.45 and 5.5 GHz. The study of substrate bending effects shows that the matching properties of the antenna are maintained, but the antenna radiation patterns are rotated by an angle with respect to the case without bending. The results of our study can be used to predict the performance of an antenna when it is deformed in a telecommunication set‐top box with restricted dimensions.

“…The dielectric characterization of paper has already been carried out by many researchers for microwave frequencies and the relative permittivity is found to be in a consistent range between 2.5 and 4. Various methods for characterization of paper such as use of T resonator [16], cavity perturbation method [27][28], ring resonator method [18,29] and transmission line method [30][31] are reported in the literature. In the present report, paper substrate is characterized using two methods, namely cavity resonator and transmission line method.…”

In this paper, a super ultrawide band planar inverted F antenna (PIFA) has been proposed for wearable applications on a low cost, ecofriendly paper-based substrate. This work is a first and important step towards the progression of conformal flexible antennas for a body area network. The proposed antenna has measured impedance bandwidth of 10.6 GHz, which covers almost all the bands of a wireless body area network i.e. GSM (880-960 MHz), GPS (1565-1585 MHz), DCS (1710-1880 MHz), PCS (1850-1990 MHz), UMTS (1920-2170 MHz), ISM (2.4-2.4835 GHz), WiMAX (3.3-3.8 GHz), HIPERLAN (5.15-5.35 GHz), WLAN (5.725-5.850 GHz) and UWB (3.1-10.6 GHz). Initially, the electrical characteristics of paper are extracted using Cavity Resonator and Transmission line method and then used for the design and fabrication of the proposed antenna. The measured results are in good agreement with the simulated results. This paper also focuses on analysis of the effect of electromagnetic absorption in terms of specific absorption rate for a human arm with frequency exposure at 0.9 GHz, 1.5 GHz, 1.8 GHz, 3.5 GHz, 2.45 GHz, 5.2 GHz and 5.8 GHz and is found to be within the recommended limit by FCC.

“…Based on used printing technology, the edges or surfaces of printed structures can be uneven, and their mechanical resistivity is usually lower [1]. PE technologies are revolutionary for research and development activities as well as for production efficiency, thus many studies are focused on the usability of PE in the highfrequency domain [7][8][9]. Previous studies show the usability of printed transmission interconnects [10] up to ones of GHz with a low attenuation constant [11].…”

Printed Electronics (PE) technology has obtained considerable attention due to the simplification of the manufacturing process that can be fully additive. In addition, PE offers possibility to use low-cost, low-temperature substrates, such as polyethylene terephthalate (PET) foil, which could serve as an alternative to conventional high-frequency substrates, like Rogers. In this study, digital printing technology direct write, or so-called dispensing is used to print microstrip Rectangular-shaped resonators (RSRs) on a flexible PET foil and a semi-flexible Rogers 4003 substrate. Resonators are printed by a contact dispenser Nordson EFD Pro Plus 4L/A from a conductive silver-based DuPont PE 874 paste. The selected straight and bent RSRs have deep resonance frequencies at 2.50, and 1.90 GHz, with an amplitude of about −50 and −60 dB, respectively. The mentioned resonators are simulated and printed; then the results are compared with a good match. Resonators on Rogers shows a good match between simulation and realization. On a PET substrate, a 6% shift of transmission zero location is observed. To better understand some probable challenges during the manufacturing of high-frequency resonators, the structure of printed layers is characterized, and the manufacturing process itself is completely analyzed.
