“…The outcomes of the present work are on par with the composites listed in Table 2. However, the present work shows higher dielectric constant, lower loss tangent, and lower volume fraction values in comparison with [23]. From the loss tangent perspective, the present work shows a lower loss tangent than [48] and [51].…”

“…The antenna is one of the most crucial constituents of a communication system that directs incoming and outgoing radio waves [22]. The choice of antenna material is essential in antenna design because each material has unique properties, benefits, and drawbacks [23]. In this regard, many elastomer materials, such as natural rubber, silicone rubbers, acrylic elastomers, and polyurethanes, have been described as being suitable for use as flexible polymeric matrices.…”

Here, the eligibility of silicone rubber‐nanoceramic composites as flexible substrates for sub‐6 GHz 5G antennas is investigated. Two different composites are prepared using the solution mixing method, namely mono and hybrid composites. The reflection and transmission coefficient (S‐parameters) of composites are measured using a rectangular waveguide‐based transmission line technique in conjunction with a Vector Network Analyzer (VNA) at C‐band frequencies (4–8 GHz). The Nicolson–Ross–Weir (NRW) algorithm is adopted to extract the complex permittivity and loss tangent of the material under test. Due to the synergetic effect, the silicone rubber hybrid composite (0.12BiVO4+0.12LaNbO4) exhibits the advantage of a lowered loss tangent while retaining a good dielectric constant at 5.78 GHz. A rectangular microstrip patch antenna is designed and simulated with CST software using 0.12BVO/0.12LNO/0.76SR composite as a substrate. Moreover, based on the simulation, the antenna with the proposed substrate has acceptable performance at 5.78 GHz with the return loss, directivity, and gain of −25.05 dB, 5.46 dBi and 2.74 dBi, respectively. As a result, the composite material's ability to act as a suitable substrate for a 5 GHz Wi‐Fi antenna is confirmed.

“…In this work, the polymer of polydimethylsiloxane (PDMS) is integrated with magnetic iron oxide (Fe 3 O 4 ) to form a magneto-dielectric material. PDMS is a silicon-based elastomer with good electrical and mechanical properties such as modified dielectric properties, isotropic and homogenous, flexibility, durability, and transparency [1,2,[26][27][28]. The polymer PDMS, commercially known as Sylgard184 silicone elastomer, consists of two components which are the elastomer base and curing agent.…”

In this paper, a comparison microwave method between Transmission and Reflection using a Coaxial Cable and complimentary double split ring resonator (CDSRR) for characterization of magneto-dielectric material is proposed. This method enables the determination of both relative permittivity and permeability of magneto-dielectric material. The CDSRR resonates at 3.46 GHz with a quality factor of 127 in unloaded condition. To determine the effects of permittivity and permeability on the shift of resonant frequency, the electric and magnetic fields are localized in two separate zones in the CDSRR sensor. Prediction formulas are proposed to extract the value of real permittivity and permeability from S21 parameter. For Transmission/Reflection Method, to extract the dielectric and magnetic properties, Nicolson-Ross-Weir (NRW) are used. The prototypes of proposed sensors are fabricated on a ROGERS 3003 and tested for validation of their functionality. A good agreement between the measured data using Transmission/Reflection Method and CDSRR sensor is observed.
