“…In this work, grapheme material is used as conducting element on polimyde substrate and author proved that antenna is Suitable for THz application. Microstrip patch antenna using alumina ceramic substrate was proposed by Kazuhiro Kitatani 4 . Alumina substrate has high dielectric constant (ε r ), and the size of the antenna is reduced to a more compact form.…”

Modern wireless applications necessitate compact handheld devices capable of operating at wide range of frequencies with minimum power. A suitable choice and size of the antenna play a role in reducing the power consumption of the transceivers. Microstrip antenna is usually preferred for such transceivers operating at microwave frequencies because of low profile and easy installation. In this paper, a design of microstrip patch antenna using copper nano material fabricated with sputtering process is proposed and analyzed by its performance. The thickness of the microstrip antenna is reduced by 50 times compared to the antenna fabricated using conventional etching process. The performance of the antenna is evaluated using the metrics of Return Loss, VSWR, and Radiation Pattern. The proposed antenna achieves a return loss of −20 dB at 2.4GHz. Further, the return loss is less than −10 dB for the frequencies ranging from 5 to 17 GHz. The maximum gain of 10 dB is achieved at 15.5 GHz.

“…Because of its suitable permittivity (ε r ≈ 10) and low microwave loss, alumina is the most widely used material for microwave packaging, substrates and antennas. 5 However, because of its fragility, difficulty in processing and high cost, alumina is mainly used in high-end applications in industries such as the military, aerospace and automotive industries. Ceramic-polymer composites having 0-3 connectivity could achieve high performance by combining the superior electric properties of the ceramic and the mechanical tenacity, chemical stability and processability of the polymer.…”

Unique polymer-ceramic composites for microwave antenna applications were prepared via melt extrusion using high-density polyethylene (HDPE) as the matrix and low-density polyethylene (LDPE) coated BaO–Nd2O3–TiO2 (BNT) ceramic-powders as the filler. By incorporating LDPE into the composites via a coating route, high ceramic-powder volume content (up to 50 vol%) could be achieved. The composites exhibited good microwave dielectric and thermomechanical behaviors. As BNT ceramic content increased from 10 vol% to 50 vol%, the permittivity of the composites increased from 3.45 (9 GHz) to 11.87 (7 GHz), while the dielectric loss remained lower than 0.0016. Microstrip antennas for applications in global positioning systems (GPS) were designed and fabricated from the composites containing 50 vol% BNT ceramics. The results indicate that the composites that have suitable permittivity and low dielectric loss are promising candidates for applications in miniaturized microwave devices, such as antennas.

The frame of the paper is the integration ofPZT actuators and sensors within thermoplas tic mechanical structures. The objective of the work reported here was to select the appropriate thermoplastic materials for the smart thermoplastic manufacturing. In order to reach this objective, a comparative study was realized between different thermoplastic materials taking into consideration the PZT patch maximum temperature, the overheat time o f the PZT patch during injection process, and the PZT loss in piezoelectric properties due to its thermal fragility.
