Summary: This article presents a wireless human motion detection system using a stretchable patch antenna with fractal design to resist interference from untargeted deformations. The patch antenna incorporates a Hilbert fractal pattern to achieve mechanical stretchability of about 40% and a maximum gain of 2.95 dB at 2.5 GHz. The study also explores the influence of fractal order on the mechanical stretchability and radiation properties of the antenna. The resonant frequency of the stretchable fractal antenna exhibits high sensitivity to different deformations, remaining largely unchanged with bending and showing a linear dependence on tensile strain. Experimental verification of remote detection of joint motions is achieved using a wireless on-body strain sensor based on the fractal design-based stretchable microstrip antenna.

Summary: This paper studies different mesh configurations of stacked meshed patch antennas and investigates the effect of conventional slot loading on stacked meshed patches. The results show that the stacked mesh design performs comparably to a continuous metal stacked design in terms of resonant frequency, return loss, gain, and radiation efficiency. The antenna, implemented using Low Temperature Co-fired Ceramic (LTCC) technology, is intended for space application.

Summary: Silenite-cobaltite nanocomposites with chemical formula (Bi13Co11)Co2O40-Co3O4 were synthesized and characterized for use as a substrate in a microstrip patch antenna. The sample was prepared using the combustion method with urea as fuel, and structural, vibrational, and morphological characterizations were conducted. The nanocomposite showed stable real relative permittivity and low losses, making it suitable for X-band communication services. The microstrip patch antenna design using the nanocomposite as substrate achieved good agreement with simulations, with only 0.39% error in resonance frequency, and exhibited coherent results for a directive device in terms of radiation pattern.
