“…By incorporating the function of WPT, the duration of the power source in a telecommunication device can therefore be prolonged. Besides WPT, the 6 GHz band is also widely applied in RFID [37] and satellite communications. We would also like to emphasize that, the increasing demand for wireless connectivity has urged the Federal Communications Commission FCC to open the 6 GHz band to ease wireless congestion [38], making it an important band for mobile services as well.…”

We present the design of a tri-band E-shaped printed antenna with C-shaped slots. A Rectangular patch etched with an n-shaped slot is added at the back of the substrate to enhance the bandwidth and the return losses of the resonant bands - particularly, that of the second band. Our antenna is designed to operate at 1.51/2. 46/6.11 GHz. As can be observed from the experimental results, it has 10 dB bandwidths of 157 MHz (1.416 to 1.573 GHz) 358 MHz (2.221 to 2.579 GHz) and 367 MHz (5. 918 – 6. 285 GHz) The first two bands cover the LTE, Bluetooth, IEEE 802.15.4 ZigBee and IEEE 802.11 WLAN applications. The third resonant band covers the unlicensed 6 GHz band which is widely implemented in wireless power transmission, as well as, RFID and satellite communications. In order to ease wireless congestion, the 6 GHz band is also currently being considered by the FCC to be opened up for the use of WiFi applications. Our antenna is fabricated on a single-sided FR4-epoxy, and it constitutes a compact size of 34 mm × 36 mm × 1.6 mm or 0.17λ × 0.18λ times0.0081λ, (based on the 1.51 GHz lowest resonant frequency) The antenna exhibits omnidirectional radiation patterns at the three resonant bands.

Abstract. Here, we propose and investigate designs for devices which use acoustic wave focusators. We have modeled the processes involved by use of the ANSYS software. This was done in order to demonstrate the efficiency of diffractive acoustic elements for mixing particles of different densities and for damping high-frequency vibrations. The proposed designs and technological solutions could be used effectively for mixing reactive substances of various fractions and for damping the effects of high-frequency vibrations on precise measuring instruments.Keywords: focusators of acoustic waves, acoustic diffractive elements, numerical modeling, mixing system, damping system of high-frequency vibrations.Citation: Abulkhanov SR, Goryainov DS. Innovative applications of acoustic waves focusators.
