Triple Band

In this paper, triple-band planar monopole Microstrip Antenna intended for different applications like Bluetooth, Wi-Fi, Wireless LAN (2.4 GHz), LTE 2500 band, WiMax (3.5 GHz), and a piece of C-band applications. The reception apparatus has been intended to work at different recurrence groups, for example, 2.25 – 2.5 GHz, 3.32 – 3.97 GHz, and 5.90 – 8.67 GHz individually. The proposed receiving antenna comprises of a planar monopole reception apparatus imprinted on RT/duroid 5880 substrate (through a general permittivity of 2.2 and loss tangent of 0.0009) and the base side printed with a truncated ground. The planar monopole reception apparatus has been viably structured and reproduced by utilizing Ansys-HFSS design tool. The component of the proposed receiving antenna is 40 × 28.4 × 1.575 mm3 . The reenacted outcome shows return loss, voltage standing wave ratio (VSWR), radiation pattern, and gain of the Antenna. Also, the truncated ground plane structure is straightforward, vigorous and possesses little space, building it appropriate for different applications.

Novel Concept

This paper presents the design and development of an X-band microstrip gap-coupled sectoral patch array antenna for application in wireless systems. A novel concept of bandwidth enhancement is considered for gap-coupled sectoral microstrip patch array antenna, which uses one active receiving antenna and multiple parasitic elements with finite ground plane. The parasitic elements give the possibility of creating a directive antenna beam. A broadband of 1 GHz with a return loss of −50 dB has been achieved in X-band along with a directivity of 11.1 dBi and reduced side lobe level to −23.7 for 3 dB angular width.

The article presents the results of studies to improve the National primary standard machine for hardness of metals on the shore D scale GET 161-2001, which were performed in FSUE “VNIIFTRI” from 2016 to 2018 in accordance with the technical task of Rosstandart.The improvement was carried out in order to ensure the uniformity of hardness measurements on the Leeb scales. The created new parts of the primary standard machine, which are settings for reproducing hardness numbers on the Leeb scales, are considered. Metrological characteristics of the upgraded and adopted National primary standard machine (GET 161-2019) were investigated, the budget of measurement uncertainty was calculated for reproducing hardness numbers on the Leeb scales.

Abstract Ply steer is a rolling contact phenomenon which manifests itself as a lateral force acting at the ground plane of a tire constrained in yaw or a change in slip angle of a tire free to yaw. It has long been known that radial tires generally exhibit greater ply steer than do bias tires. However, the only previously published quantitative analysis of this phenomenon considered the multi-layer cord-rubber composite by means of netting analysis, which is not very accurate at cord angles typical of radial tire belts. A simple, explicit expression is developed herein by combining modern composite laminate theory with two very simple, uniform-stress-state tire-road contact models. The ply-steer results predicted by the resulting expressions are compared with some experimental results and the agreement is found to be reasonably satisfactory.
