Modeling and Design of a Compact Metal Mountable Dual-band UHF RFID Tag Antenna with Open Bent Stub Feed for Transport and Logistics Fields

Advances in Science, Technology and Engineering Systems Journal, Volume 6, Issue 1, Page # 1065–1071, 2021; DOI: 10.25046/aj0601118
Abstract:

In this paper, we have modeled and designed a metal mountable tag antenna that is applied to cover two major UHF RFID bands, i.e., European (EU) (865-867 MHz) and U.S. bands (902-928 MHz). It is applied for many applications, especially in the transport and logistics fields. The tag antenna configuration utilizes microstrip configuration with open…

In Body Antenna for Monitoring and Controlling Pacemaker

Advances in Science, Technology and Engineering Systems Journal, Volume 5, Issue 2, Page # 74–79, 2020; DOI: 10.25046/aj050209
Abstract:

This paper is an extension of work originally presented in 2019 International Conference on Automation, Computational and Technology Management (ICACTM). A micro-strip patch in-body designed antenna is constructed on pacemaker to monitor and control the pacemaker wirelessly. The antenna is intended for ISM (Industrial, Scientific, and Medical) band (2.4 GHz to 2.48 GHz). A perfect…

Design and Analysis of Frequency Reconfigurable Antenna Embedding Varactor Diodes

Advances in Science, Technology and Engineering Systems Journal, Volume 4, Issue 6, Page # 371–376, 2019; DOI: 10.25046/aj040647
Abstract:

In this paper, we present a broadband frequency tunable antenna embedding varactor diodes. The reference antenna structure is a square antenna of patch dimensions [39,2 × 39,2] mm², operating at a single resonance frequency 2.45GHz. The recommended procedure to achieve the frequency shifting is to etch rectangular slots on the patch and to embed two…

Microstrip Patch Antenna for Ultra-Wideband Applications

Advances in Science, Technology and Engineering Systems Journal, Volume 4, Issue 3, Page # 10–15, 2019; DOI: 10.25046/aj040302
Abstract:

A new microstrip patch antenna for ultra-wideband applications is presented in this paper. The design and performance of the antenna component are discussed. The propounded antenna is mounted on a compact FR-4 substrate having dimensions 20 x 30 x 1.6 mm3 with relative permittivity εr=4.3. The rectangular patch antenna is slotted with two types; rectangular…

Design and Simulation of an RF-MEMS Switch and analysis of its Electromagnetic aspect in realtion to stress

Advances in Science, Technology and Engineering Systems Journal, Volume 3, Issue 1, Page # 76–81, 2018; DOI: 10.25046/aj030109
Abstract:

Microelectromechanical Systems (MEMS) are devices made up of several electrical and mechanical components. They consist of mechanical functions (sensing, thermal, inertial) and electrical functions (switching, decision making) on a single chip made by microfabrication methods. These chips exhibit combined properties of the two functions. The size of system has characteristic dimensions less than 1mm but…
