Towards an Ultra Sensitive Hybrid Mass Sensor Based on Mode Localization without Resonance Tracking
Sensors, 2020 We present a mode localized mass sensor prototype based on a hybrid system excited at a fixed frequency slightly below the resonances. Indeed, we show, both theoretically and experimentally, that this condition yields higher sensitivities and similar ...

Design of Microstrip Dual-Band Bandpass Filter for Sub-6 GHz 5G Mobile Communications.
Jordanian Journal of Computers and Information Technology, 2023 In this paper, a microstrip bandpass filter for dual-band sub-6 GHz 5G mobile communications is designed. The two first resonance frequencies of the stepped-impedance resonator are used as the operating frequencies of the two passbands.

Novel Chipless RFID Technology Using Open Loop Resonator [PDF]
Proceedings of the 2016 International Conference on Electrical, Mechanical and Industrial Engineering, 2016 The paper presents the design and development of a low cost compact chipless RFID system for secure near field data transfer. The proposed system is suitable for use in credit cards, personal data keeping cards and identification cards based on the principle of "data transfer by contact" which at present commonly uses the integrated circuits (IC) or ...

A new microstrip diplexer using open-loop resonators [PDF]
Journal of Microwaves, Optoelectronics and Electromagnetic Applications, 2014 In this paper, a new microstrip diplexer using open loop resonators with compact size and high isolation is designed and fabricated for the WLANs (IEEE 802.11b/g at 2.4 GHz and IEEE 802.11a at 5.2 GHz) applications. The diplexer is formed by two dual-mode band pass filters (BPFs) using an asymmetric fork-form feed line and two open loop resonators. The
