A novel approach to decode information in a chipless RFID tag using signal space representation (SSR) is presented. SSR represents 2^b possible tag signatures of a b-bit tag as linear combinations of a small set of orthonormal basis functions. Each signature encoding a binary bit sequence is represented by a point in an $L$-dimensional constellation. Prototype 3-bit chipless RFID tags are used to...
A multi-band antenna which can be used as a passive strain measurement device is presented. The dimensions of the antenna will change when different strains are applied, resulting in changes in the resonant frequencies. The proposed antenna resonates at multiple frequencies. By creating slots on the patch of the antenna, these resonant frequencies shift to a higher or a lower value for different strain...
Recently, electric power steering systems (EPS) are developed to compensate the transmitted steering forces according to the applied torque. To measure the torque via wireless sensing, the purpose of this study is to investigate a measurement system with two SAW sensors via wireless RF signals. In this implementation, the SAW sensors are attached on a rotational axis and micro chip 8051 is used to...
This paper presents a novel H-Shaped reconfigurable microstrip patch antenna fed by a Grounded Coplanar Waveguide (GCPW) for wireless applications. The uniqueness in the presented antenna design relies in the ability to select the number of operating frequencies electronically by using a varactor diode. The antenna structure consists of coplanar waveguide (CPW) input with an H-shape printed on a PCB...
A novel miniature antenna for a wireless pressure measurement system based on a passive surface-acoustic-wave (SAW) sensor is presented in this paper. The SAW sensor used for this application works at 434 MHz in the Industrial-Scientific-Medical (ISM) band. The miniature antenna (lambda/12 times lambda/17 times lambda/63) [6 times 4 times 1.2 cm3] consists of a planar inverted F antenna with a spiral...
Microstrip Antennas (MSAs) consist of a metallic radiating patch on one side of thin dielectric substrate and other side is ground plane. Most important advantages of MSAs are low profile, light weight and compatibility with integrated circuit technology. MSAs are used in mobile communication, satellite communication, radar, direct broadcasting, global positioning systems and remote sensing. The major...
In this paper, the design of a compact planar bandpass filter above a defected ground plane is presented. The filter is designed as a combination of microstrip resonators and exploits the properties of a planar electromagnetic bandgap (EBG) structure patterned unto the ground plane of the printed circuit board material to provide a very wide stopband of up to 5 times the fundamental frequency. The...
