In this article, a novel, simple, and compact structure of dielectric resonator antenna is proposed, which provides wide bandwidth across proposed mm wave band for microwave image sensing with considerable gain using a lossy FR‐4 epoxy substrate and thick FR4 as DRA. A DR can be excited using four‐line feed using a circular loop type feed network. These line feeds maintain phase difference of 90° to produce CP. This antenna provides approximate constant gain of 8.6 dB on 25‐26 GHz band and 3 dB axial ratio bandwidth is almost 1 GHz from 25.2 to 26.2 GHz, Impedance bandwidth of the proposed antenna is 3 GHz (24‐27 GHz). This antenna can be used in microwave image sensing and wearable sensors applications, due to its compactness (30 × 30 mm2), in mm wave band.

“…A wireless transceiver system is required to send the measured current to a remote reader. The currently existing wireless transceiver systems consist of a battery, an antenna, a voltage regulator, an amplifier, a de-modulator, a multiplexer, an A/D converter, and a digital processor 28 – 30 . These kinds of wireless systems have several issues including signal distortion and addition of noise when passing the wireless electronic circuits, and heavy re-chargeable battery installation to activate the circuits and current sensor.…”

A chipless, wireless current sensor system was developed using a giant magnetoimpedance (GMI) magnetic sensor and one-port surface acoustic wave (SAW) reflective delay line for real-time power monitoring in a current-carrying conductor. The GMI sensor has a high-quality crystalline structure in each layer, which contributes to a high sensitivity and good linearity in a magnetic field of 3–16 Oe. A 400 MHz RF energy generated from the interdigital transducer (IDT)-type reflector on the one-port SAW delay line was used as an activation source for the GMI magnetic sensor. The one-port SAW delay line replaces the presently existing transceiver system, which is composed of thousands of transistors, thus enabling chipless and wireless operation. We confirmed a large variation in the amplitude of the SAW reflection peak with a change in the impedance of the GMI sensor caused by the current flow through the conductor. Good linearity and sensitivity of ~0.691 dB/A were observed for currents in the range 1–12 A. Coupling of Mode (COM) modeling and impedance matching analysis were also performed to predict the device performance in advance and these were compared with the experimental results.

“…Ultrasound techniques are based on the acoustic properties of the tissue and rely on the transmission, diffraction, and reflection of acoustic wave within it. Its sound frequency range is low (1)(2)(3)(4)(5)(6)(7)(8)(9)(10)(11)(12)(13)(14)(15)(16)(17)(18)(19)(20) to ensure deep tissue penetration. 9 The echoes are separated by the time delay of reception and the received signal strength.…”

This article presents the design of a low complexity, low power, small‐sized, wearable, inkjet printed, cheap, and noninvasive radio frequency (RF) based sensor array for pulmonary edema and emphysema condition monitoring inside the patient chest. The RF sensor consists of 38 electrodes and 37 ports. The size of the sensor is 4 cm × 89.4 cm to cover the chest of an average adult. The sensor is optimized to operate at 60 MHz. The scattering coefficients Si1 are measured at each passive port and then the Least Squares (LS) method is used to form an equation for average dielectric constant estimation. The dielectric constant estimation method is used to detect the presence of water/air in human and porcine lungs. The average measured dielectric constants of normal human lung tissue, edema, and emphysema infected lungs are estimated with errors of 3.54%, 4.83%, and 4%, respectively. The porcine lung tissue‐mimicking phantom with proper electrical properties is formed using a water and salt (NaCl) mixture. To detect the different stages of pulmonary edema, 200 mL water balls are inserted in the inner layer of the chest model. The measured errors were 2.68%, 0.87%, 2.18%, and 2.8% for normal porcine lung, adding 6 water balls, adding 12 water balls, and adding 18 water balls, respectively.
