Design and Study of Twin Band Quad Terminal Reflector Loaded Wearable Radiator With Reduced SAR and High Gain
Dheeraj Nagar, Prashant Ranjan, Atanu Chowdhury
International Journal of Communication Systems, 2026
This research presents a wearable radiator with dual‐band and quad‐terminal that is compact and made on polyimide substrate. Dual metallic rings integrated with the feed line create the band notch in between 2.66 and 3.28 GHz and convert the wideband into dual band feature. By taking use of spatial and polarization diversity, the separation level among various terminals is more than 25 dB. A single‐negative (SNG) metamaterial‐based metasurface (MS) reflector‐cum‐absorber surface located just below the radiator reduces the specific absorption rate (SAR) for the 1‐ and 10‐g tissue models by more than 90%, while also increasing the radiator gain to 5.65 and 4.55 dBi. ANSYS HFSS 2023 R2 was used for full‐wave simulations, and a Keysight E5071C VNA in both flat and bending configurations was used for experimental validation. Using a three‐layer human tissue phantom (skin, fat, and muscle) with 1‐ and 10‐g averages, SAR assessment was conducted in accordance with IEEE/IEC 62209‐1 and ICNIRP recommendations. Its performance in two frequency bands, 2.3–2.65 and 3.3–3.65 GHz, is confirmed by measurement findings. All these features make the radiator applicable for WBAN application.
Energy efficient cascade connected Peltier sensor based air conditioner using liquid coolant heat exchanging methodology and internet of things
Chiradeep Ghosh, Atanu Chowdhury, Himadri Mandal, Himadri Sekhar Dutta
Instrumentation Science and Technology, 2026
This paper presents an energy-efficient air conditioning system integrating cascaded Peltier TEC1-12715 thermoelectric sensors and Internet of Things (IoT) technology. The prototype employs a liquid coolant heat exchanging methodology using ethanol which enhances thermal conductivity and minimizes environmental impact. An ESP32 microcontroller, paired with the Blynk platform, facilitates real-time temperature monitoring and remote control for smart operation. The system maintains a consistent indoor temperature of 21 °C in a 49 square feet room, achieving this setpoint in 24 min under constant power conditions, regardless of external temperature variations. Operating with a maximum power consumption of 570 watts per hour, the unit provides heating and cooling functionalities while delivering an energy savings of up to 0.45 units compared to a 0.75–ton conventional system. Comparative analysis with traditional air conditioning highlights its improved efficiency, suitability for small-scale smart home applications. This innovative approach demonstrates the potential of combining thermoelectric cooling with IoT and alternative coolants for sustainable climate control solutions.
Automatic Actuation-Based Life-Saving Methodology Inside Smart Ambulance Using Fuzzy Control and IoT
Chiradeep Ghosh, Atanu Chowdhury, Himadri Mandal, Himadri Sekhar Dutta, Niladri Sekhar Datta
IETE Journal of Research, 2026
The Internet of Things (IoT) is frequently integrated with remote health monitoring inside smart Ambulance systems. It has been noted that medicinal response time inside a smart ambulance is a crucial factor. The consultation delay between the paramedics and the doctor may be a serious issue for the severe patient, which may lead to a life-threatening situation. Hence, faster (the golden period) impose of emergency drugs results in a higher expectancy of survival. In this context, an economical remote health control system is incorporated where a life-saving drug dispensing system has been attained automatically inside smart ambulances under medical emergency during hospital transit. ESP32 with a Fuzzy Takagi–Sugeno (T-S) based multi-sensor network has been introduced to monitor the patient’s vital parameters to draw the medical attention and to auto-dispense the right amount of emergency lifesaver drugs through the intravenous saline to the patient’s body by controlling medical actuators within 10 ms. The system’s performance is measured and validated on the test bed scenario with sensor accuracy of 98.5%, getting tested with 70 patients.

This paper presents a circular patch antenna having two “<tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$\mathbf{Z}$</tex>” slots and a defected ground structure (DGS) suitable for mid-band 5 G applications (sub- 6 GHz band). A semi-spherical layer of the Polyfion Cuflon layer <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$(\epsilon \mathbf{r}=2.1)$</tex> is attached to the ground to enhance the gain resulting in an improvement in radiation efficiency. The proposed antenna dimension is 40 mm <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$\times 40 ~\text{mm} \times 1.6 ~\text{mm}$</tex> based upon a FR-4 substrate (<tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$\epsilon \mathbf{r}=4.4$</tex>). The proposed antenna covers a bandwidth of 2 GHz to 6.5 GHz. Without the attached layer, the maximum gain is 3.5 dB while the attachment of the layer increases it up to 6.1 dB. The Radiation efficiency is also improved from 62 % to 81 % by implementing the attachment. The overall structure is designed and simulated in HFSS 21.0 software.
