This research pioneers a ground-breaking system meticulously engineered to swiftly detect vehicular accidents and dispatch immediate alerts to both emergency services and pre-assigned contacts. This ...symphony of cutting-edge technologies includes an accelerometer sensor attuned to detect acceleration in any vector, a dynamic Liquid-Crystal Display (LCD) display for rapid alert dissemination, an assertive buzzer for resonant alarms, a Global System for Mobile (GSM) module for the swift transmission of distress messages, and pinpoint location data provided by a Global Positioning System (GPS) module. A user-friendly 'cancel' button acts as an escape hatch from potential false alarms. Orchestrated by the dexterity of an Arduino Uno microcontroller, this ensemble orchestrates a harmonious ballet of safety. This solution boasts cost-effectiveness, steadfastness, and unparalleled efficiency. Rigorous testing across diverse scenarios confirms its precision and robustness. By enhancing accident detection accuracy, expediting emergency responses, and facilitating rapid location dissemination, this innovation serves as a vital lifeline, empowering both passengers and rescue services upon accident initiation. With location data as its guiding star, emergency services gain a swift navigational edge, offering a beacon of hope in the battle against accident-related casualties.
This paper proposed a radial line slot array antenna (RSLA) design integrated with circular ring resonator for 5G millimeter-wave applications. It is intended to converge the Federal Communications ...Commission (FCC) standards that specify the millimeter-wave operating bands from (24-40) GHz. It intends to create a wideband compacted RLSA antenna. The benefit of this design technique is the high achievable gain, which is desirable for mm-wave bands due to their short wavelength. The proposed RLSA antenna with metamaterial of is designed for 28GHz resonance frequency and uses Rogers 5880 substrate material with a thickness of 1.57 mm. The air gap cavity between the copper plate and the substrate is g/2 which is equivalent to 2mm. The RLSA antenna with CRR metamaterial reflector operates between (25-38) GHz and it achieved peak realized gain of 20 dBi. This work is reducing the designed antenna size and making it suitable small device for 5G mm-wave band.

This work presents a two-element multiple-input multiple-output (MIMO) antenna for IoT applications. A single antenna element is designed with wideband characteristics covering 4.2 to 7.5 GHz and is ...arranged in a perpendicular configuration to realize MIMO structure. The proposed design configuration exhibits good isolation without using decoupler with 47% fractional bandwidth and gain up to 5.1 dB. The presented structure has acceptable values for Envelope Correlation Coefficient (ECC), Diversity Gain (DG) and good isolation less than -26 dB. Being a low-cost solution, proposed design is suitable candidate for IoT application operating in 4-7.8 GHz, in particular, for 5-6 GHz, 4.70-6.19 GHz and 5.5-5.7 GHz operating bands.
