There are plenty of small ESP32-C3 IoT boards with a USB-C connector on the market, and while they all look very similar, antenna designs differ, and less thought-out ones may severely impact the WiFi ...

The antennas are dipoles, each fixed to their own PCB by semi-rigid coax cables (“stems”). The signals from the two stems of a dipole are combined into a single signal by a balun. The signal passes ...

Abstract: A novel dual-polarized (DP) magnetoelectric (ME) dipole element, integrated with frequency-selective stepped patches, is introduced. These patches provide an additional lower-band electric ...

This paper demonstrates the analysis of antenna pattern and gain for different designs of full-wave dipole antenna feeding techniques. Seven such techniques were studied and analyzed; symmetrical dual ...

Researchers at UC Berkeley and UC San Francisco are making a huge breakthrough in brain-computer interfaces (BCIs) with their latest brain-to-voice neuroprosthesis. They’re working on restoring speech ...

The Maker’s Pet Robotics Kit is a DIY learning kit designed for robotics enthusiasts, students, and hobbyists who want to explore autonomous navigation and mapping. At its core, the ESP32 works with ...

Abstract: This paper proposes a novel millimeter-wave liquidcrystal (LC)-based reconfigurable folded reflectarray antenna (RFRAA) tailored for Internet of Vehicles (IoV) sensing and communication. It ...
