Despite decades of searching for this signal, astronomers have yet to find it. The problem is that our Earth is too noisy, ...

Additionally, the series resonance phenomenon is shown to be mainly due to the resonance of a single characteristic mode. Analysis of a simple wire dipole antenna, an edge-fed patch antenna, and a ...

The course covers antennas and radiowave propagation in the frequency range above about 100 MHz. The antenna part covers basic theory, wire, dipole, apertures/horn, reflector, and microstrip, and ...

[Peter]’s solution is a simple antenna made from a 31-mm length of silver wire. One end of the wire is formed into a loop by wrapping it around a 5-mm drill bit and bending it perpendicular to ...

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 module can cover 100 meters if used effectively and it can also cover 1000 meters if you use it with an antenna. This nRF24L01 module is ... SCREEN_HEIGHT, &Wire, -1); struct SensorData { float ...

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 ...

Assembly requires common maker tools such as a soldering iron, solder wire, pliers, a multimeter, safety goggles and gloves. Components attach securely inside an acrylic frame using double-sided tape ...
