In this video, I'm making a DIY Yagi Antenna specifically designed for use with 868MHz LoRa to try and beat my previous distance record of 20 km. The antenna is built with 3D printed boom that already ...

The basic principle of radar systems is simple enough: send a radio signal out, and measure the time it takes for a reflection to return. Given the abundant sources of RF signals – television ...

Traditional radio-based systems often suffer severe attenuation underground, as soil and rock absorb or scatter electromagnetic waves. By contrast, magnetic induction uses low-frequency magnetic ...

Abstract: In this letter, a machine-learning-assisted graphic antenna design method using dynamic acquisition ensemble (ML-GDAE) is proposed. First, a dynamic normalized Gaussian network-based antenna ...

Abstract: This paper investigates the radiation characteristics of a quasiisotropic small planar antenna using CMA (characteristic mode analysis). In recent years, sensor devices have been used in ...
