Electric Dipole Propagation Pattern [Dipole Antenna] 📡

Here, 3D propagation pattern of an electric dipole (antenna) is being shown. In addition to the radiation pattern, we also project the transversal and vertical planes of the propagation pattern and actually show how the waves would be propagating in different planes. Basically, along the

How does an Antenna work? | ICT #4

Antennas are widely used in the field of telecommunications and we have already seen many applications for them in this video series. Antennas receive an electromagnetic wave and convert it to an electric signal, or receive an electric signal and radiate it as an electromagnetic wave. In t

Doppler Effect Animation

We demonstrate the Doppler Effect where a traveling transmitter excites spherical waves in fixed time intervals. While a frequency increase in the direction of travel is observed, a reduction of frequency occurs in the opposite direction.

Tune an Antenna Using a NanoVNA

In this video we show how to tune an antenna’s standing wave ratio (SWR) using a NanoVNA. This is an economical alternative to a full antenna analyzer and can be used to ensure the antenna is resonant at a desired frequency. Topics and timestamps: 0:00 – Introduction 2:56 – Unboxing the

Horn Antenna Simulation using Finite Difference Time Domain (FDTD) Method 📡

Here we show the radiation from various horn antenna types using the finite difference time domain algorithm. First we starts with a basic horn antenna and compare it with free space propagation. Then, horn antenna is compared to a waveguide without any horns. Finally the impact of horn an

Radio Wave Properties: Electric and Magnetic Dipole Antennae

An HP model 3200B VHF Oscillator and ENI model 5100-L NMR RF Broadband Power Amplifier provide a 300 MHz signal to a half-wave dipole antenna. The voltage variation along the length of the dipole transmitting antenna is made evident by touching one end of a 8-Watt fluorescent lamp. A coppe

Our dynamic universe is ablaze with cosmic fireworks. Stars explode and send out beacons of light that are a million to a billion times brighter than our sun. Fireworks generated in these explosions are what synthesize most of the elements in our periodic table: while some explosions, call
