    Antenna Bending
AI Thread Summary
Bending antennas is crucial because parallel wires radiate energy inefficiently due to their opposing currents, which cancel each other out. The fields produced by parallel wires decay rapidly with distance, limiting their effectiveness. In contrast, a V-shaped antenna, with nearly-parallel wires at a small angle, enhances radiation by allowing for constructive interference. This design improves the antenna's ability to transmit and receive signals over greater distances. Understanding these principles is essential for optimizing antenna performance in communication systems.

why does the bending of antenna is important?why we can't just use two parallel wire to radiate energy?
thanks.

The fields decay too quickly with distance if the wires are parallel.
 
In parallel wires, the curernt would flow in opposite directions, cancelling their radiation effect.

The V antenna has nearly-parallel wires, but they are not parallel, and the small angle makes the radiation.
 

Thread 'Underwater piezoelectric sensor array receive sensitivity'

Hi all I have some confusion about piezoelectrical sensors combination. If i have three acoustic piezoelectrical sensors (with same receive sensitivity in dB ref V/1uPa) placed at specific distance, these sensors receive acoustic signal from a sound source placed at far field distance (Plane Wave) and from broadside. I receive output of these sensors through individual preamplifiers, add them through hardware like summer circuit adder or in software after digitization and in this way got an...

Thread 'What happens if shielded cable has short to the shield?'

While I was rolling out a shielded cable, a though came to my mind - what happens to the current flow in the cable if there came a short between the wire and the shield in both ends of the cable? For simplicity, lets assume a 1-wire copper wire wrapped in an aluminum shield. The wire and the shield has the same cross section area. There are insulating material between them, and in both ends there is a short between them. My first thought, the total resistance of the cable would be reduced...

Thread 'Question about bonding ground and neutral'

I am not an electrical engineering student, but a lowly apprentice electrician. I learn both on the job and also take classes for my apprenticeship. I recently wired my first transformer and I understand that the neutral and ground are bonded together in the transformer or in the service. What I don't understand is, if the neutral is a current carrying conductor, which is then bonded to the ground conductor, why does current only flow back to its source and not on the ground path...
