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.

Enthalpy

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 '3-terminal device external modeling'

Very basic question. Consider a 3-terminal device with terminals say A,B,C. Kirchhoff Current Law (KCL) and Kirchhoff Voltage Law (KVL) establish two relationships between the 3 currents entering the terminals and the 3 terminal's voltage pairs respectively. So we have 2 equations in 6 unknowns. To proceed further we need two more (independent) equations in order to solve the circuit the 3-terminal device is connected to (basically one treats such a device as an unbalanced two-port...

Thread 'Question about the voltage between two charged capacitors'

suppose you have two capacitors with a 0.1 Farad value and 12 VDC rating. label these as A and B. label the terminals of each as 1 and 2. you also have a voltmeter with a 40 volt linear range for DC. you also have a 9 volt DC power supply fed by mains. you charge each capacitor to 9 volts with terminal 1 being - (negative) and terminal 2 being + (positive). you connect the voltmeter to terminal A2 and to terminal B1. does it read any voltage? can - of one capacitor discharge + of the...
