For this module, you will investigate the operation of antennas. Antennas can both transmit and receive electromagnetic waves. You see antennas everywhere from portable radios and cell phones to radio transmission and cell network towers. In this laboratory, you will look at two types of antennas, a Linear Antenna and a Linear Antenna. Experiment with the simulation by changing the wavelength control and observe the changes in results.
- Linear Antenna shows the magnetic field near a half-wave linear antenna fed from one end. You can vary the length of the antenna using the "Length" slider.
- Linear Antenna shows the magnetic field near a full-wave linear antenna fed from the center. You can vary the length of the antenna using the "Length" slider and you can vary the separation between the two halves of the antenna using the "Feed Separation" slider.
