It is possible to use a parallel plate capacitor as an antenna to pick up the electric component of an electromagnetic signal ? Thanks .
Using a Capacitor Antenna for Electromagnetic Signal Pickup
Click For Summary
SUMMARY
Using a parallel plate capacitor as an antenna to pick up electromagnetic signals is generally ineffective due to the shielding effect of the armatures on the electric field. However, variations of dipole antennas, such as those utilizing capacitive "top hats" or end plates, can enhance signal reception. These designs are akin to center-loaded dipoles or monopoles, which incorporate inductance to create an electrically longer appearance. This approach allows for improved electromagnetic signal pickup.
