Hello,
I am trying to measure the time-varying electric field of a parallel plate capacitor using short dipole antenna, but my numbers are off by almost 100 times. I have a parallel plate capacitor, A=23cmx11cm, d=10cm. I apply 10sin(2pi*1KHz) and 10sin((2pi*1KHz)+180deg) to each plate. I am using a L=2cm dipole. So based on the book, peak electric field is E=(10+10)/d=200V/m. Now measured electric field using dipole is E=V/L=40mv/2cm=2V/m. I need help to understand the reason?!
Thanks
