Hal’s-Wave Dipole Antenna

What is a half-wave dipole antenna?

• an antenna constructed using a conductive tube or metallic element that has a length equal to the electrical half wavelength.

• a metallic structure that captures and/or transmits radio electromagnetic waves.

• one that is short when compared to a wavelength at the operating frequency.

A half wave dipole antenna is mostly used in radio receivers at around what hertz does it operates ?

• 3KHZ-600KHZ

• 3KHZ-300GHZ

• 6-KHZ-300GHZ

Which of the following is a characteristic of half dipole antenna?

• The voltage and the current level vary along with the wavelength

• when the voltage and current meet they create a destructive wave

• The voltage and current level vary along the length of the radiating section of the antenna.

When the charges are induced in the positive half cycle of the dipole, the electrons

• Move towards the charge

• Move away from the charge

• Move to the center

When the negative charges are induced in the dipole the electrons tend to

• Move towards the dipole

• away from the dipole

• Move towards the charge
