Which type of antenna is show on the radiation patterns?

• A.Dipole
• B.Yagi
• C.Patch
• D.Omnidirectional

Correct Answer: A

Explanation
A dipole antenna most commonly refers to a half-wavelength (/2) dipole. The physical antenna (not the package that it is in) is constructed of conductive elements whose combined length is about half of a wavelength at its intended frequency of operation. This is a simple antenna that radiates its energy out toward the horizon (perpendicular to the antenna). The patterns shown are those resulting from a perfect dipole formed with two thin wires oriented vertically along the z-axis.
