Wireless antenna is an electrical device which converts electric currents into radio waves, and vice versa.

Which of the following antenna used in wireless base stations and provides a 360 degree horizontal radiation pattern?

Omnidirectional antenna

Parabolic grid antenna

Yagi antenna

Dipole antenna

Answer: Dipole antenna

Explanation: Dipole antennas are those antenna which have the omnidirectional feature of the radiation pattern that is, it can receive the signal from every direction. They are the used for the radiation of the RF signals (radio frequency) on horizontal plane in 360 degrees.

These antenna can be utilized for the working in wireless base station because they can resonate at almost half of the wavelength as compared with the frequency.
