Detailed explanation-1: -Micro waves are unidirectional. When an antenna transmits microwaves, they can be narrowly focused. This means that the sending and receiving antennas need to be aligned. The unidirectional property has an obvious advantage.

Detailed explanation-2: -Microwaves, as with all electromagnetic radiation, travel in all directions indiscriminately, usually going back and forth along a waveguide with equal ease.

Detailed explanation-3: -Microwaves, infrared, visual light, ultraviolet and x-rays are all not unidirectional in nature. Far away from the source they look unidirectional, very close they look omnidirectional.

Detailed explanation-4: -The range of electromagnetic spectrum between 10 kHz and 1 GHz is known as radiofrequency (RF). Radio waves are omnidirectional. When an antenna sends radio waves, they are propagated in all directions. This defines that the sending and receiving antennas do not have to be aligned.
