Directional and Distance Considerations
Two decent ways to divide radiating devices, or antennas as they are commonly called, is based on how the energy exits the device and enters space. Omnidirectional antennas transmit in numerous directions, while directional antenna’s transmit beams or thin cones in one main direction.
If a microwave’s 1,000 watt output, for example, were fed into an omnidirectional antenna, the energy would scatter away from the device into many directions. Not much would get cooked this way, as microwaves normally contain the energy inside a box, repeatedly frying the insides in a repeating cycle of reused energy. An omnidirectional antenna wouldn’t have such a high efficiency of energy use, with only objects near the omnidirectional microwave experiencing electron disturbances which might cause heating and cooking.
