Advantages of Microwave frequency | disadvantages of Microwave frequency
This page covers advantages and disadvantages of Microwave frequency. It mentions Microwave frequency advantages or benefits and Microwave frequency disadvantages or drawbacks.
What is Microwave frequency?
The figure-1 depicts Electromagnetic Spectrum with frequency and wavelength. Any frequency above the frequency of 1GHz is in general known as microwave. It usually ranges from 300 MHz to 300 GHz on the scale. Microwave frequencies upto 100 GHz have been used in wide variety of applications.
Following are the silent features of Microwave frequencies.
• Large bandwidth
• Higher Gain
• High Directivity
• Travels in LOS mode
• Less noise in 1 to 10 GHz band

Benefits or advantages of Microwave frequency
Following are the benefits or advantages of Microwave frequency:
➨Microwave frequencies can establish reliable wireless communication which can be used for information transmission. Hence cumbersome wired links can be avoided.
➨It has wider bandwidth and hence it can be used for simultaneous transmission of voice, data, video channels.
➨It has short wavelenth and hence antenna size is smaller and it is light in weight. Hence antennas are installed very easily on any wireless devices including mobile phones, tablets, laptops, aircraft etc.
➨Miniaturized microwave components are available at affordable costs. Moreover microwave towers do not require much area and hence telecom service providers can save in space/land as well as costs.
➨It can generate heat energy which is utilized in many bio-medical applications e.g. skin tightening, cancer treatment etc. Moreover it is used in microwave oven for cooking the food.
Drawbacks or disadvantages of Microwave frequency
Following are the disadvantages of Microwave frequency:
➨As it travels in line of sight, it is affected by obstacles such as mountains, tall buildings etc. This has to be taken care in RF budget planning.
➨The microwave frequencies are attenuated due to various parameters such as rain, snow, fog etc.
➨The microwave frequencies are reflected from flat & metal surfaces.
➨It is diffracted from solid objects.
