Your Guide on How Microwave Antennas Work


Microwave antennas are among the main modern communication networks. They are designed to receive and transmit electromagnetic radiations with a wavelength between infrared emissions and radio waves. The radiations can go through space or atmosphere. They enable the use of wireless devices and track weather patterns. Even though most people believe that essential things are usually sophisticated, microwave antennas are often simple.
Transmission and Reception
An antenna is a long metal wire connected to radio to aid in sending and receiving signals. The signals are in the form of microwaves, a type of electromagnetic wave.
The microwaves are transmitted very quickly through the air and are used to carry information. The transmitter changes the necessary information into a specific wave and then broadcasts it via air. The wave will finally get to another antenna which further transforms it into an electrical signal that can be processed by various other parts of the radio. The radio transforms it into information that a human can discern.
There are few ways in which an antenna can receive or transmit a signal. The easiest one is via a line of sight system where wave goes straight to the receiver and has a limited range. Besides, it’s vulnerable to blockage by physical objects, the main reason why communication firms don’t use it but instead go for the vast network of antennas or other options. The other option is Ground waves which are suitable for short and average distances. These waves follow the curves of the planet, which helps them go beyond the horizon. The transmitters can even transmit their waves upwards and then bounce them off the atmosphere to ensure that they send them over long distances and that they maneuver obstacles. The mechanism operates best during night time, the reason as to why it’s easiest to pick up distance radio stations late at night.
Large Networks
All the above methods have a limited range and are also vulnerable to blockage by physical obstructions. The signals that finally go through may also encounter the issue of low quality if they go for a long distance or over areas with adverse conditions. The solution towards such matters is to create a system of connections of antennas that can transmit signals to others. These antennas operate like any other since they encode data in the form of a wave, send it, receive it, and finally decode it. However, some antennas will resend the data as a new wave to ensure that it can reach its destination.
Splitting the process into a cluster of few steps prevents problems and signal degradation. Despite that it increases the cost of infrastructure, communications are so critical such that the increased cost equals the improved clarity and credibility.
