What is the importance of antenna?
The purpose of an antenna is to transform RF signals into electromagnetic waves, propagating into free space in the transmit mode, and in the receive mode, to transform electromagnetic waves back into RF signals. Antennas are reciprocal and have, therefore, the same performance in a receive and transmit mode.
What is the significance of antenna design in the field of communication?
An antenna plays a vital role in a communication system. It is used in both the transmission and reception of radio frequency signals. In fact, an antenna is a structure that is capable of radiating electromagnetic waves or receiving them, as the case may be.
What are the antenna requirements?
Antennas are required by any radio receiver or transmitter to couple its electrical connection to the electromagnetic field. Radio waves are electromagnetic waves which carry signals through the air (or through space) at the speed of light with almost no transmission loss.
What do you need to know about antenna design?
Define Your Antenna Requirements. Based on your four design constraints from step 1, you can quickly define your antenna requirements – the type, size, etc. that you’ll need to order or design. The next post in this series will explain how to do that.
What kind of antenna do you need for Nordic board?
If your design doesn’t have as much space, you might need to choose a smaller chip antenna or even a custom design. The bent monopole antenna on the Nordic board has an omnidirectional antenna pattern, whereas a design that requires a directional antenna might place the antenna directly over a ground plane.
What kind of antenna do I need for Bluetooth?
By the end of this post, you’ll know the factors in your design that determine whether you need a directional antenna. Bluetooth only uses one frequency band – the 2.4GHz ISM Band (2.4-2.4835 GHz).
Do you need ground clearance for PCB trace antenna?
This reference design happens to have enough space for a PCB trace antenna – here, it’s a bent monopole, which requires ground plane clearance (note the lack of ground plane around the antenna). If your design doesn’t have as much space, you might need to choose a smaller chip antenna or even a custom design.
