Conclusion

The content of this article is not exhaustive, and there are other antenna technologies such as miniature antennas, broadband and ultra-broadband antennas, and metamaterial antennas, which will be the subject of specific articles. Following on from [E 3 280] , it offers a progressive presentation of antenna technologies, increasing the size of the antenna and, consequently, its gain and directivity. It distinguishes between small antennas with gain around a few decibels, planar sources from 5 to 10 dB, horns from 10 to 25 dB and large antennas above 25 dB. With this classification, you can quickly choose a family...
