Before we can design an antenna or discuss antenna types, we must understand the basics of antennas, which are the fundamental parameters that characterize an antenna. So let us learn something. We'll start with frequency and step through radiation patterns, directivity and gain, and ultimately close with an explanation on why antennas radiate.

This is a senior undergraduate or first-year graduate level textbook on antenna fundamentals, design, performance analysis, and measurements.
28 lip 2021 · Antenna design is very theoretical, but it’s largely based on empirical work and lots of experimentation. If the antenna is simple like dipole, ground plane, or loop, it may work out for you.
AN91445 explains antenna design in simple terms and provides guidelines for RF component selection, matching network design, and layout design. This application note also recommends two Cypress-tested PCB antennas that can be implemented
An intuitive tutorial of antennas and antenna theory. This website is designed to present a comprehensive overview of antennas, from design, to measurement and theory. Unnecessarily complicated math is avoided throughout.
The handbook will widely cover not only all key antenna design issues but also fundamentals, issues related to antennas (transmission, propagation, feeding structure, materials, fabrication, measurement, system, and unique design challenges in specific applications).
How is antenna design done? It starts with a firm understanding of all the requirements. Then if you have a pretty good idea about many of the fundamnetal antenna types, you can begin to figure out which might work for the application. Antenna design can range from virutally impossible to very simple. It is all about the situation and constraints.
