It begins with the fundamental limitations of bandwidth and matching, and then provides detailed discussions on the design of loaded dipoles, ferrite loops, patches and unusual substrates and dielectric resonator antennas.
An interesting section on fractal antennas is also provided. I actually thought fractal antennas had an improved performance, but it turns out the better antennas are the simplest antennas. As previous stated, the author discusses several examples of antennas that are based on good physics but are poor performers I think fractals fall into this category as well as design examples of antennas that are based on both poor physics and poor performance.
Chapter 2, which is the second largest chapter in the book, discusses superdirective antennas. Small dipoles and loops are superdirective; their directivity remain 1.ssllabel-admin.wecan-group.com/del-usuario-propietario-ford-la-fusin-que.php
Electrically Small, Superdirective, and Superconducting Antennas
Excessive array superdirectivity most arrays are made up of small dipoles or loops inflict major problems in the efficiency of antennas low radiation resistance and narrow bandwidth. Superdirective antennas have limitations in their capabilities of bandwidth, efficiency and tolerances. Request permission to reuse content from this site.
