Frequency-Independent Antennas
IRE International Convention Record, 2014 Broadband communication systems require antennas that can cover a very broad range of frequencies, in some cases with a bandwidth ratio of 40:1. Such a broadband radiation performance cannot be achieved with any of the designs studied in the previous chapters. In this chapter we will study a class of antennas known as frequency-independent antennas.
