Meet the Challenge of Designing Electrically Small Antennas

Meet the Challenge of Designing Electrically Small Antennas

Antenna sizes for many communications applications are mainly driven by customer requirements, and are generally much smaller than simple quarter-wavelength monopoles. Due to fundamental limitations, however, antennas can only be made so small without sacrificing tradeoffs in performance. Similarly, very compact antennas with ground planes too close to the radiating element suffer from certain performance issues.1 The tangential components of alternating current (AC) flowing on the antenna’s radiating surface tend to be nullified by the induced surface current on the ground plane.
