slot spiral antenna to explain its broad-band characteristics. The total electrical e–ciency and peak realized gain of this slot were compared with those of a rectangular slot which is the current slot shape used in SWASS. The gain patterns from an optimised spiral shape slot were simulated and conflrmed by measurement. 2.

Design and practice. This chapter describes practical design and examples of small antennas. The chapter is composed of four sections, which deal with four types of small antenna: ESA (Electrically Small Antennas), FSA (Functionally Small Antennas), PCSA (Physically Constrained Small Antennas), and PSA (Physically Small Antennas).
