antenna that physically resembles the ear of a bat. The
antenna consists of a circular ground plane with a
central monopole element. An equilateral triangular
conducting plate is curved around the ground so that the
base of the triangle is electrically connected to the
perimeter of the circle and is of the same length. The
input characteristic is reminiscent of a simple monopole
above a circular ground, providing there are a sufficient
number of modes in the triangular plate at the frequency
of interest. In contrast to the plain monopole, certain
frequencies yield a high gain and a radiation pattern
with low side lobes. Measurements presented in this
paper suggest that the antenna performance is broadly
comparable with its acoustic analogue, although there
are differences between the acoustic and
electromagnetic implementation which have yet to be
resolved.
