Abstract:In today's modern living, there is enormous emphasis on commercial
electronic products to not only perform, but look good as well. In
an electronic system, often the most cumbersome and difficult device
to deal with is the antenna. So that it performs as designed, the
antenna sometimes evolves into a relatively large structure making
it vulnerable to damage by the elements or other external
influences. In some cases it is often perceived as being ``ugly''
in the eyes of the consumer particularly if it protrudes from the
device. The future vehicle is a typical example where many antennas
will be used for the number of multimedia services that are destined
for it. Another example is antennas being placed on the surface of
soldier's helmets to be worn out in the field for new military
communications systems. Wideband antennas are needed in both these
situations, but often their planar shape positioned on the metal
spherical surface of the vehicle roof or the composite spherical
surface of the helmet present visual as well as technical problems.
Shaping an antenna to have the same surface as the object it is
attached to is an obvious solution. However, the properties of a
planar microstrip antenna change and are more difficult to model and
manufacture when its shape resembles that of a sphere.
Understanding these changes and the manufacturing methods used to
produce these antennas for these applications is the focus of this
research.
