This paper investigates the concept of creating
substrates with heterogeneous dielectric properties. By
suitably locating areas of low and high permittivity, the
second resonance can be moved closer to the 1st resonance and
multiband antennas can be created. By combining, the
resonances, the bandwidth of the antenna can be increased.
