Abstract :
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.
