In this paper, the resonance and radiation characteristics of patch antennas
fabricated with two different types of dielectric substrates have been investigated
and compared at GSM 1800 MHz band. At first, the above-stated characteristics
of a patch antenna loaded with conventional plastic substrate have
been investigated. Later a high permittivity dielectric material (barium titanate)
has been used as the antenna substrate. The main goal here is to reduce
the antenna size with a high permittivity dielectric material and then to compare
its resonance and radiation performance with the earlier low permittivity
substrate loaded prototype. It is found that with the use of high permittivity
substrate the antenna volume gets smaller (about 6% of the plastic substrate
prototype) although the gain decreases by around 2.5 dB.
