In
this study, a new microstrip patch geometry, called Seljuk star, is proposed.
The performance of the designed antenna
is compared with the performances of square and circular microstrip antennas,
which are two other popular patch geometries in
literature. The design procedure consists of two phases: First, the patch
dimensions of circular and square antennas are
taken as the same with Seljuk star dimension. Then the patch surface areas of
antennas are fixed to the area of Seljuk star patch and patch dimensions are
calculated for the new designs. The effect of different patch types on
bandwidth are investigated. Rogers Duroid 6010 (h= 3.175 mm, ɛr=10.2)
is chosen as the substrate of the antennas which are expected to have a
bandwidth center at 5800 MHz. All antenna designs are simulated in HFSS. Each
individual antenna is intended to be working at a single frequency, but during
the simulations multiple resonance are obtained in many designs. Therefore, the
bandwidth and frequency comparisons are done for each resonant frequency among
themselves. In comparison to the circular patch geometry with the same surface
area, bandwidth is improved 10.57 times, as a result. The deviation between the
theoretical calculations and simulations is % 1.38, which is the smallest
deviation among all results. Based on this, it is
observed that Seljuk star microstrip patch antenna has a better performance when
its dimension or surface area is chosen as same with circular or square
antennas. The proposed Seljuk star patch shape is believed to have a high
potential to be used in future research.
