In this paper, influence of Circularly Split
Ring Resonators with its accompanying circular
microstrip patch antenna are investigated.
Proposing a 5850 to 7075 MHz band of working
frequency, by means of microwave laminate RT/D
5880 (εr = 2.2 and thickness of 1.82 mm). The
antenna is wholly organized into three layers
consisting of circular copper sheet as ground
plane, an undersized main radiator for where
signal will pass through to resonate and ended
with designed split rings entrenched on layer
three laminate. All layers are separated by an air
gap, simulated and optimized carefully using
Microwave Studio of Computer Simulation
Technology Suite (CST). Provided that, dimension
of air gap, split ring quantity and entrenched split
ring width are monitored as key controllers. Via
transient solver, it presents corresponding Sparameter
results and provides 3D view farfield.
Thus demonstrating how each key controllers
influence the antenna in terms of bandwidth,
directivity, gain and efficiency produced. These
works conclude that adaptation of split rings can
enhance and improve this particular antenna.
