COMPACT WIDEBAND CPW ANTENNA FOR C AND X BAND APPLICATIONS
Abstract
Planar Microstrip Patch Antennas are well-known for
their light weight, tiny size, and ease of construction. A
microstrip patch antenna (20mm X 20mm X 1.6mm) with
a permittivity of 4.4 and a loss tangent of 0.02 was built
utilizing a FR-4 Glass Epoxy substrate. As a radiating
element, a semicircular patch with a diameter of 11.84mm
and a microstrip feed line with a width of 3.8mm was
created. The simulation was carried out using the HFSS
tool, which employs the Finite Element Method. In the
frequency range from 6.06 GHz to 12.24 GHz, a reflection
coefficient of less than -10dB was found, encompassing a
bandwidth of 6.18 GHz. In the specified frequency range,
a maximum gain of 7.86 dBi was obtained. For the
suggested CPW-based microstrip, an ideal radiation
pattern with Omni direction in E-Plane and Isotropic in HPlane
was obtained.
