Abstract:
A novel and subtle design of a circularly polarized
microstrip line feed elliptical slot monopole antenna with an
intention to use in C-Band (4-8 GHz) is proposed in this
communication. Due to notable as well as remarkable
performances, this small and compact antenna with ample
applications in the arena of wireless communication upholds its
strong position among the previous work of similar types. For
designing and simulating the proposed antenna for exploration
of its feasibility to use in the C-band wireless applications
especially satellite-based communication system, CST MW
studio is used. Different categories of calculations and
performance studies have been performed while maintaining a
suitable environment of free space for wireless communication.
The antenna with overall dimension of 50 mm × 30 mm × 0.836
mm, where the substrate is used is Teflon and Copper is used as
radiating patch as well as ground plane, is placed for evaluating
its performance in respect of return loss, radiation and total
efficiency, VSWR, gain, directivity, direction of surface current,
axial ratio (AR) bandwidth, and reduction of cross polarization
(XP). An impressive return loss (-41.7 dB) at the resonance
frequency and suppression of XP of 33.50 dB have been
accomplished with other marvelous results.
