Planar Microstrip Array Antenna with Rectangular Configuration Fed with Chebyshev Power Distribution for C-Band Satellite Application

A C-band satellite receiving antenna requires high gain and narrow beamwidth at around 4 GHz frequency.
Microstrip antennas, which have a low profile characteristic,
have remained promising for various wireless applications.
This paper proposes a rectangular patch antenna design that
arranged by planar arrays and Chebyshev feeding technique to
achieve high gain and low sidelobe levels for C-band
applications. The antenna design is simulated and
parameterized by using CST Microwave Studio. The results
show an increase of gain and decrease in the side lobe level
obtained from the model using the Chebyshev technique
compared to the uniform power divider technique. With the
proposed feeding of the 4x4 array antenna, it achieves gain and
sidelobe level of 16 dB and -28.5 dB, respectively. The 8x8
array antenna with the Chebyshev technique reaches gain
performance, and sidelobe level of 20.2 dB and -24.3 dB,
respectively. Meanwhile, the 16x16 microstrip array antenna
can achieve gain and sidelobe level of 24 dB and -23.8 dB.
These results indicate that the proposed array design can
contribute to design an antenna suitable for C-band
applications
