ABSTRACT: The
C-band is allocated for commercial telecommunications via satellites. Amateur
satellite operations in the frequency range 5.830 to 5.850 GHz for down-links
and 5.650 to 5.670 GHz for up-links are allowed by International Telecommunication Union. The X-band is used for
terrestrial broadband communication, radar applications, and portions of the
X-band are assigned for deep space telecommunications. In this paper, a design
of 4 × 1 Ultra Wide Band (UWB) antenna array for C-band and X-band applications
is introduced. Metamaterial sixteen-unit cells are incorporated into each
antenna element for radiation characteristics enhancement purposes.
Permeability and permittivity of metamaterial unit cells are
obtained all over the operating bandwidth. UWB unequal power divider is used to
feed the proposed four elements antenna array based on Chebyshev excitation
method. The proposed antenna has a suitable 3 dB beam width and gains all
over the operating bandwidth which extends from 5.6 GHz to 10.9 GHz. The
proposed antenna covers 60% and 72.5% of the
C-band and X-band, respectively. The proposed antenna is fabricated, measured,
and good agreement is obtained between simulated and measured results. The
obtained performance ensures the suitability of the proposed antenna array for
C-band and X-band applications.
