| Abstract: | The
paper presents the design and development of an X-band linearly polarized
microstrip array antenna. The array elements are fed by corporate feed network,
which improves the impedance bandwidth of the two element rectangular
microstrip array antenna (2RMSAA) by 15.38%. By increasing the array elements
from two to four and eight, multiband operation can be achieved with improved
impedance bandwidth. These multiband array antennas may provide an alternative
to large bandwidth planar antennas in applications where large bandwidth is
needed for operating at two separate transmit-receiver frequencies. When the
two operating frequencies are far apart, a multiband antenna can be used to
avoid the use of separate antennas. Experimental results for the array antennas
in term of return loss, radiation pattern, -3dB beam width, and gain are
presented |
