Abstract. Design of
the seven
element microstrip antenna array for operation in L1-band is presented
in this
article. Numerical calculations were made by the use of the
finite difference
time domain method. Advices on the application of the manual mesh
settings are given. Differences between
simulated
characteristics of
the radiation field and
the reflection
coefficient of a
single isolated antenna
element and
an element in
the array
are
noted. The construction of manufactured antenna
system is described. A comparison
between simulated and measured S-parameters is
also presented.
