Resumo Inglês:

In this experimental study a novel design has been
developed to improve the antenna parameters in terms of
impedance bandwidth and radiation properties. A 4-element
rectangular array antenna (refereed as antenna 1) operating in the
range of 10 to 16 GHz with multi bands is used as a reference
antenna. The impedance bandwidth and other radiation properties
have been enhanced by using defected microstrip structure (DMS)
and defected ground structure (DGS). This study is further
extended to 8-element array. The design consideration and
experimental results of the proposed antennas are presented and
discussed.
