Abstract—This paper presents the design of a dual stacked microstrip
antenna over the frequency range of 9.5–16 GHz. Investigations show
that in the new structure the impedance bandwidth of the antenna
is increased to 44% and the thickness of the antenna decreases to
0.14λ. Furthermore, the gain bandwidth of the antenna (above 8 dB)
is increased to 5.1 GHz (40%).
