Abstract :
A successful design for a broadband compound printed air-fed array antenna is presented. By using the tapered sized frequency selective surface (FSS) on the cover and the inversely tapered sized artificial magnetic conductor (AMC) on the base as well as removing the four corners of the cover and base for the weak aperture field there, a common (VSWRles 2.0:1 & -1 dB gain-drop) bandwidth of 9.84% centered at 10 GHz and a common bandwidth of 7.9% centered at 10.5 GHz are obtained respectively in simulation and measurement. The differences between the simulated and measured results are also analyzed.
