Summary: | In this paper, a compact miniaturized EBG loaded
with surface mounting capacitor has been developed. The
dimension of the EBG patch with approximately λ/36 has been
achieved with dimension highly dependent on the capacitor
values. The integration of the capacitive loaded miniaturized
EBG with a couple of microstrip patch antenna has reduced
approximately 12dB mutual coupling within the elements at the
antenna resonance frequency of 2.2GHz. The antenna E-plane
gain has been improved for more than 2dB with 3dB reduction in
side lobes when comparing the traditional array with the array
integrated with EBG. The propagation characteristics and gain
of the array have been analyzed using CST Microwave Studio
(CST MWS). The measured results have shown good agreement
with the simulated results. The miniaturized EBG will be very
useful in minimizing the space within the array antenna
especially for the MIMO application. |
