—A novel single element KSA (Kingdom of Saudi
Arabia) sign shape, and two element array (Ultra Wide Band)
KSA sign shape slot microstrip antennas are presented. A
novel KSA sign shape EBG cells are applied to reduce the
mutual coupling between array elements with the same shape.
The results show that a reduction in mutual coupling of 8 dB is
achieved at first band (2.1 - 2.99) GHz and 33 dB at second
band (5 – 9.43) GHz. The microstrip array was studied by CST
simulator and fabricated by proto laser machine with precision
25μm. The antenna can be used in the military or RFID
