Hi,iam doing a project on rectangular patch antenna array(4 elements)
operating freqeuncy=2.4ghz
substrate is FR4 dielectic constant =4.4
height=1.5mm
lamda=60mm
distance between each patch=lamda/2=30mm
T-junction power divider is being used.
simulation is done in hfss
for 2 array,gain=5.5db and directivity=9db at 2.4ghz

Reflector? The patch antenna does have some back side metalization anyway, so that's more or less the reflector. Maybe the back side metalization is too small.
