Hello,

I am trying to design a patch antenna and I am trying to keep it basic since
antenna and communication theory is not my expertise.  I am working with a
basic rectangular patch antenna with a microstrip feed line.  The
application for this antenna is for the use with a SAW sensor device.  With
using this basic antenna design to get the antenna to a small enough size
(~2cm x ~3cm) the dielectric constant of the substrate the antenna rests on
is ~85.  I was wondering if anyone had any experience with patch antennas or
high dielectric materials?  I am looking to see if it's even possible for an
antenna to work properly with such a high constant.  Note that bandwidth and
efficiency are not of a huge concern since this is a short range (<100 ft.)
device.  Thanks for any feedback.
