what more can i do with my rfid microstrip antenna?

hi! i have designed and fabricated a uhf microstrip antenna for rfid tag for my undergraduate fyp. i need ideas to expand it for my master degree thesis. thank u

I trying to make an RFID antena but for a reader not for a tag, can your antenna could be made bigger and be used as a reader antenna?

hi.
you shoud'nt use antenna for tag because of the tag is be expensive.
you should design agood antenna for reader for example you can use fractal antennas.
for tag you can use a simple antenna for example a simple coil.

The usual themes for "improving" antennas include:

reduce the cost
reduce the size
increase the sensitivity (sometimes gain, sometimes efficiency)
reduce s11
make it less sensitive to the environment
make it stronger
make it usable in more applications
