I realized that the microstrip patch antenna size can be reduced for the same frequency if we use a very high dielectric substrate such as ceramic and etc. I would like ask that is this concept applicable to very small microstrip patch antennas, possibly micron or nano level sized antennas ?
If I used a very high dielectric material as substrate for the radiating patch, is it possible for me to reduce the size of the antenna to micron level while maintaining the frequency ? I would like to use the antenna is for biomedical applications.
