433mhz microstrip antenna

hello!

i need to design a 433 MHz patch antenna and i would like to know what is the best design to made it.

recctangular patch, or printed dipole?

thnak you for any help.

best regards

433MHz is relative low frequency for a microstrip antenna (70cm wavelength) and patch or dipole will be too large. I would recommend a modified Inverted-F, or small loop, or meander antenna, if you want to go microstrip at this frequency.
