The design of a miniaturized slot antenna fed by microstrip line is proposed based on loop, slit, and strip loading techniques. The antenna topologies considered are different combination of loops, slits, and strips on top and bottom of the substrate. It is found that the antenna topology with proper combination of slit and loop on top of substrate and strip on bottom of substrate provides 48.01% reduction in resonant frequency unlike only loop or slit on either end of slot antenna fed by coplanar waveguide. It is also observed that the radiation characteristics of loaded antenna are almost similar to that of unloaded antenna, with low cross polarization and -10 dB bandwidth of miniaturized antennas are also enhanced more than 60% compare to the unloaded antenna topology in all the three cases.
