“…FDTD analysis of microstrip fed slot antenna has been shown in Reference and ultra wideband antenna with pentagon shaped slot has been discussed in Reference . Only antenna miniaturization has been discussed for different types of antenna topologies. In this research work, we have tried to demonstrate that slot antenna fed by microstrip line can be further miniaturized in comparison with the slot antenna fed by CPW line.…”

In this work, antenna miniaturization using slits and metallic strips fed by microstrip line has been demonstrated. It has been noticed that slot antenna fed by microstrip line provides more miniaturization and in some cases enhanced bandwidth in comparison with the slot antenna fed by other feeding mechanism, keeping the same length and width of the radiating slots, slits and metallic strips. We have achieved 51.67% reduction in resonant frequency and 74.72% improvement in −10 dB bandwidth compared with 37.73% and no bandwidth improvement of either side slits loaded slot antenna topology. Further, it has been shown 63.52% reduction in resonant frequency and 2.23% improvement in −10 dB bandwidth in comparison with 42.33% reduction in resonant frequency of only one side slits loaded slot antenna topology. The current work highlighted not only greater miniaturization and enhanced bandwidth but also almost unperturbed radiation pattern compared to reference antenna topology and low cross-pol level even slot antenna loaded by only one side slits, which was not demonstrated in earlier works.
