Abstract

The dual band microstrip antenna is realized by placing the open circuit stub or by cutting the slot inside the patch. The compact microstrip antenna is realized by placing the shorting post or plate along the zero field line at the fundamental mode of the patch. In this paper, a compact variation of equilateral triangular microstrip antenna, a shorted 600 sectoral microstrip antenna is discussed. Further, dual band antenna realized by placing an open circuit stub on the edges of the shorted 600 sectoral patch is proposed. The analysis to study the effects of stub on the dual band response is presented. The stub reduces the higher order TM21 mode resonance frequency of the patch and along with fundamental TM10 mode yields dual frequency response. Further by studying the surface current distributions at fundamental and higher order mode of the shorted patch, a formulation in resonant length is proposed. The frequencies calculated using the proposed formulations agrees closely with simulated frequencies with an % error less than 5% over the complete stub length range.
