Modeling of resonance frequency in rectangular microstrip antenna using transmission line model

In this paper, the accurate equation has been presented to calculate the resonance frequency of the rectangular microstrip patch antenna. This equation has been achieved using transmissionline model of the microstrip antenna. Although differences between presented equation and previous equations areinsignificant, the new approach gives better insight to calculate the resonance frequency while addition lumped component has beenloaded to the antenna patch. Presented equations result shows the good agreement with simulation results. More over the resonancefrequency changes due to the various patch‟s width and length are discussed to achieve appreciate rang of proposed equation
