The proposed antenna has a simple structure and small antenna size of 46.8 mm x 74 mm or 0.137 Lambda0 x 0.217 Lambda0 at 878 MHz resonant frequency. Advanced Design System (ADS) software is used to develop the antenna circuit model. Each section of the antenna structure is represented by the inductance and capacitance circuit with their values are depending on the width and length of the structure. The circuit model is developed based on common discontinuities in the microstrip line. The performance of the circuit model in terms of return loss is compared with the CST simulation for a validation. The printed monopole antenna is having similar radiation characteristics as an ideal wire monopole where it radiates uniformly in all directions. ER -
