In current telecommunication situation,the antenna with wideband or multi-band effect are important for cater many users’ demands.In this research,the works explores the effect of parasitic element on the above of the dual layer microstrip patch antenna.Firstly,a basic microstrip patch antenna with a single layer of substrate (Design A) had been simulated using the CST Microwave Studio software.After that,the addition of another layer of substrate with parasitic element is shown as Design B. This proposed microstrip patch antenna resonates at two different frequencies of 2.396 GHz and at 2.543 GHz of frequency with – 36.8 dB and –35.644 dB of return loss,respectively.The gain performance for both resonant frequencies at 2.396 GHz and at 2.543 is 5.035 dB and 4.814 dB,respectively.The bandwidth of the Design B antenna is 0.097 GHz (2.354 GHz – 2.451 GHz),had been increase compare with Design A performance of 0.039 GHz (2.380 GHz– 2.419 GHz).The second resonant frequency for Design B is only 0.028 GHz.(2.526 GHz– 2.554 GHz).
