Software comparative study for RF power coupler

Novel Conception of a Tunable RF MEMS Resonator

“…Two electromagnetic software's (HFSS and CST MWS) are used and their computing methods are respectively the FEM method and the FIT method [16]. The return loss and the insertion loss are presented in figure 2.a and b respectively, and the comparison between the two simulation results using two different simulator HFSS and CST illustrates a small variation (< 2.5db).…”

“…The figure 5 shows the simulation result of the deflection of the bridge at pull in voltage equal to 37.4 V. In the above obtained results, we observe that the RL of the classical RF MEMS does not have almost any values under -30 dB; but for the proposed resonator has the less return loss, than -30 dB is present in the bands . Also, in terms of frequencies bands, we have a significant single usable ultrawide band [10][11][12][13][14][15][16][17][18][19][20][21][22][23][24][25][26][27][28][29] for the proposed resonator in spite of two frequency bands [10][11][12][13][14][15][16][17][18][19][20][21][22][23][24][25][26][27][28][29], [10][11][12][13][14][15][16][17][18]…”
