Dual band microstrip patch antenna for wireless applications at 5.2 GHz and 5.8 GHz using CSSRR

Dual band CSSRR inspired microstrip patch antenna for enhancing antenna performance and size reduction

“…In the present work, To achieve dual-band operation using metamaterials here in this design capacitive matching is used instead of previously inset fe ed matching [7,8]. CSSRR in comparison to CSRR does not disturb current in dominant mode hence provides good radiation pattern.…”

“…Both CSSRR's resonate at 5.2 GHz and for 5.8 GHz patch resonates and some part of CSSRR also resonates [7]. Gap coupling provides matching of power from port to patch antenna through microstrip line while a via is introduced in center of patch to ground and it provides capacitive matching [7]. A good E-plane and H-plane radiation pattern at 5.2GHz and 5.8 GHz is shown in Figure 6(a) and (b) in addition back lobe is very small.…”

“…Figure 3 shows the surface current distribution of the antenna at center frequency 4.7 GHz. Surface current distribution or current density gives the better understanding of the antenna behavior at the desired frequency [13][14][15]. It gives the better understanding about which part of the antenna is resonating.…”
