DESIGN OF WEARABLE MICROSTRIP PATCH ANTENNA FOR WBAN APPLICATIONS TO ENHANCE BANDWIDTH USING MULTIPLE SLOTS AND CRR

This paper deals with the investigation of bandwidth of wearable micro strip patch antenna with slots are created on patch and CRR underneath. This technique overcomes the problem of narrow bandwidth of MPA. Here, wearable patch antenna designed to operate at 2.3 GHz with slots on patch and CRR to widen bandwidth. The micro strip transmission line feeding is used to connect the patch with 50 Ohm SMA connector. To illustrate working of proposed antenna, simulated with flat and bend surface using CST studio. The flexible substrate material used for this antenna is 10mil with dielectric constant of 2.2 and substrate height of 0.036mm.
