A flexible antenna with high robustness is presented for wireless body area networks (WBANs) in-body communications. The coplanar waveguide (CPW) fed hexagon slot structure is employed to obtain a wide bandwidth of 34.4%. A parasitic patch is used to enhance in-body gain to -3.36 dBi. With these advantages, the proposed antenna is insensitive to frequency shift and gain reduction caused by environmental changes. Besides, the proposed low-profile antenna on a flexible substrate is well fit for wearable applications.
