Effective design of an integrated filtering antenna for body area networks in ISM band

Body-area networks (BAN) are used in applications such as smart health monitoring, elderly care and biotelemetry. In the bio telemetric system decisive component is wearable antenna that aid off body communication. work undertaken, circularly polarized rectangular patch integrated with microwave band pass filter (BPF) circuit realized using fourth order hairpin line resonators. The filtering operating at 2.45GHz ISM realizes an s11<-21.24 dB bids superior selectivity. designed compact filtenna can be devices, placed close propinquity to of human beings a nominal specific absorption rate (SAR) having fewer electromagnetic impression on body. simulation performed tool ANSYS HFSS.
