A compact Umbrella shaped Stretchable with Circular Slots for Bio-medical applications

There is wide application of wearable products and devices in biomedical field and even the usage is increasing exponentially. The antenna presented here is suitable for monitoring, alerting and demanding attention during any hospital emergency. This ultra-wide band (UWB) flexible umbrella shape body worn antenna is fabricated on a jean’s material as a substrate. The incarnated antenna has a - 10dB measured impedance band width of 1309MHz.The antenna size is 64.2 × 77.2 mm
