A simple and compact planar printed monopole antenna for ultra wideband application is presented. The proposed antenna comprising of bevel slots in the lower parts of the antenna with annular ring slot. Partial ground plane has been used to enhance the impedance bandwidth. The simulated results show that the proposed antenna exhibits UWB for 2.7 GHz to 11.22 GHz with -10dB return loss and VSWR < 2. Antenna gain and radiation pattern plots for different frequencies are also investigated. The performance characteristics of the proposed antenna are simulated using Ansoft HFSS.

Sensor network have since been considered a promising alternative to complement conventional monitoring processes. These networks are relatively affordable and allow measurements to be taken remotely, in real-time and with minimal human intervention. we are going to use a under -water Wireless sensor network system which can transfer multiple data from one place to another while being attached to an Autonomous underwater Vehicles (AUV) while submerged in water. The concept of transferring data is based on two main components name as Transmitter and Receiver. It can transfer the signal underwater without Internet connection here, the depth of the water in which it can transfer the signal depends on the transmitter module. It has Alarm Sensors system that will get activated if there some disturbance with AUV. It can be used in multiple purposes for both commercial and militarily like Navy
