Wireless sensor networking is a rising innovation that has a wide scope of potential applications. Such a system ordinarily comprises an enormous number of conveyed nodes that sort themselves out into a multi-​hop remote network. Every node has at least one sensor, implanted processors and low-​control radios, and is ordinarily battery operated. A cognitive radio (CR) is a radio that can be modified and designed progressively to utilize the best remote diverts in its region to stay away from client obstruction and blockage. The cognitive procedure is the way toward knowing through recognition, arranging, thinking, acting, and ceaselessly refreshing and updating with a background marked by learning. CR can know the unutilized range in a permit and unlicensed range band, and use the unused range sharply. The primary users (PU) reserve the option to utilize the range whenever secondary users (SU) can use the range just when the PU isn’t utilizing it.

Such a system ordinarily comprises an enormous number of conveyed nodes that sort themselves out into a multi-​hop remote network. Every node has at least one sensor, implanted processors and low-​control radios, and is ordinarily battery operated [1]. A cognitive radio (CR) is a radio that can be modified and designed progressively to utilize the best remote diverts in its region to stay away from client obstruction and blockage. The cognitive procedure is the way toward knowing through recognition, arranging, thinking, acting, and ceaselessly refreshing and updating with a background marked by learning.

The primary users (PU) reserve the option to utilize the range whenever secondary users (SU) can use the range just when the PU isn’t utilizing it. Different wearable antennas have been proposed and presented in the last few years.

Broadly, they can be classified into the following categories:

1) Wearable patch antennas
2) Wearable antennas loaded with metamaterial structure
3) Coplanar waveguide (CPW) fed wearable antennas
4) EBG structure based wearable antennas
