What is it about?
The antenna is smaller in size and providing a large bandwidth with an excellent radiation pattern and good peak gain value. It is suitable for mobile applications.

Why is it important?
This work presents a compact wide-band metamaterial antenna with three resonant mode. Each resonant mode can be controlled separately.By merging all the modes wide-band phenomena is achieved. This work introduces a new type of inter-digital capacitance, which provide better matching with slightly enhanced bandwidth. Gain which is a important parameter for any antenna is positive and acceptable through-out the bandwidth.
Perspectives
This publication introduces a new type of inter-digital capacitance, which is responsible for little bandwidth enhancement. The key feature of this work is it's compactness and wide-band bandwidth which is achieved by merging the number of modes. This is a short ended antenna and all the resonant modes can be controlled separably, which make it interesting. Some other features like excellent radiation pattern, radiation efficiency with good gain make it suitable for mobile applications.
