The main goal of this work is to create an application that has the ability to communicate, connect, and control physical entities via the Internet. This purpose can be achieved by the Internet of Things or Internet of everything (The more complete form) which is a new revolution of the Internet to allow objects to be connected to the internet. Connected objects can communicate with each other or with us via an HTML interface that allows to create a communication between the user and the server ESP8266 through its IP address. Objects have been connected wirelessly (WiFi communication). A sensor is used to collect data then transfer it to the user via the Internet in order to make correct decisions in anywhere at any time.

In this paper a Metamaterials Reconfigurable Multiband Antenna is designed. The design consists of a rectangular patch antenna surrounded by an arrangement of cross shaped metamaterials cells that have two different behaviours and can be controlled electronically in order to switch between the two different behaviours; therefore, the antenna will have a controllable size according to the surrounding area behaviour. The obtained results show that the antenna operates at different frequencies. We demonstrate the possibility to design a metamaterials based frequency agile antenna.
