Recent days, the concept of data mining and the need for it, its objectives and its uses in various fields, explain its procedures and tools, the type of data that is mined, and the structural structure of that data while simplifying the concept of databases, relational databases and the query language. Explain the benefits and uses of mining or mining data stored in specialized databases in various vital areas of society. Also, it is the process of analyzing data from different perspectives and discovering imbalances, patterns and correlations in data sets that are insightful and useful for predicting results that help you make a good decision. Let's bring back our mining example, when you plan to prospect for gold or any valuable minerals you first have to determine where you think the gold is to start digging. In the process of data mining we have the same concept. To mine data, you must first collect data from various sources, prepare it, and store it in one place, as nothing from data mining is related to the process of searching for the data itself. Currently, the company is storing data in what is called a Datawarehouse which we will talk about in a later stage in detail.

Recently the demand for compact size devices has been increased whether being used for sensor networks, smart phones, smart watches or RFID tags etc. One of the most important parts of these systems is its antenna which facing a big challenge of having a low profile that meets the required size of these wireless communication devices. This paper presents a design of a simple planar strip monopole antenna for WLAN application.Miniaturization has been performed on this antenna via two different techniques. Firstly corrugations were added to both side edges of the radiating strip that reduced the size with 10.7% of the original size. Secondly the radiating strip has been meandered to increase the size reduction to about 14.28%. Both simulation and measured results shown that meandering technique was more efficient in miniaturizing the size of the designed antenna due to forcing the current to follow a meandered path that rise up with shorter height.
