Abstract
The areas of application of EAS systems are, among others, stores and libraries. EAS systems are used to signal a theft of goods. The exemplary EAS system consists of: a transmitting antenna, a receiving antenna and tags also called clips. The tag is an element of the system with which the consumer has direct contact. The tag can be installed on various items available in the store. Starting from the size of a pen, through jackets and coats to TVs and bicycles. Therefore, the aesthetics, and mainly the size of the tag, cannot distort the consumer's ability to check an item accurately, nor can they affect its use. The paper presents a method of minimizing the dimensions of a tag while maintaining the required detection distance.

Summary
Transmitting and receiving antennas are mounted at the exit of the protected zone in which protected goods with attached tags are located. Employees of the protected zone deactivate or remove tags when the item is properly purchased or rented. An alarm will be triggered when an active tag is near antennas [1]
