During the past years, the patch antenna had been studied and used extensively worldwide and with various types of wireless communication devices. The design of the patch antenna consists of three layers placed on each other. The first layer is called the patch which it made of metallic material. The second layer is the substrate which it made of dielectric material. The last layer is ground plane, it made of metallic material also. This type of antenna has some merits like ease of integration with electronic circuit components. Lately, the world of communications has witnessed a great development in terms of the inclusion of some devices, such as tablets, smart watches and mobile phones, on multiple technologies in addition to the basic function of these devices. Therefore, the urgent need to reduce the components of these devices is located. Some of the main techniques that have been recently studied by researchers for the size reduction of antenna are discussed in this paper. The most important of these techniques include making defects and slots in the ground plane, shorting and folding, material loading, and reshaping the antenna. Also, each technology was discussed separately, and the main defects of each technology and its advantages were presented, and the impact of each technology on the performance of the antenna was also highlighted.
