A review on Miniaturization techniques for microstrip patch antenna

Electronics and Communication Engineering

Microstrip patch antenna (MPA) has become an integral part of wireless communication system because of their advantages such as low profile, light weight, available with planner and non-planner structure. The increasing growth of wireless system requires miniaturized antenna. Conventional antenna size is about half wavelength. With the development of the technologies wireless systems becoming more and more compact so antenna size must have been reduced. This study shows some of the techniques to reduce size of microstrip patch antenna. This miniaturization techniques include use of high permittivity єr materials, use of meta- materials, Sierpinski carpet fractal method, using pins between patch and ground plane, introducing slots in the patch. The major features and drawbacks of these methods are highlighted in this study.
