The microstrip patch antenna (MPA) has been in use and has been studied extensively during the past three decades. This antenna, which consists of a metallic patch printed on a dielectric substrate over a ground plane, offers several advantages including ease of design and fabrication; low profile and planar structure; and ease of integration with circuit elements. The minimum dimension of a conventional MPA is in the order of half a wavelength. In recent years, with the advent of new standards and compact wireless devices, there has been a need to reduce the size of this type of antenna. This study discusses some of the principal techniques that have been reported in the literature to reduce the size of an MPA. These miniaturisation techniques include material loading, reshaping the antenna, shorting and folding, introducing slots and defects in the ground plane and the use of metamaterials. The major features and drawbacks of each of these approaches are highlighted in this study along with their effects on the antenna performance metrics.

Nowadays, communications systems have become more mobile and personal, that means materials used must be as smaller as possible. Low weight reduced volume and low cost are some of the characteristics that must be accomplished in modern telecommunication equipment. It is well known that the antenna is one of the most important devices in the radiofrequency (RF) section. This element needs to perform effectively according to the necessities. To achieve low weight, small volume and low cost, the size needs to be reduced, but keeping the main characteristics. The size reduction of antennas can be made by several techniques according to the type of the element. In this study we will present the fundamental limitations of small antennas as a major constraint of antenna miniaturization, then we will discuss major techniques that have been reported in literature to reduce the size of an antenna. Feasibility, features, effects on the miniaturisation of antennas of each technique will be presented and discussed. At the end of this study we will give some examples of real systems that used antennas miniaturization techniques.

“…To maintain the impedance bandwidth (IBW) while reducing the size of a patch by means of higher permittivity, it is required to increase the substrate permeability as well. This theoretical idea has been used for the development of magneto‐dielectric substrate in a goal of squeezing antenna dimension and bandwidth enhancement. With the introduction of metamaterial concepts and the advent of MTMs structures a new dimension in the miniaturization domain has been opened out .…”

In this article, to construct a reactive impedance substrate, unit ring is designed and proposed with radial and concentric mode analysis. A cylindrical substrate backed with a PEC plane and circular metallic elements on the top is used for achieving reactive surface impedance behavior. In this aspect, three unit rings structure with different ring elements are designed and simulated to realize the reflection phase characteristics. Afterwards, a probe‐fed circular patch antenna is miniaturized by stacking the three‐ring circular reactive impedance surface. The fundamental resonance frequency of the proposed antenna is reduced by about 30% with an improvement in impedance bandwidth by 121.6%. An improved front‐to‐back ratio as well as an acceptable co‐pol and cross‐pol isolation is exhibited in both E‐plane and H‐plane at the resonance frequency. In addition of miniaturization, dual band behavior has also been observed in the proposed design. Both resonance phenomena have been explained by circuit model representation and surface current distribution analysis. Improved radiation efficiency at 81.5% has been measured for the proposed antenna configuration.
