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.

“…1,2 The ever-increasing demand for microwave antennas requires materials with high permittivity and low dielectric loss to minimize device size and to ensure signal integrity. 3 Many microwave ceramic materials with high permittivity (ε r = 20-100) and low dielectric loss, such as MgTiO 3 , (Zr x Sn 1-x )TiO 4 , and BaO-Re 2 O 3 -TiO 2 (Re = rare earth element), have been widely used in miniaturized antennas and resonators. However, antennas with high permittivity can excite strong surface waves, which inhibit the radiation field and narrow the bandwidth.…”

Unique polymer-ceramic composites for microwave antenna applications were prepared via melt extrusion using high-density polyethylene (HDPE) as the matrix and low-density polyethylene (LDPE) coated BaO–Nd2O3–TiO2 (BNT) ceramic-powders as the filler. By incorporating LDPE into the composites via a coating route, high ceramic-powder volume content (up to 50 vol%) could be achieved. The composites exhibited good microwave dielectric and thermomechanical behaviors. As BNT ceramic content increased from 10 vol% to 50 vol%, the permittivity of the composites increased from 3.45 (9 GHz) to 11.87 (7 GHz), while the dielectric loss remained lower than 0.0016. Microstrip antennas for applications in global positioning systems (GPS) were designed and fabricated from the composites containing 50 vol% BNT ceramics. The results indicate that the composites that have suitable permittivity and low dielectric loss are promising candidates for applications in miniaturized microwave devices, such as antennas.

“…Unique enabling features that allow for RF and microwave applications such as miniaturizing antenna size, decoupling proximal high profile antennas and enhancing solar cells efficiency made the artificial magnetic materials (AMMs) popular [7][8][9][10]. As the applications of AMMs in RF and microwave devices are growing, a fast, precise and robust design methodology for AMMs meeting specific properties is more demanding.…”

Abstract-Variety of designs for artificial magnetic materials have been proposed in the literature. In most designs such as split-ring resonators, the inductive and capacitive responses of metallic inclusions are dependent since the area and perimeter of the resonators' geometry cannot be tuned independently. In this work, three generic resonators for the design of artificial magnetic materials are proposed. The resonators are called rose curve resonator, corrugated rectangular resonator, and sine oval resonator. The proposed resonators' patterns are characterized so that their areas and perimeters vary independently. Thus, the geometries are capable of satisfying any realizable combination of area and perimeter designed for an artificial magnetic material with desired properties. Numerical studies are considered showing the effectiveness of the new geometries to fulfil design specifications.
