“…Both resonances have gone down slightly to 2.32 GHz and 4.78 GHz because of the longer current paths on the patch because of the slots as shown in Figure 7. This fact of using slots to enforce longer current paths has been useful to design small microstrip antennas [23][24][25][26][27]. In addition, due to the different sizes of the slots the two resonances are away from each other.…”

Abstract-Nowadays the mobile personal communication systems and wireless networks are commonly used. Experience has revealed that the antennas suitable for these applications should have small size and operate in assigned different frequency bands. For this purpose, circularly polarized (CP) multiband square microstrip antenna with three N-slots and a pair of truncated corners is proposed, designed and simulated. To reduce the losses and improve the antenna efficiency in addition to the bandwidth, an efficient electromagnetic band gap (EBG) structure is introduced. The proposed antenna has produced a higher efficiency, an improved operational bandwidth, and a higher gain relative to the conventional microstrip antenna.

“…This method is widely used to miniaturize the Micro Strip Patch Antenna (MPA), several works [27][28][29][30][31][32][33][34][35][36][37][38][39] have appeared in the literature in which the size of the MPA has been reduced by introducing various types of slots in the MPA. The use of this method generally leads to poor polarization purity.…”

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.

“…(Anguera et al, 2003b). Another technique to increase the directivity is the use of stacked patch antennas (Anguera et al, 2004). In addition to the above, high-directivity antennae based on superstrates (Foroozesh & Shafai, 2012 Jayasinghe et al (2013a;b) propose the design of a high-directivity microstrip patch antenna to replace a 2 × 1 and a 4 × 1 conventional patch arrays by avoiding feeding networks.…”

Conventional single element microstrip patch antennae have a . In order to increase the directivity, an array of microstrip patches can be used. It may be possible to further improve the performance of arrays by applying genetic algorithms (GA). This paper presents a method to increase the directivity of a 2 × 1 patch array with broadside radiation using GA. The proposed GA method divides the patch area into different cells, taking into account that cells have a small overlap area between them. The patch array is etched on a substrate with a relative permittivity of 3.38 and a thickness of 1.52 mm. The antenna operates at 4 GHz resulting in a directivity of 10.9 dB. The specialty of this design is the use of GA to select the inter-element spacing, optimized shape and the feeding position instead of a known shape and a fixed inset length of feeding. The results show that the directivity of the genetic array is larger than that of the conventional array with the same overall dimensions, which resonates at the same frequency.
