“…Recently, there are many techniques that have been used in the literature to reduce the mutual coupling between antennas, and much effort has been devoted to minimizing the size of microstrip antennas such as using a dielectric substrate of high permittivity [3]. In [4][5][6][7][8][9], the mutual coupling between ports can be reduced by using defected ground structures (DGS) at the ground plane. In other words, the utilization of electromagnetic band gap (EBG) structure has the ability to enhance the isolation as well as increase the MIMO antenna performance [10][11][12].…”

In this paper, a compact planar mono-band multiple input multiple output (MIMO) antenna with four monopole elements is presented for X-band satellite applications (7.2-7.8 GHz). The MIMO antenna resonates at 7.5 GHz, with high isolation (more than 26 dB) between its ports. It consists of a four closely arranged symmetric monopole antennas with edge-to-edge distance of 7.2 mm (0.18λ). In the top face, different forms are loaded at the rectangular patch. A U-shaped slot defected ground structure (DGS) has embedded in the ground plane. The prototype of the proposed MIMO antenna is simulated, fabricated, and measured to examine the performance of this antenna in terms of S parameters, radiation patterns, envelope of correlation coefficient (ECC), and diversity gain (DG). As a result, the presented antenna has a high isolation (S 12 < −26 dB) at 7.5 GHz with an impedance bandwidth of 430 MHz (7.28 GHz-7.71 GHz), which covers the X-band applications. The diversity gain is about 10, and the envelope correlation coefficient of antenna is less than 0.02 which means that the antenna has high performance at the resonance frequency.

“…The antenna system, being the front end of all hand-held communication devices is expected to cover all major frequency bands of IEEE 802.11 (2. enough to regulate impedance bandwidth for various center frequencies independently [4]. Some well-known techniques such as slots in the radiating patch, defected ground structures (DGS), engraving strips on antenna, and the induction of band notched structures in the designs have been adopted to satisfy the abovementioned characteristics [4,5]. Apart from these orthodox methods, the use of metamaterials and complementary split ring resonator (CSRR) techniques are employed in literature for getting higher gain in order to reduce cross frequency interference.…”

“…Various CPW-fed antennas have been reported in literature such as multiband [3][4][5][6][7][8], CPW antennas with added strip for WLAN [9][10][11], and asymmetric coplanar strip antennas [12][13][14][15][16][17][18][19][20]. However, majority of these designs have large antenna dimensions and do not cover all the major bands of WLAN/WiMAX/LTE [13][14][15][16]18].…”

This paper presents a dual-band coplanar waveguide (CPW) fed printed antenna with rectangular shape design blocks having ultrawideband characteristics, proposed and implemented on an FR4 substrate. The size of the proposed antenna is just 25 mm × 35 mm. A novel rounded corners technique is used to enhance not only the impedance bandwidth but also the gain of the antenna. The proposed antenna design covers two ultrawide bands which include 1.1-2.7 GHz and 3.15-3.65 GHz, thus covering 2.4 GHz Bluetooth/Wi-Fi band and most of the bands of 3G, 4G, and a future expected 5G band, that is, 3.4-3.6 GHz. Being a very lowprofile antenna makes it very suitable for the future 5G Internet of Things (IoT) portable applications. A step-by-step design process is carried out to obtain an optimized design for good impedance matching in the two bands. The current densities and the reflection coefficients at different stages of the design process are plotted and discussed to get a good insight into the final proposed antenna design. This antenna exhibits stable radiation patterns on both planes, having low cross polarization and low back lobes with a maximum gain of 8.9 dB. The measurements are found to be in good accordance with the simulated results.

“…As a result, several works have recently been dedicated to internal multiband antennas in mobile handset applications. The planar Inverted-F antennas (PIFA) [2], [3], microstrip patch antennas [4], [5] and monopole printed structures [6], [7] have been considered as the most common internal mobile phone antennas. In particular, with the advancement of the LTE technology, smart phones are now broadly used, thus designing new antennas for legacy and future release of the LTE standard, catering for carrier aggregation and multiple wideband frequency bands are now of much interest in the research community.…”
