In this article, the capability of epsilon‐near‐zero (ENZ) metamaterial (MTM) to reduce mutual coupling between densely packed array elements is examined. The results show a reduction in mutual coupling between antenna elements and provide a possible way to reduce the element separation. To verify and confirm the simulation results, a prototype of the proposed ENZ structure incorporating an array of closely implemented patch antennas, 0.12λ L, are fabricated and tested. The array antenna has an overall dimension of approximately 2.66λ L × 1.75λ L × 0.05λ L while achieving an average gain and efficiency of 7 dB and 85%, respectively. Measurement shows that the mutual coupling is mostly better than −20 dB across a broad bandwidth of >2.6:1 (10.5–27.7 GHz).

“…However, the antenna has an overall dimension of 76 × 3.5 × 1.524 mm 3 . In [11], a uni-planar tablet/laptop antenna that operates at GPS/GLONASS/LTE/WWAN bands is presented. The antenna is comprised of a coupled-fed shorting strip and spiral strips and it is able to exhibit dual operating bands of 870-965 MHz and 1556-2480 MHz.…”

In this paper, a low-profile antenna is presented for wideband communication applications. The presented design consists of an I-shaped driven strip and a rectangular ground strip with an open slot in the middle and a steeped lower portion. The measured results demonstrate that the achieved operating band of the proposed antenna has the potential to cover Globalstar satellite phones (GSSP) (1.61–1.63 GHz, uplink), advanced wireless systems (1.71–1.76 GHz, 2.11–2.17 GHz), DCS (1710–1880 MHz), GSM (1800MHz), DCP (1.88–1.90 GHz), DCS-1900/PCS/PHS (1850–1990MHz), WCDMA/IMT-2000 (1920–2170MHz), UMTS (1920–2170 MHz) and long-term evolution (LTE) bands (FDD LTE bands 1–4, 9–10, 15–16, 23–25, 33–37, 39). The designed antenna possessed a very small size of 0.35λ0 × 0.027λ0 at the lowest frequency (S11 ≤ −10dB), achieved good gains and exhibited stable radiation patterns, which makes it suitable for handheld communication devices.

A multiband multiple‐input multiple‐output (MIMO) microstrip patch antenna using complementary split‐ring resonator (CSRR) structure is proposed for Global System for Mobile (GSM) and Long‐Term Evolution (LTE) applications. The proposed antenna consists of two radiating patches with folded microstrip lines and symmetric L‐shaped slots, which are connected together with an isolation line for reducing the coupling effect between ports. CSSRs are used to enhance the isolation and to control resonant frequencies. Radiation elements of the antenna are designed for various applications such as GSM (900 MHz) and LTE (1900/2300/2600 MHz). The proposed antenna is fed by 50 Ω CPW lines. Various parameters calculated in this antenna show a return loss and an isolation of less than −10 dB and −15 dB respectively. Moreover, the gain of 2.8dBi and the radiation efficiency of 72% have been obtained for proposed antenna. The presented antenna occupying 60 × 70 × 0.8 mm3 is implemented on an FR4 substrate.
