Due to the rapid development of wireless communication systems, good numbers of services and devices use different frequency bands and protocols. To concurrently cover all these services, the antenna in communication devices should operate over multiple frequency bands. The use of wide and multi-band antennas not only reduces the number of antennas necessary to cover multiple frequency bands but also lessens the system complexity, size, and costs. To operate over eight frequency bands to cover sixteen well-established narrow service bands, a planar monopole antenna is proposed for portable communication devices. The proposed antenna is comprised of an inverted F-shaped monopole patch with a rotated L-shaped strip and an F-shaped ground strip with a rotated L-shaped branch. The studied antenna can excite at multiple resonant modes which helps it to achieve eight measured operating bands of 789–921 MHz, 1367–1651 MHz, 1995–2360 MHz, 2968–3374 MHz, 3546–3707, 4091–4405 MHz, 4519–5062 MHz and 5355–6000 MHz. The achieved measured operating bands can cover sixteen popular narrow service bands for 4G/3G/2G, MWT, WiFi, WiMAX, WLAN, and sub-6 GHz 5G wireless communication system. The studied antenna achieved good gain, efficiency and exhibits stable radiation characteristics. Moreover, the antenna does not use any lumped element and left ample space for other circuitries which makes it easier to use in portable devices such as tablets, laptops, etc. with low manufacturing cost.

“…By using the 0.25 wavelength mode of a coupled line, the size of an antenna can be reduced and the bandwidth can be enlarged. The single antennas in References 22 and 23 also use the coupled feeding method to realize their broad bands. By using the 0.5 wavelength slot mode, the current distributions of the antenna are more balance and it is beneficial to improve the bandwidth.…”

A wideband eight-element antenna based on slot modes for 5G metal frame mobile phones is proposed. The proposed antenna has two kinds of elements that both have four elements. Both kinds of elements consist of a coupled line and a closed slot. The slot sizes of the two kinds of elements are 26 mm × 2.5 mm and 28.5 mm × 2.5 mm, respectively. The measured working bands (under the condition of the reflection coefficients smaller than −6 dB) of the two kinds of elements are 3.3 to 5 GHz and 3.3 to 4.2 GHz, respectively. The eight elements can form an eight-element MIMO antenna system working at the band of 3.3 to 4.2 GHz and a four-element MIMO antenna system working at the band of 3.3 to 5 GHz. For the first kind of elements, the measured gains at the working band of 3.3 to 5 GHz are 2.23 to 4.29 dBi. For the second kind of elements, the measured gains at the working band of 3.3 to 4.2 GHz are 1.83 to 3.95 dBi. At the working bands, the measured isolations and efficiencies are bigger than 10 dB and 45%, respectively, the envelop correlation coefficients (ECCs) are smaller than 0.26, and the ratios of mean effective gains (MEGs) are smaller than 1.26 dB. With a 20 dB signal-to-noise ratio (SNR), at the band of 3.3 to 4.2 GHz, the ergodic channel capacity of the proposed eightelement MIMO antenna system in an 8 × 8 MIMO system is 36.5 to 37.8 bps/ Hz; at the band of 3.3 to 5 GHz, the ergodic channel capacity of the proposed four-element MIMO antenna system in a 4 × 4 MIMO system is 18.5 to 19.6 bps/Hz.

In this paper, a wideband eight-element antenna array operating in the 5G (Fifth-generation) NR (New Radio) frequency bands N77/N78/N79 (3300-5000 MHz), LTE (Long Term Evolution) band 46 (5150-5925 MHz), and EU (European Union) 5G band of 5900 to 6400 MHz for 8 × 8 MIMO (Multi-Input Multi-Output) operation in the future 5G mobile terminal is presented. The proposed eight antenna elements are all co-coupled-fed IFA (Inverted-F antenna)/loop structure, and are divided into two same sub-arrays which printed on the inner surface of two long frames of the mobile terminal, respectively. All the simulated and measured results present consecutive 6-dB impedance bandwidth of 3200 to 6500 MHz, acceptable isolations (better than 12 dB), and good total efficiencies (more than 50%). Besides, the proposed wideband 8-antenna MIMO system has also shown good MIMO performances with ECCs (envelope correlation coefficient) are all lower than 0.08, and ergodic channel capacities are all higher than 37.8 bps/Hz within the entire desired operation bands. In addition, the hand phantom effects are also investigated. The prototype of the proposed wideband eight-element antenna array is fabricated and measured, and a quite good agreement between simulation and measurement is obtained.
