“…Considering the above constraint, the antennas for IoT applications should be smaller and have reduced bandwidth (approximately 1MHz is also supportable for many applications), which is main challenge when designing antennas [3,4]. It has been found that the IoT applications based on various multiband antennas [5][6], and multiband MIMO antenna designs have been investigated [7][8][9][10][11][12][13][14][15][16][17]. A complementary S-shape meander line has been integrated with a slotted rectangular box and capacitive load for WLAN application, showing a gain 1.347 dBi and a radiation efficiency of 79% [5].…”

A compact DNB-MIMO antenna design and analysis for IoT application was proposed. The antennaradiator consists of 2 L-shaaped quarter-wavelengths and inverted 7-shaped radiators with a microstrip feed line, and partial ground plane with a size of 32 × 15 mm2. This antenna achieves a higher quality factor (Q > 10) and narrow band impedance matching at the central frequencies of 1.8 GHz and 2.4 GHz bands with approximately 8.2% and 6.2% bandwidth respectively. The suitability of the designed antenna for IoT applications is verified through the hosting device model. The proposed 4-port MIMO antenna has an overall size of 60 × 60 ×1.6 mm3, and it is printed on an FR4 substrate. The diversity add comma such as ECC, DG, TARC, MEG, and CCL, are calculated and there values are < 0.19, 9.85 dB, < -25 dB, < -6 dB, < 0.19 bits/Hz/s, respectively, within the limits. The proposed antenna is integrated with the Zigbee module (lowercase) to analyze the performance for IoT applications at 2.4 GHz

“…For this purpose, compact four-antenna elements capable of generating four isolated waves are attractive for the terminaldevice and access-point applications [1]- [7]. For the terminal device, the four-antenna elements backed by a ground plane and having a low-profile structure of about 1 mm to be especially suitable for application in the back cover of the terminal device have been reported [2]- [4], which leads to compact integration of the MIMO antenna and the terminal device.…”

A wideband four-port single-patch antenna for fifth-generation (5G) MIMO access-point application in 3.3-5.0 GHz (41% centered at 4.15 GHz) is presented. The antenna uses a simple square patch of size 42 mm x 42 mm (0.58λ x 0.58λ at 4.15 GHz) mounted 10 mm above a ground plane. To generate four isolated waves in a wide band for MIMO application, the square patch is short-circuited to the ground plane using four simple L-shape metal walls to form four resonant quadrants for the quasi-TM 1/2,1/2 mode excitation. Each resonant quadrant is excited using a slot-coupled probe feed to have dual-resonance behavior with good impedance matching over a wide band. It is obtained that the single-patch antenna can generate four isolated waves in 3.3-5.0 GHz with impedance matching better than −10 dB, port isolation >15 dB, antenna efficiency >80%, and envelope correlation coefficients <0.03. Details of the proposed antenna are presented. An extended design for enhanced port isolation of the proposed antenna is also studied.

“…In [10], the low-profile four-port square-ring patch antenna is proposed for wireless local area network (WLAN) MIMO application and has a relatively narrow band of only about 4% in the 2.4 GHz band. On the other hand, the four-port patch antenna with a square patch in [11] operates in a wide band of 3.3-4.2 GHz (3:1 VSWR, fractional bandwidth 24%) for 5G MIMO application.…”

A low-profile six-port circular patch antenna generating six uncorrelated waves in a wide band of about 5.8-7.5 GHz (based on 3:1 VSWR, fractional bandwidth about 25%) is presented. The antenna thickness is 1.4 mm (about 0.027 at 5.8 GHz), which includes a 0.4 mm thick FR4 substrate with the circular patch printed thereon and an additional 1.0 mm thick air layer to achieve a low-permittivity antenna substrate. The circular patch with a diameter of 40 mm (about 0.77 at 5.8 GHz) is separated into six 60 o -disk sectors by using three linear slots across the patch center and sequentially rotated by 60 o . Each disk sector is short-circuited to the ground plane through three properly located shorting pins. It thus makes the 0.5-wavelngth and 0.25-wavelength resonant modes excited at nearby frequencies to form a dualresonant wide band for each port. Additionally, the six ports in the proposed antenna have their port isolation larger than 10 dB and the corresponding six radiating waves have very low envelope correlation coefficients (less than about 0.02) over the wide band. That is, six uncorrelated waves suitable for MIMO (multi-input-multi-output) operation are obtained. The proposed antenna can find applications for wideband mobile MIMO antennas to cover 6.425-7.125 GHz of the possible new mobile communication band or 5.925-7.125 GHz for the new unlicensed WiFi-6E band.INDEX TERMS Mobile antennas, mobile MIMO antennas, six-port single-patch MIMO antennas, lowprofile six-port patch antennas
