“…A larger frequency range (>24GHz) is necessary for the exceptionally fast data transfer speeds of 5G and later communications [23]. The designed antenna sensor operates in the higher frequency band (>32 GHz) which is very high compared to some recent works [24]- [26]. At the resonant frequency of 33.29 GHz, the VSWR is 1.31, making it an ideal system for stable 5G and beyond wireless communication.…”

“…Therefore, the antenna system is better suited to the requirements of 5G and beyond communication technologies due to its higher frequency band operation and improved reflection coefficient. As the proposed design is very tiny, therefore, it can be incorporated with nextgeneration compact thin smartphones with multiple array elements for multiple-input multiple-output (MIMO) communication [25], [26]. The proposed antenna model has the significant potential to detect early-stage malignant in breast fantom.…”

“…It is also more convenient in 5G and beyond communication applications by making 10 or more elements of the array of the proposed prototype unit cell [26] because it is very small in size with better gain and efficiency compared to recent studies. It can be done by just duplicating the single-element antenna as the design is very convenient and simple.…”

Breast cancer is one of the deadliest forms of disease that affects women worldwide. X-ray mammography, magnetic resonance imaging, and ultrasound are all helpful methods of medical imaging, but they have their own limitations due to low tissue contrast and side effects. Millimeter wave (mmWave) imaging has been offered as a viable alternative to the conventional screening methods due to their drawbacks. Without exposing the patient to ionizing radiations, malignant lesions can be detected by using the dielectric discontinuities in the tissues. The purpose of this work is to develop a simple, low-cost miniaturized mmWave imaging antenna sensor that can be used to detection of breast tumors or cancers in women by monitoring the changes in the antenna's S11 parameter. The dimension of the proposed rectangular mmWave antenna is 5 mm × 5 mm × 0.578 mm. The proposed antenna sensor has an operating frequency band range of 32.626 GHz to 33.96 GHz with a peak gain of 6.65 dB and an efficiency of 91.46% in terms of radiation which makes it a suitable system for fifth generation (5G) communication. As well as the antenna sensor can detect very tiny malignant that size ≥1 mm inside the breast fantom.

A low-profile planar multiple-input multiple-output (MIMO) antenna consisting of four elements with isolation improvement is proposed for 5G mm Wave (24–40) GHz applications. Each radiating element of the MIMO antenna comprises of a microstrip-fed tilted spade-shaped radiator with four asymmetrical slots and a partial ground plane. The antenna is optimized to resonate at 35 GHz covering a wide impedance bandwidth from 23.9 to 40.1 GHz. Two cross lines are then loaded between the antenna elements to improve the isolation > − 30 d B . The MIMO structure with the decoupling lines is fabricated and tested. The measured results are in good correlation with the simulated results. Other MIMO performance metrics such as the envelope correlation coeﬃcient (ECC), channel capacity loss (CCL), diversity gain (DG), and total active reflection coefficient (TARC) are examined, and the results are found to be satisfactory for the device to be used for mm-wave 5G MIMO applications. Also, the antenna’s performance metrics such as radiation efficiency, gain, and radiation patterns over the operating band are presented.

“…CR performs dynamic spectrum management and thus increases the spectral efficiency. Because of the scaling down of wireless circuits, the need of next generation technologies like LTE with higher data rates is growing day by day [11][12][13][14][15][16][17][18]. So, designing a compact MIMO antenna to cover sub-1 GHz bands like LTE 700 without increasing the antenna size and decreasing its performance is one of the design challenges.…”

A 4-port planar multiple-input multiple-output (MIMO) antenna system design is proposed. The antenna elements are modified meandered wideband antennas which cover frequencies from 674 MHz to 1 GHz, 1.9 GHz to 2.1 GHz, 3.175 GHz to 3.476 GHz, 4.529 GHz to 4.761 GHz, and 5.254 to 5.513 GHz for long term evolution (LTE), Internet of Things (IoT), and sub-6 GHz applications and thus can be used for robotic navigation, logistics, healthcare, tracking, transportation, etc. Due to very small envelope correlation coefficient (ECC) between the ports (< 0.5), the MIMO configuration can be efficiently implemented which helps in increasing the data rates. It is very compact in size and thus can be used for portable handheld devices. Since there is the problem of current localization due to common ground, the future work aims at minimizing coupling and improving the impedance matching using novel decoupling networks. These MIMO antennas are connected to a common slotted ground plane. Antenna simulation has been done using Computer Simulation Technology (CST) Microwave Studio Suite simulator. A low cost FR-4 substrate with dimensions 65 mm × 90 mm × 1.6 mm has been used for antenna fabrication, and experimental results are obtained using an anechoic chamber and a vector network analyser. ECC and realized gain of the antenna are also obtained experimentally and are almost similar to the simulated results.
