“…e physical dimensions of the antenna systems at mmwave become critically smaller; also, the wavelength becomes critical to fading environments. A four-port antenna system is presented in [5] with conical rings for e antenna elements are well isolated offering pattern diversity characteristics, but the gain of the MIMO system is very low. Similarly, a natureinspired four-element MIMO antenna in [6] offers pattern and spatial diversity characteristics, but the bandwidth of the antenna is very low.…”

In this research, a novel T shape antenna is proposed for millimetre-wave (mmwave) 5G systems. Designed on 0.254 mm thin Roggers 5880 substrate with a dielectric constant of 2.3 and the loss tangent of 0.0009, the proposed antenna offers a wideband characteristics of nearly 8 GHz with gain of 4.25 dBi for single element. Based on these characteristics, the single element is further constructed into a four-element linear array with a compact size of 18.5 × 24 mm2 The proposed antenna array exhibited dual beam radiation patterns with a high realized gain of 11.5 dBi and 94% efficiency. The measured results from the fabricated prototype well agree with the simulated results and thus, therefore, make the proposed antenna system a well-suited candidate for future mmwave devices.

“…However, the achieved gain is not suitable to tackle the atmospheric attenuation challenges at the desired band. Similarly, a four-port infinity shell-shaped antenna array was presented by Kamal et al [9] at 28 GHz having maximum gain of 7 dBi and ECC less than 0.15 over the entire band of interest. However, the gain of the proposed system is comparatively less for MIMO systems.…”

To address atmospheric attenuation and path loss issues in the mmwave portion of the spectrum, high gain and narrow beam antenna systems are essential for the next generation communication networks. This paper presents a novel hook-shaped antenna array for 28 GHz 5G mmwave applications. The proposed antenna was fabricated on commercially available Rogers 5880 substrate with thickness of 0.508 mm and dimensions of 10 × 8 mm2. The proposed shape consists of a circle with an arc-shaped slot on top of it and T-shaped resonating lengths are introduced in order to attain broad band characteristics having gain of 3.59 dBi with radiation and total efficiency of 92% and 86% for single element. The proposed structure is transformed into a four-element array with total size of 26.9 × 18.5 mm2 in order to increase the gain up to 10.3 dBi at desired frequency of interest. The four-element array is designed such that it exhibits dual-beam response over the entire band of interest and the simulated results agree with fabricated prototype measurements. The proposed antenna array, because of its robustness, high gain, and dual-beam characteristics can be considered as a potential candidate for the next generation 5G communication systems.

“…In [15] authors presented a simple planar array with narrow beam width characteristics. In mmwave antenna arrays and MIMO configurations, the isolation enhancement can be achieved using different techniques such as orthogonal placement, slotted stubs, metamaterials and Electromagnetic band gap (EBG) structures [16][17][18][19][20][21][22]. In arrays the inter-element spacing can be kept at 1λ distance to avoid coupling.…”

In this work, a compact, light-weight, low-cost, and easy install and incorporate mmwave printed square loop antenna with a perturbed ground plane is proposed. The antenna is fabricated on an ultra-thin 0.254 mm Rogers RT/Duroid 5880 substrate. The antenna resonates between 26 GHz and 40 GHz providing the broad bandwidth of 13 GHz (~47%). First, a single element consisting of three rectangular square loops and a transmission line with total dimensions of 9 mm x 11 mm (0.84 λ0 x 1 λ0) is designed. The loop elements are arranged on top of each other and with the further insertion of square slot in ground plane, wideband resonance response has been achieved. The antenna demonstrates gain of more than 3.3 dBi, and radiation and a total efficiency of 98% at 28 GHz. The proposed design enables spatial diversity and minimize the effects of interference between adjacent channels by providing dual-beam within desired frequency band. In addition, a linear array (18.5 x 22.5 mm 2 ) of four elements with a traditional feeding network is also designed, simulated, and measured. The gain of the array is 10.1 dBi, while the radiation and the total efficiency is more than 92 % at 28 GHz. A brief literature review and comparison of this work with other published works is also presented. To validate the proposed design and concept, a prototype is fabricated for both, a single element, and an array. It is found that the measured results and the computed results are in good agreement. Therefore, we believe that this system will find its applications within modern mmwave communication cellular devices.
