“…Planar MIMO topologies studied include slot, defective ground structure, coplanar waveguide (CPW), tapered/Vivaldi, meta surface/metamaterial, dielectric resonator, transparent, and flexible/wearable antennas. The impact of slots, decoupling structures, and partial ground on bandwidth, isolation level, and impedance matching is reported [47]. A quad-band multi-polarized monopole antenna made up of a combination of T-and L-shaped stubs was studied with parasitic multistubs in Y-direction behind patch antenna.…”

The introduction of wireless communication devices has sparked interest in small-size antennas. Additionally, the demand for multiband frequency operating antennas with various patterns is felt to fulfil the requirements and problems of fifth-and sixth-generation (5G and 6G) communications. Aside from excellent radiation efficiency and antiinterference performance, factors such as a greater frequency band, lower size, and ease of installation are also required. Therefore, multiband functioning and antenna miniaturization are necessary [13].

“…For various frequency bands over the years, a number of techniques have been investigated to improve MIMO antenna isolation, but very few techniques have been investigated for the mmWave frequency band. Planar MIMO antennas operating in the mmWave spectrum can be classified based on their structural configuration, as slotted radiator, defected ground, and metasurface [ 47 ]. Waveguide represents another important classification.…”

This paper focuses on the topic of joint communication and radar sensing (JCRS) and its applications in the scope of upcoming sixth-generation (6G) technology. While the fifth-generation applications have reached the consumer market in the last few years, JCRS has been identified as one of the key technologies for next generation networks. The role of JCRS will vary, ranging from tasks such as radar coordination, context awareness for communication, enhanced security, increased availability, and improving the resilience and trustworthiness of future networks. In this work, the niche of JCRS technology in the future 6G ecosystem, as well as several potential applications, are discussed with a focus on RF hardware. The use of centimeter (cmWave) and millimeter (mmWave) frequency spectrums in the context of JCRS system implementation have been further elaborated. After presenting the near-term application scenarios, the circuit implementation perspectives are investigated in terms of radio frequency (RF) front-end architectures, antenna implementation, and phased arrays. Different communication and radar antenna options are compared, and the best candidates are identified. The packaging options are also presented. From circuit and system perspectives, link budget and self-interference cancellation (SIC) are highlighted. Furthermore, future directions including the next steps on the path to enabling JCRS technology are presented throughout this article. Prior works focused more on physical layers and network capabilities of JCRS systems, with less focus on hardware possibilities; to fill this gap, this article aims to contribute to this exciting research topic with a holistic review of RF hardware, highlighting the diversity of applications and the available technologies to tackle the near- and long-term needs of consumer applications.

“…Internet usage statistics of different countries [11]. The signal baud rate may transport more information due to mmWave's high carrier frequency, resulting in a higher rate of data (bits/sec/Hz) & reduced the time of buffering while producing high-quality films [12]. Cellular communication exploits frequency reuse through cell splitting and sectoring to expand network coverage due to the mmWave's limited range [13].…”

The increasing volumes of data generated by social networking, cloud computing, e-commerce, and online video broadcasting necessitate the implementation of higher data rates. As the current 4G network encounters congestion and potentially struggles to accommodate the substantial data demand, there is a growing interest in millimeter wave (mmWave) technology. The 30-300 GHz mmWave spectrum is characterized by its broad bandwidth and low latency; it is having many applications in communication domains, also includes 5G cellular. Despite its atmospheric attenuation and non-line-of-sight (NLOS) propagation, the majority of nations have begun to implement mmWave 5G in the band of 28/38 GHz as a result of its reduced path loss exponent, minimal signal spread, and decreased atmospheric attenuation. While the patch antenna (single-element) is a compact and easily transportable choice for mmWave applications, its radiation efficiency, gain, and bandwidth are all subpar. Array antennas have effectively addressed these limitations by exhibiting significant enhancements in bandwidth, gain, and radiation efficiency. It is still limited in the maximum data rates it can accommodate. The rate of data can be increased by a factor of one thousand using Multiple-Input-Multiple-Output (MIMO) technology, which is enabled by geographical diversity and multiplexing techniques. As a result, the comprehension of structures of MIMO antennas operating at mmWave is imperative for the continued enhancement of performance. In comparing the efficacy of these designs, bandwidth, isolation, efficiency, gain, and radiation pattern are considered. In this paper, the most recent planar MIMO antenna designs, which are categorized as defected ground structures, Slot/Patch/Stub, MIMO Antenna Array, Dielectric Resonator Antenna, and Meta-Surface/Metamaterial Structures, are described. This paper also addresses the effects that slots, partial ground, and decoupling structures have on levels of isolation, bandwidth, and impedance matching. A comprehensive analysis of the design considerations and subsequent advancements is also provided in this paper.
