“…To explain, the majority of reported flexible and wearable patch antennas resonate at a single-mode transverse magnetic (TM) mode, which is typically the first-order TM 10 mode [23]. Nevertheless, to excite multiple modes simultaneously, a complex antenna structure is often needed [23], [24]. The dimensions of a rectangular microstrip patch antenna can be calculated analytically for a given TM resonant mode based on the length and width [25].…”

“…Compared to the multi-mode patch in [24], the proposed antenna compares favorably when the antenna efficiency is normalized to the thickness, despite being implemented on textiles and not RF laminates. In addition, the wider bandwidth in [24] was achieved using a Substrate-Integrated Waveguide (SIW) cavity and a very thick (0.11λ 0 ) substrate. While broadband "wire-type" antennas such as [37] achieve higher efficiency and bandwidth on low-loss substrates, the antenna requires double-sided etching and the efficiency is only achiev- able with tanδ<0.001 substrates.…”

Owing to the shorter wavelength in the millimeter-wave (mmWave) spectrum, miniaturized antennas can receive power with a higher efficiency than UHF bands, promising sustainable mmWave-powered Internet of Things (IoT) devices. Nevertheless, the performance of a mmWave power receiver has not been compared, numerically or experimentally, to its sub-6 GHz counterpart. In this paper, the performance of mmWave-powered receivers is evaluated based on a novel wearable textile-based higher-order mode microstrip antenna, showing the benefits of wireless power transmission (WPT). Firstly, a broadband antenna is proposed maintaining a stable wearable measured bandwidth from 24.9 to 31.1 GHz, over three-fold improvement compared to a conventional patch. The proposed antenna has a measured 8.2 dBi co-polarized gain with the highest thickness-normalized efficiency of a wearable antenna. When evaluated for compact power receivers, the measured path gain shows that WPT at 26 GHz outperforms 2.4 GHz by 11 dB. A rectenna array based on the proposed antenna is then evaluated analytically showing the potential for up to 6.3x higher power reception compared to a UHF patch, based on the proposed antenna's gain and an empirical path-loss model. Both use cases demonstrate that mmWave-powered rectennas are suitable for area-constrained and large-area wearable IoT applications.

“…Further in frequency reconfigurable designs using slots [15,16], detailed theory about antenna functioning by highlighting the effects of Uslot along with diodes is not put forward. A similar study lacks in modified E-shape design as reported in [17]. In comparison, the present paper puts forward detailed theory about antenna functioning in terms of patch modes as well as proposes design methodology using resonant length formulations.…”

Wideband designs of nearly square microstrip antenna using two half U-slots and rectangular slots are proposed. The slots optimize the spacing in between the patch modified TM 11 , TM 20 , TM 02 , and TM 30 resonant modes to yield wideband response. The design with two half U-slots yields bandwidth of around 1000 MHz (∼ 50%) whereas that with an additional rectangular slot yields bandwidth of 1345 MHz (∼ 61%). Due to the presence of higher order modes, the proposed design offers higher cross polar radiation pattern across the entire bandwidth with the gain greater than 5 dBi. The formulations for the modified patch modes and subsequent redesign procedure are presented, which serve as a guideline in the designing of similar antennas around specific resonance frequency. With the given antenna characteristics, the proposed antennas will find applications in personal and mobile communication systems.

The intensive research in the fifth generation (5G) technology is a clear indication of technological revolution to meet the ever-increasing demand and needs for high speed communication as well as Internet of Thing (IoT) based applications. The timely upgradation in 5G technology standards is released by third generation partnership project (3GPP) which enables the researchers to refine the research objectives and contribute towards the development. The 5G technology will be supported by not only smartphones but also different IoT devices to provide different services like smart building, smart city, and many more which will require a 5G antenna with low latency, low path loss, and stable radiation pattern. This paper provides a comprehensive study of different antenna designs considering various 5G antenna design aspects like compactness, efficiency, isolation, etc. This review paper elaborates the state-of-the-art research on the different types of antennas with their performance enhancement techniques for 5G technology in recent years. Also, this paper precisely covers 5G specifications and categorization of antennas followed by a comparative analysis of different antenna designs. Till now, many 5G antenna designs have been proposed by the different researchers, but an exhaustive review of different types of 5G antenna with their performance enhancement method is not yet done. So, in this paper, we have attempted to explore the different types of 5G antenna designs, their performance enhancement techniques, comparison, and future breakthroughs in a holistic way.
