“…In 2016, Zhang et al demonstrated the potential of LCP TSAs for THz applications [77], as shown in Figure 6b. With the emergence of 5G technologies, multi-band and UWB omni-directional antennas with good flexibility have gained great interest in recent years [78][79][80][81][82][83][84][85][86]. In 2018, Madhav et al developed a compact MIMO antenna for automotive communication, achieving low mutual coupling between antenna elements [82].…”

With the emergence of fifth-generation (5G) cellular networks, millimeter-wave (mmW) and terahertz (THz) frequencies have attracted ever-growing interest for advanced wireless applications. The traditional printed circuit board materials have become uncompetitive at such high frequencies due to their high dielectric loss and large water absorption rates. As a promising high-frequency alternative, liquid crystal polymers (LCPs) have been widely investigated for use in circuit devices, chip integration, and module packaging over the last decade due to their low loss tangent up to 1.8 THz and good hermeticity. The previous review articles have summarized the chemical properties of LCP films, flexible LCP antennas, and LCP-based antenna-in-package and system-in-package technologies for 5G applications, although these articles did not discuss synthetic LCP technologies. In addition to wireless applications, the attractive mechanical, chemical, and thermal properties of LCP films enable interesting applications in micro-electro-mechanical systems (MEMS), biomedical electronics, and microfluidics, which have not been summarized to date. Here, a comprehensive review of flexible LCP technologies covering electric circuits, antennas, integration and packaging technologies, front-end modules, MEMS, biomedical devices, and microfluidics from microwave to THz frequencies is presented for the first time, which gives a broad introduction for those outside or just entering the field and provides perspective and breadth for those who are well established in the field.

This paper proposes two flexible ultra-wideband (UWB) multiple-input multiple-output (MIMO) slot antennas with connected ground and high isolation. Two MIMO antennas consist of two parallel slot antenna elements with coplanar waveguide feeds and ground. The antennas are etched on the liquid crystal polymer substrate and have the consistent sizes of 30 Â 56 Â 0.1 mm 3 .The first UWB-MIMO antenna can cover 3-13 GHz. By adding a U-shaped slot on the first antenna, a second UWB-MIMO antenna with a notch-band is designed, which can work in 3.2-13 GHz and filter the wireless fidelity frequency band (5-6 GHz). High isolation better than 20 dB is obtained by adding fence-shaped branches. In addition, the performance of the flexible MIMO antenna is analyzed, including diversity performance parameters such as envelope correlation coefficient, diversity gain, gain, and total active reflection coefficient. The proposed UWB-MIMO antenna can be applied in internet of things and wireless body area network frequency bands.
