“…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.

“…In Table 1 are presented the dimensions of the antenna developed in this paper against the antennas from the literature, their resonance frequencies and the values of the realized gains. A similar antenna design is proposed in [14]. Compared to [14], the antenna suggested in this paper is optimized to operate at the cellular and C-V2X frequencies while mounted on a plastic piece under the Rogers 3850 substrate.…”

This paper highlights the impact of the ground, of the vehicle surroundings and of the car body on signal transmission and reception of a dual-band microwave antenna tested on two automotive plastic parts on a convertible vehicle for cellular and Cellular -Vehicle To Everything (C-V2X) communications. The implemented antenna operates at 975 MHz and 5.5 GHz and facilitates the future vehicular communications in vehicles without steady rooftops. Four experiments are performed with the antenna placed (a) in the Satimo near field system; (b) on a stanchion at an outdoor range facility without the presence of a car; (c) at the outdoor facility in the side mirror of the convertible vehicle; and (d) on the trunk lid of the same vehicle. Antenna co-and cross-polarization radiation patterns are measured and results indicate that the ground and the vehicle's body affect the radiation performance of the antenna. The presence of ground causes an increase in the antenna's cross-polarization level. The reflections caused by the car's body perturb the omni-directional radiation pattern of the antenna and may degrade the vehicular microwave signal transmission due to the presence of nulls.
