“…Redistribution Layer (RDL) methods, crucial for establishing a secure link between the chip and substrate, serve as the fundamental technology for three-dimensional (3D) integrated circuits (IC) aiming at achieving superior performance, extensive functionality, and increased density [1][2][3]. Nevertheless, the chip's performance is susceptible to degradation due to silicon substrate noise when transmitting high-frequency signals through the RDL [4,5].…”

In this paper, an effective structure RDL-GR is proposed to improve the electrical and reliability of the fan-out wafer package (FOWLP) with the addition of a graphene layer on the surface of the Redistribution Layer (RDL), including suppression and modulation of signal delay and crosstalk noise. A modified circuit model is formulated to evaluate the impact of RDL-GR on the transmission characteristics at high frequencies. Subsequently, the validity of the model is verified by utilizing the HFSS. Found on the circuit at high frequencies, the transmission characteristics of the RDL-GR compared to the traditional RDL structure (Tr-RDL) have better performance. At the same time, measurement by Vector Network Analyser (VNA) is carried out and results prove that the maximum error values of S11 and S21 are 1.81% and 1.47%, and make a strong case that S-parameters of RDL-GR for simulation using HFSS are reliable.

“…With the rapid rise of emerging wireless systems, higher requirements are put forward for high-speed data transmission. Compared with the sub-6 GHz band, the spectrum resources at millimetre-wave (mm-wave) bands are more abundant, which drives the research and development of low-cost wideband mmwave antennas [1,2]. Due to the effectiveness in mitigating multipath interference and fading, the circularly polarised (CP) antennas have aroused great interest in wireless communication systems [3,4].…”

A circularly polarised (CP) antenna with highly symmetrical radiation patterns and wide operating bandwidth is presented for millimetre-wave (mm-wave) applications. By loading four parasitic inverted-F components around a SIW-fed S-dipole antenna, better axial ratio (AR) performance and higher gain performance are realised. Furthermore, the proposed antenna can achieve highly symmetrical radiation patterns in different elevation planes within a wide operating band. This unique feature makes it advantageous to more uniform signal coverage. To verify the effectiveness of the antenna, a prototype is fabricated and measured. The experimental results validate that the antenna covers the impedance bandwidth of 49.1% (21.2-35 GHz) and the AR bandwidth of 51.3% (20-33.8 GHz). Besides, the antenna peak gain can reach 10.42 dBic at 28.5 GHz. More importantly, the antenna can radiate extremely symmetrical and uniform waves in different elevation planes within a wide operating band (21-29 GHz). Attributed to these merits, the presented antenna shows great potential in various mm-wave systems.
