“…Another approach is to use a more suitable substrate for the antenna design. Many techniques have been proposed [5]- [7] using different substrates to obtain antennas with high gain and bandwidth to meet the necessary characteristics for the exploitation of these frequencies. However, antennas are only part of the system and its integration should be carefully considered.…”

In this paper, a Bull's-Eye (BE) antenna with circular polarization (CP) based on ridge gap waveguide (RGW) technology is numerically and experimentally demonstrated. The structure is excited from the bottom with a standard WR-15 waveguide (V-band) coupled through a step transition to a ridge-line that ends in two orthogonal arms of different lengths to generate CP. Radiation is coupled to the top plate by a central diamond slot surrounded by the BE structure, which consists of four concentric periodic corrugations around the slot. Simulations and experimental results are in good agreement, with axial ratio below 1 dB at the operation frequency and peak gain of 18.4 dB. The antenna has righthanded CP (RHCP) with polarization discrimination of more than 30 dB.

“…Nowadays, more and more high-data transmission applications are emerging in daily life, such as high-definition television, autopilot, and augmented reality/virtual reality. − Therefore, typical millimeter-wave bands for short-range wireless communication have been put forward, such as the 45 GHz band (IEEE 802.11aj) and 60 GHz band (IEEE 802.11ad), , which are worldwide license-free, providing the foundation for high-speed wireless communication. , Millimeter-wave wireless communication usually requires the antennas to be miniaturized and of wide bandwidth and high gain. − In addition, with the environment in which antennas operate becoming more and more complex, the explosive growth of antennas and other electronics also puts forward higher requirements for conductive materials. In the past, traditional metal materials such as copper, aluminum, and gold were extensively used for the manufacture of electronic devices, which led to environmental issues due to the pollution from the electronic waste. , In the meantime, the existing millimeter-wave antennas are mostly copper-based, making it difficult to obtain them with corrosion resistance, lightweight, and environmental friendliness to face the increasingly complex and versatile application scenarios. − Therefore, it is urgent to explore new-generation materials for application in millimeter-wave short-range wireless communication (MSWC), which can ensure the good working performance of electronic devices while possessing excellent mechanical stability, chemical stability, and environmental benignancy.…”

Millimeter-wave and short-range wireless communication is an important part of the Internet of Things due to its advantages of high transmission speed and large data capacity. In this paper, two antenna arrays operating at typical millimeter-wave bands (45 and 60 GHz) based on graphene-assembled films (GAF) are proposed for short-range wireless communication application. The 45 GHz graphene-assembled film antenna array is in the form of a magnetoelectric dipole antenna with a strip slot coupling to achieve bidirectional radiation, which offers an operating bandwidth of 40–49.5 GHz with a realized gain of 11.8 dBi. The 60 GHz graphene-assembled film antenna utilizes a microstrip discontinuous radiation array to achieve radiation with an operating bandwidth of 59–64 GHz, reaching the peak realized gain of 14.92 dBi over the working frequency. Finally, we proposed an experimental validation to verify the transmission performance of both antenna arrays in an actual conference room. The results show that the signal drops slowly in the room with drop rates of 0.064 dB/cm (at 45 GHz) and 0.071 dB/cm (at 60 GHz), while it steeply dropped through the wall with the drop rates of 2.3 and 3.13 dB/cm, more than 35-fold difference in signal drop rates in the room and through the wall. It has been confirmed that the proposed antenna arrays can successfully realize fast indoor short-range wireless communication while also preventing signal leakage through walls, thereby enhancing the security of information. In summary, this is the first time that we have applied graphene-based materials to millimeter-wave and short-range wireless communications, revealing the significant potential of carbon-based materials in high-frequency communication systems.
