Modular, Reconfigurable Block Cell Antenna Concept for Millimeter-wave 5G

A reconfigurable block cell antenna (BCA) concept is proposed for millimeter-wave (mmWave) 5G applications. The 4×4 BCA is exemplified using a low temperature co-fired ceramic (LTCC) process. All ports of the proposed BCA achieve a reflection coefficient below - 10 dB in 28.5 GHz. The proposed BCA features a maximum gain of 7.6 dBi and 15 different modes that can support multiple polarizations and a half of the spherical beamsteering angle.1

Optically Transparent Nano-Patterned Antennas: A Review and Future Directions

Transparent antennas have been continuously developed for integration with solar cells, vehicular communications, and ultra-high-speed communications such as 5G in recent years. A transparent antenna takes advantage of spatial extensibility more so than all other antennas in terms of wide range of usable area. In addition, the production price of transparent antennas is steadily decreasing due to the development of nano-process technology. This paper reviews published studies of transparent antennas classified by various materials in terms of optical transmittance and electrical, sheet resistance. The transparent electrodes for the transparent antenna are logically classified and the transparent antennas are described according to the characteristics of each electrode. Finally, the contributions transparent antennas can make toward next-generation 5G high-speed communication are discussed
