Optically Transparent Microstrip Feed Lens Antenna for 6G Wireless Backhaul Communication

The demand for high-data-rate communication services in 5G and 6G wireless communication systems has led to an increasing need for mounting multiple access points and base stations. However, the proliferation of these infrastructure elements can result in a cluttered and visually unappealing environment. To address this issue, optically transparent antennas (OTAs) offer an ideal solution by maintaining device aesthetics while fulfilling coverage and bandwidth requirements. In this work, initially link budget analysis for deployment of wireless backhaul communication system with target data rate of 100 Gbps. Then, we have designed microstrip fed with lens antenna for operating the frequency of 300GHz.These antennas were designed and simulated using the High Frequency Structure Simulator (HFSS) with transparent quartz glass as the substrate and graphene as the patch material. To obtain a high-directional beam, a hollow hemispherical lens made of lead sil-icate was used. By using a lens, the gain is increased by about 50%, i.e., 9.63 dB, when compared to the normal antenna gain of 6.13 dB.
