Broad Angle Resolver for THz Band

Abstract: Terahertz (THz) communication systems hold immense potential for high-speed data transfer across various domains yet face challenges due to directionality constraints because of free space path loss. To address this, directional beams are commonly employed in THz technology. With the usage directional beams, it is important to track the transmitting device to keep the link connectivity. Leaky Parallel Plate Waveguides (LPPWs) were introduced to tackle this challenge. But traditional LPPW uses unique angle-frequency relationship which requires broad range of frequencies. This study proposes a novel approach to mitigate these constraints, balancing directionality with reduced directional gain to enhance LPPW adaptability. The proposed device can accurately determine the receiving angle of a beam by analyzing unique features extracted from the dual peak outputs. Experimentation and simulations reveal that the device allows for a broader angle of acceptance and calculation of the received angle.
