Broad angle broadband 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 use of...

| description | 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 use of directional beams, it is important to track the transmitting device to maintain link connectivity. Wide angle receivers can be used to receive them but determining source angle has been an ongoing challenge. This study proposes a novel approach to overcome these challenges, balancing improved directionality with reduced directional gain by enhancing a traditional Leaky Parallel Plate Waveguide (LPPW). The proposed device can accurately determine the receiving angle of a beam by analyzing unique features extracted from the spatially resolved output. Experimentation and simulations reveal that the device allows for a broader angle of acceptance and calculation of the received angle at 200 GHz. This device can also be used as broadband receiver and can be reconfigured to optimize in different frequency bands. |
