title = "Design of a Transceiver Integrated Multiple-Beam Cassegrain Antenna at 340GHz for Situational Awareness",
abstract = "This letter proposes a transceiver integrated multiple-Beam Cassegrain Antenna at 340GHz. The proposed receiving antenna uses a sixteen-channel receiving feed array. Sixteen receiving feeds are misaligned to produce offset beams, and each of them is received individually, which simplifies the structure and provides flexibility for signal processing. The proposed transmitting antenna and receiving antenna are coaxial. The main reflector of the parabolic transmitting antenna is connected with the receiving antenna{\textquoteright}s sub reflector, thereby improving the space utilization and the robustness. Sixteen-beam Antenna ensures a large-angle scanning, and works stably within a bandwidth of 25GHz. The main lobe gain is greater than 55dB, 3dB beam-width varies around 0.16。 and the sidelobe levels are lower than -24dB for all the beams. The proposed antenna shows an excellent radiation performance which can meet the needs of RF front-end of the situational awareness system.",
