Abstract

A four-element infrared leaky-wave antenna coupled bolometer was investigated with the goal of characterizing signal extraction as a long wave infrared (LWIR) detector. Simulations were carried out using Ansys HFSS. Various simple loading techniques were seen and their behavior characterized. A transmission line loaded antenna coupled bolometer was investigated using an incident-wave excitation and angle of sensing inaccuracies were observed. A position pertaining to the design criterion of angular scanning in frequency was then parametrically tuned for. The leaky-wave antenna was then simulated in the transmitting scenario. A waveport fed case was explored and far-field pattern generated. Transmission line losses leading to inaccuracies in angle sensing were investigated for the transmitting case. Improvement in directivity was observed for larger number of patch elements in the leak-wave antenna array.
