Wideband Conformal Antennas and Arrays

摘要

The work done investigates some unexplored degrees of freedom in microstrip antenna design with the goal of developing a modified substrate configuration with improved bandwidth and maintained radiation characteristics. Results indicate that sectioned substrates can deliver increased impedance bandwidth. A closed-form circuit-based model is also developed to predict the performance of these new antenna structures. The modified substrate techniques developed here will be used along with loading and slot etching techniques studied previously to construct wideband planar antennas and arrays.
