Compact controlled reception pattern antenna for interference mitigation tasks of global navigation satellite system receivers

In this study, a novel compact controlled reception pattern antenna for global navigation satellite system (GNSS) applications is presented. Details of the design and the fabrication are given together with measurement results. The miniaturisation has been achieved by employing a five-element polarimetric array approach, resulting in anti-jamming capabilities for many applications where the antenna size is a major constraint. The antenna has a relatively wide bandwidth around the GNSS L1 band which contains many different GNSS signals. The anti-jamming performance of the antenna with respect to differently polarised jammers as well as its positioning capability are investigated.
