“…The relative positioning of an antenna in vehicles, aircraft, or vessels for tactical applications is a complex task [1], [2], as highlighted by several factors in [3]- [7]. The mutual coupling between the antenna and the conducting elements in the vicinity, the finite and irregular dimensions of the ground plane [8], aspects of electromagnetic compatibility [9], [10], among others, are some examples of these critical issues.…”

For vehicle tactical radio communications, positioning antennas along the structure is a complex task. In vessels, there are several radio systems installed operating from HF to SHF. Consequently, the antennas need to share the same restricted space while preserving electromagnetic compatibility. In this context, this work presents a parametric analysis of the positioning of HF monopole antennas on the upper bridge of a typical Navy frigate. A numerical antenna analysis tool was chosen to support the intended analysis. Six positioning scenarios were simulated, evaluating the performance change of figures of merit such as the reflection coefficient and gain, due to the mutual coupling between the antennas and the main metallic objects within their close range. Furthermore, from the analysis, it was possible to establish recommended distances of decorrelation between the antenna and the main nearby objects.
