Low-profile broadband dual-mode four-arm slot spiral The authors propose a low profile 4-arm slot spiral for broadband commercial applications. The antenna is designed for circularly polarised dual-mode, 1st (normal) mode and 2nd (split-beam) mode, operation from 1.4–3.5 GHz and 2.5–6 GHz, respectively. Phase progressions at arm ports are realised through the odd and even coplanar waveguide (CPW) excitations, a dual Dyson balun, and a single A slot spiral in carbon-fibre composite laminate as a Conformal load-bearing antenna structures, which afford load-bearing structures with radar capability, are a promising technology to reduce weight and drag of air vehicles. This article presents an investigation of the mechanical and electromagnetic performance of slot log-spiral antenna in carbon-fibre composite structures. Compared with traditional rectangular slots, equiangular slot spiral A SPIRAL SHAPED SLOT AS A BROAD-BAND SLOT- TED … slot spiral antenna to explain its broad-band characteristics. The total electrical e–ciency and peak realized gain of this slot were compared with those of a rectangular slot which is the current slot shape used in SWASS. The gain patterns from an optimised spiral shape slot were simulated and conflrmed by measurement. 2.
