The article is discussing the final design of a VHF communication antenna integrated in a composite winglet of the EV-55 small transport aircraft. The antenna is designed to operate in the VHF band reserved for civil aviation, 117.975 – 137 MHz with optimal VSWR below 2.5. Compared with a standard vertically polarized monopole antenna, the radiation pattern in the horizontal plane shall not be down more than 6 dB and vary more than 6 dB [2].

The article is devoted to highlight the challenges, bottlenecks and possible
solutions of VHF antenna integrated into a winglet from both the designer‘s and the
airframer‘s perspective. We look into pros and cons specific for different antenna solutions
and discuss ways how to protect them against possible electromagnetic environmental effects.
As an outlook, a winglet with integrated VHF notch antenna designed within the ACASIAS
project will be described in better detail.
