A compact broadband omnidirectional vertically polarized VHF antenna for aircraft

A very efficient miniaturized VHF antenna with dimensions of 0.15λ 0 × 0.15λ 0 etched on 0.787 mm and ε r =4.4 dielectric FR-4 substrate is presented. It is inspired from the Sarabandi and co-authors works. The antenna is vertically polarized and behaves like a vertical dipole antenna used for Civil...

Description
Summary:A very efficient miniaturized VHF antenna with dimensions of 0.15λ 0 × 0.15λ 0 etched on 0.787 mm and ε r =4.4 dielectric FR-4 substrate is presented. It is inspired from the Sarabandi and co-authors works. The antenna is vertically polarized and behaves like a vertical dipole antenna used for Civil Aviation. It is composed by a great number of folded slots arranged in circular loop geometry and has a total length of a half-wave. The numerical simulations show a resonance frequency in the desired VHF frequency range. Using inductive and capacitive loading (LC circuit) impedance, the bandwidth can be significantly increased. All results are to be achieved with CST simulator.Proceedings
