Ultra-miniature UHF antenna using magneto-dielectric material

A new way of designing an efficient and very small antenna is presented. The proposed antenna, with a size of λ 0 /41, combines meander lines and a magneto-dielectric material having high refractive index and relatively low losses. The antenna gain measured (more than -5-dBi) is sufficiently high for TV signal reception in the lowest UHF band around 470-MHz.
