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 λ0/41, 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.
