Compact internal antenna using a ferrite material for DVB-H reception in mobile phones

A compact internal antenna with a partially filled ferrite substrate for DVB-H (Digital Video Broadcast for Handheld) reception in a mobile phone is proposed. Ferrite substrate whose relative permittivity (ε
r
) and permeability (μ
r
) are 7 and 18, respectively, is used to effectively reduce the antenna size. Measured results show that the proposed antenna can work well for DVB-H applications.
