A new internal antenna structure using a Z‐type hexagonal ferrite is introduced for the DVB‐H reception in folder‐type mobile phones. The antenna element operates as a coupling element to excite the chassis as a radiator. Using a Z‐type hexagonal ferrite, the proposed antenna can be designed with a considerably low volume of 0.75 cm 3 and meets the requirements of antenna for the DVB‐H service. The high isolation over 15 dB between the DVB‐H band and the communication bands (GSM, DCS, and PCS) is obtained. © 2009 Wiley Periodicals, Inc.
