摘要: A surface-mount chip antenna integrated with the speaker in the mobile phone for GSM/DCS/PCS/UMTS multiband operation is presented. The antenna is to be mounted on the top no-ground portion of the system circuit board of the mobile phone as an internal multiband antenna, and the speaker in the mobile phone can be inset into the chip base of the antenna to achieve a compact integration of the antenna and the speaker. Moreover, the chip antenna occupies a small volume of 35.5 � 10 � 7 mm3 (about 2.5 cm3) only. Details of the proposed chip antenna are presented.
