Surface‐mount chip antenna with a thin thickness of 3 mm and a small volume of 3 × 4 × 50 mm3 (0.6 cm3) for eight‐band long term evolution/wireless wide area network (LTE/WWAN) operation in the slim mobile phone is presented.The antenna is a simple two‐strip shorted monopole, yet it can provide two wide operating bands of at least 698–960/1710–2690 MHz to cover the three LTE bands (LTE700/2300/2500) and five WWAN bands (GSM850/900/1800/1900/UMTS). The antenna is suitable to be mounted on the no‐ground board space of the system circuit board of the mobile phone. Wideband operation is achieved by incorporating an on‐board feeding structure formed by a short shorting strip and a chip capacitor–loaded feeding strip, both are of 8 mm in length and disposed on the no‐ground board space, to the proposed chip antenna. Details of the antenna including the on‐board feeding structure are presented.
