This article presents a nine‐band antenna whose size is 70 mm × 7 mm × 5.8 mm for 4G/5G smartphones. The proposed antenna consists of a T‐shape coupled line and two ground branches. The T‐shape coupled line is used to produce the resonances at about 925 and 2900 MHz respectively. One ground branch along with the T‐shape coupled line is used to cover the lower band (698‐960 MHz), and the other ground branch is used to cover the 3.6 GHz band (3400‐3800 MHz). By using the higher order modes of the T‐shape coupled line and the ground branches, the higher band (1710‐2690 MHz) is covered. The advantage of the proposed antenna is that a nine‐band antenna can be realized with an only 7 mm ground clearance and without using any lumped element. A prototype is manufactured and measured. According to the measured results, at the bands of 0.693‐0.98 GHz, 1.69‐2.94 GHz, and 3.05‐4 GHz, the S11 are smaller than −6 dB. The −6 dB impedance operating frequency band of the proposed antenna can cover the LTE700, GSM850, GSM900, DCS, PCS, UMTS, LTE2300, LTE2500, and 3.6 GHz bands. The simulated and measured results of the radiation performance also are presented.

A novel technique to design a mobile phone antenna by using an ultrawideband (UWB) antenna configuration is proposed. The technique is validated with a novel printed slot antenna configuration. The slot is composed of a circle connected to a trapezoid and fed by means of a 50 Ω microstrip line connected to a patch with similar shape to the slot. An UWB antenna with size of 19 mm × 24 mm and measured −10 dB bandwidth of 2.97‐11.32 GHz is developed based on the configuration. When the configuration is applied in a system circuit board of 60 mm × 115 mm to design a mobile phone antenna, the simulated −6 dB bandwidths are 1.0‐1.2 GHz and 2.25‐15 GHz. To enhance antenna bandwidth, another slot with rectangular shape is etched in the ground plane, and the microstrip line is moved to the center of the circuit board and folded to distribute along the rectangular slot. The measured −6 dB bandwidths of the mobile phone antenna are 0.69‐1.09, 1.68‐2.75, 3.45‐3.52, and 3.62‐15 GHz.

“…These new standards often require a dual‐band or multiband system and the current built‐in mobile phone antenna generally also requires the coverage of GSM/DCS/Universal Mobile Telecommunications System. With the development of 4G communication technology, LTE/WLAN/WiMAX band coverage has become a new demand …”

A novel multifrequency mobile phone antenna with circularly polarized Global Position System (GPS) application is presented in this research. The antenna is composed of a gradient T‐type feedline and a ring‐metal patch with 4 different branches. Specifically, T‐shaped feedline and the ring‐metal patch are contributed to resonate in 1300 MHz‐1900 MHz. Meanwhile, the phase difference generated by the four branches of varying lengths, the antenna produces circular polarization at 1575 MHz. The etching slot in the patch can make the antenna work in 2400 MHz–2700 MHz. The experimental results verify the simulations. The designed antenna can be covered in Global System for Mobile Communications/Digital Communication System/GPS/Long Term Evolution/Wireless Local Area Network/Worldwide Interoperability for Microwave Access and other system operating frequency bands, which is suitable for the current multisystem mobile phone.
