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.

A reconfigurable narrow‐frame coupled‐loop antenna capable of providing hepta‐band long term evolution/wireless wide area network (LTE/WWAN) for metal‐rimmed smartphone applications is proposed. The ground clearance of this proposed antenna is only 7 × 70 mm2 which is promising for narrow‐frame smartphone applications. Moreover, this proposed antenna can realise the miniaturisation by employing a positive intrinsic negative diode (PIN diode), which can provide two working states. When the PIN diode is OFF, it can provide coverage for GSM850/DCS/PCS/UMTS2100/LTE2300/2500 operations. When the PIN diode is ON, the obtained bands are GSM900/DCS/PCS/UMTS2100/LTE2300/2500. Hence, by combining these two working states, GSM850/900/DCS/PCS/UMTS2100/LTE2300/2500 operations are achieved. In addition, the feasibility of realising decoupled multi‐antennas is demonstrated and its performances are well‐suited for future smartphone applications. Detailed design considerations of the proposed antenna are described. Both experimental and simulated results are also presented and discussed.

“…However, the slot antenna has difficulty covering the low-frequency bands by a single resonance [4]. To overcome this problem, various researches using multi-resonance at the lower frequency band have been studied [5][6][7][8][9]. In these studies, multi-resonance characteristic was achieved by using capacitive coupling feed.…”

In this paper, a planar printed hybrid short/open-ended slot antenna with capacitive coupling feed strips is proposed for hepta-band mobile applications. The proposed antenna is comprised of a slotted ground plane on the top plane and two capacitive coupling feed strips with a chip inductor on the bottom plane. At the low frequency band, the short-ended long slot fed by strip 1 generates its halfwavelength resonance mode, whereas the T-shaped open ended slot fed by strip 2 generates its quarter-wavelength resonance mode for the high frequency band. The antenna provides a wide bandwidth covering GSM850/GSM900/DCS/PCS/UMTS/LTE2300/ LTE2500 operation bands. Moreover, the antenna occupies a small volume of 15 mm × 50 mm × 1 mm. The operating principle of the proposed antenna and the simulation/measurement results are presented and discussed.
