Abstract :
A small-size low-profile narrow-frame antenna for seven-band WWAN/LTE operations in the internal smartphone applications is proposed. The greatest highlight of this proposed antenna is that its narrow edge has a width of only 5 mm, which is very novel for smartphone applications. Meanwhile, the proposed narrow-frame antenna has a small size of 5 × 40 mm2 and a low profile of 3 mm above the circuit board, which makes it very promising for slim smartphone applications. The proposed antenna is capable of covering GSM850/900/DCS/PCS/UMTS 2100/LTE2300/2500 operating bands. Detailed design considerations of the proposed antenna are described, and both experimental and simulation results are also presented and discussed.
