Abstract

Abstract:

The traditional mobile phone antenna has many disadvantages, such as complicated structure, high profile, large size. In order to reduce the size of a mobile phone antenna, a novel miniaturized mobile phone antenna with a hendeca-band is presented in this paper by studying the method of frequency band broadening of the miniaturized low profile dual layer microstrip antenna. The size of the presented antenna is only 37.0mm×7.2mm. First, by using the monopole and the ground strip coupling technologies to excite the resonant mode, the high-frequency bandwidth of the antenna is broadened. Then, the low-frequency bandwidth of the antenna is also broadened by using the loading inductance method to shift low-frequency resonance. The measured results have demonstrated that eight LTE/WWAN bands can be covered and that the S₁₁ of the proposed antenna is lower than -10dB in the range of GPS, WiFi and Bluetooth bands. Compared with traditional microstrip antennas, the proposed antenna has good radiation gain and efficiency as well as the small size, simple structure and wide frequency band.
