Abstract

An internal mobile antenna covering multiband for LTE (746 - 806 MHz), GSM850 (824 - 894 MHz), GSM900 (880 - 960 MHz), PCS1900 (1850 - 1990 MHz), WiMAX (3.4 - 3.6 GHz) and WLAN (5.15 - 5.85 GHz) frequency bands is proposed. In order to satisfy the operation at WLAN frequency band, a metal branch is placed near the feeding point. It is shown that the operation at low frequency bands (LTE / GSM850 / GSM900) can be achieved by increasing the length of the ground. Considering the size of the commercial mobile phones, more practical design which exhibits the similar effect that can be attained by increasing the length of the ground is proposed. The antenna was fabricated and its measured results of return loss and radiation patterns at each frequency bands are presented. FR4 substrate with relative permittivity of 4.4 was used. The overall size of the proposed antenna is 40 Ã— 100 Ã— 5 mm³.
