Abstract :
In this paper, a multi-band internal antenna for WiBro/WLAN/M-WiMAX (2.3 GHz ~ 2.69 GHz) and WCDMA services is proposed. The proposed antenna is composed of a MIMO antenna with two identical folded monopoles for WiBro/WLAN/M-WiMAX services and a separate folded monopole antenna for WCDMA service. For the MIMO antenna, two stubs are added between the two elements to improve the isolation performance. The antenna has the high radiation efficiency of greater than 60% and the isolation between the two feeding ports of MIMO elements is higher than 20 dB in the frequency band of 2.3 GHz ~ 2.69 GHz.
