A multi-band antenna, which consists of a diversity antenna in the DCS/PCS/UMTS bands and a MIMO antenna in the LTE17/LTE4 bands, is proposed and designed for mobile handset applications. The proposed antenna consists of the meandered PIFAs with branch lines. The radiation efficiency of the proposed antenna is higher than 30% in the LTE17/LTE4 bands and higher than 40% in the DCS/PCS/UMTS bands. The...
A diversity antenna for a tri-band application is proposed and designed. The proposed diversity antenna consists of two wideband planar inverted-F antennas (PIFAs) and a suspended line between two PIFAs. The measured results show that the proposed antenna has a wide impedance bandwidth (37%) enough to serve a triple band (PCS, UMTS and WiMAX), a high radiation efficiency (> 50%), and a low correlation...
Design of a multiband internal antenna for mobile handset applications is presented. Two antenna elements are formed on top and bottom of the common substrate and connected by metallic pin. Resonant frequency of each element is almost independent. Matching the impedance with the slit, a wide bandwidth is achieved so that the operating frequency bands include GSM (880-960 MHz), GPS (1575 MHz), DCS...
