An internal PIFA/slot antenna for quad-band mobile handset applications is presented. The quad-band operation for the bar-type mobile handset is obtained by the resonant modes of the slot antenna in conjunction with those of the PIFA. The proposed antenna has a compact size of 42 times 10 times 4 mm3. The quad-band operation includes GSM850 (824-894 MHz), GSM900 (880-960 MHz), DCS1800 (1710-1880 MHz),...
A multi-band internal antenna including the DVB-H (digital video broadcast for handheld terminals) band is proposed for clamshell types of the mobile handsets. It consists of two radiating elements: a PIFA is for the GSM band, and a monopole covers DVB-H, GPS, DCS, and PCS bands. The measured results show that the proposed antenna has enough isolation between two elements and effectively covers all...
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...
