According to the demands of modern communication products, Laptop/Tablet, at least four antennas are required to provide 3G WCDMA, 4G LTE, WiFi, BT, GPS, and Wimax. Recently, most antennas have employed planar inverted-F antenna (PIFA) design. However, the conventional PIFA suffers from narrow bandwidth and the relative isolation is another issue when high efficiency of antennas is demanded. If we can use one antenna to cover above-mentioned frequency bands, the antenna can economize space in comparison to that of using the four antennas. The proposed antenna is composed of a broadband monopole and three parasitic antennas. It can cover 824-960 MHz, 1575 MHz, 1710-2690 MHz, 3300-3800 MHz, and 5150-6000MHz. Besides, the proposed antenna is suitable to be placed at the top or side of the Laptop/Tablet monitor due to its dimensions of 60 (length) × 3 (width) × 12 (height) mm3.
