Compact Wideband Balanced Antenna Structure for 3G Mobile Handsetsctures of balanced type of antenna radiators have been introduced. Comparing to the unbalanced antennas, their low levels of induced current on the ground plane, stable radiation performance, and relatively low specific absorption rate (SAR) beside to human head have been observed with balanced ante

Double-Monopole Crescent-Shaped Antennas with High Isolation for WLAN and WIMAX Applicationsantenna are proposed where one antenna is intended for WLAN and the other for WIMAX applications. Each antenna has the form of a crescent-shaped monopole. The lengths of the two radiating arcs are chosen for resonance at 2.45 GHz and 3.5 GHz to comply with the WLAN and WiMAX standards, respectively.

Miniaturized Monopole Wideband Antenna with Tunable Notch for WLAN/WiMAX Applications inner crescent shape along with an outer shape over the surface of the substrate. By placing a small capacitor (varactor) between the inner and outer arches, the center frequency of each notch can be individually shifted downward. The antenna exhibits a wide impedance bandwidth from 1.5 to 5 GHz wi

Miniature EBG Two U-Shaped Slot PIFA MIMO Antennas for WLAN Applications the substrate in such a way that surface waves are completely forbidden from forming, resulting in antenna efficiency and bandwidth improvements, while reducing the side lobes and electromagnetic interference levels. EBG is also used to improve the isolation and diversity gain in MIMO systems. EBG
