Low-profile embedded ultra-wideband antennas for portable devices
Abstract
This paper addresses the need for low-profile, ultra-wideband (UWB) antenna designs, which are required for laptop and other portable devices. By slotting the vertical ground plane close to the radiator of the antenna and modifying the feeding structure, a low-profile antenna is capable of providing well-matched bandwidth and accepted gain over UWB band. The design is validated by measurement in terms of impedance bandwidth, radiation patterns and gain.
