Abstract
The present invention relates to the field of microwave antenna and particularly to transmitting and receiving planar antenna design having an omni-directional radiation pattern for ultra wideband (UWB) applications. The object is to provide a planar antenna design for UWB system which is capable of transmitting/receiving microwave signals within the UWB frequency band, capable of a simple planar feeding and a printed low-cost manufacturing antenna, achieves a significant cost reduction by simultaneously applying antenna layout prints while manufacturing classical radio frequency (RF) front-end chip circuits and capable to cope with symmetrical omni-directional transmitting/receiving signals. It is solved by an antenna apparatus for a wireless electronic equipment operable to transmit and/or receive electromagnetic waves in ultra wideband technology comprising at least one radiator device operable to transmit and/or receive an electromagnetic wave, a ground plane device operable to reflect an electromagnetic wave transmitted and/or received by the radiator device and a feeding device) operable to supply signals from and/or to the radiator device, characterised in that the radiator device and the ground plane device are arranged along a common symmetry axis and are planar on the same plane, whereby the radiator device tapers towards the ground plane device.
