Abstract (en)
[origin: WO2008092592A1] An antenna apparatus (100) for transmitting and receiving electromagnetic signals. The antenna apparatus (100) comprises a ground plane (110) and an antenna element (120), which is arranged at an antenna-element spacing (150) above the ground plane (110). In addition, the antenna apparatus (100) comprises a plurality of parasitic elements (130), which are arranged on the ground plane (110) radially symmetrically around the antenna element (120), wherein the parasitic elements (130) are electrically connected to the ground plane (110).
