Abstract: The present disclosure relates to a switching antenna for automotive Ultra-Wide-Band (UWB) communication. The switching antenna includes a substrate section, a radiating section having a plurality of radiators formed on the substrate section so as to be spaced apart from each other to provide a pattern signal, and a selective signaling section formed on the substrate section to selectively connect the radiating section to cause a radiation pattern of the radiating section to be one of directional and omnidirectional.

Abstract: Proposed is a switching antenna for vehicular UWB communication, the switching antenna including a substrate, a directional radiation unit formed on the substrate and configured to provide a directional radiation signal, a non-directional radiation unit formed on the substrate and configured to provide a non-directional radiation signal, and a signal providing unit formed on the substrate and configured to provide an on or off signal to either the directional radiation unit or the non-directional radiation unit.

Abstract: The present disclosure relates to a switching antenna for UWB communication for a vehicle. The switching antenna may include a substrate part, a radiation part formed in the substrate part and configured to radiate an omnidirectional pattern signal, a main ground part formed in the substrate part and disposed below the radiation part, side ground parts formed on the substrate part and disposed on both sides of the radiation part, and a selection signal part formed in the substrate part and configured to induce a radiation pattern of the radiation part to become either directional or omnidirectional by selectively connecting the main ground part and the side ground part.
