This paper presents an Ultra-Wideband (UWB) patch antenna which is aimed to be an Anchor-antenna in UWB localization systems. It can operate distinctively in two different UWB frequency channels. Both of these channels have 500 MHz bandwidth, the lowband channel is centered at 4 GHz and the highband channel at 6.49 GHz. Reconfigurability to switch from one channel to another is achieved by changing the size of the radiating element. Additionally, this UWB antenna is aimed to be circularly polarized over both channels, which is realized through two branchline couplers placed on a bottom layer. Results of reconfigurability and circular polarization operation are verified by simulation and measurements.

Abstract
This paper presents an Ultra-Wideband (UWB) patch antenna which is aimed to be an Anchor-antenna in UWB localization systems. It can operate distinctively in two different UWB frequency channels. Both of these channels have 500 MHz bandwidth, the lowband channel is centered at 4 GHz and the highband channel at 6.49 GHz. Reconfigurability to switch from one channel to another is achieved by changing the size of the radiating element. Additionally, this UWB antenna is aimed to be circularly polarized over both channels, which is realized through two branchline couplers placed on a bottom layer. Results of reconfigurability and circular polarization operation are verified by simulation and measurements.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione
