Abstract :
This paper introduces a new ultra-wideband (UWB) printed circular dipole antenna having a filtering feature for rejecting the Wi-Fi band (4.9-5.9 GHz). UWB regulation in Europe [1] and Japan require the rejection or the avoidance of the 5 GHz Wi-Fi frequency band, but due to the very wide frequency band used by UWB technology, it is also particularly exposed to other systems disturbances. Some experiments revealed problems of coexistence between UWB and the local wireless networks working in the WLAN bands [2]. The proposed paper describes a Wi-Fi band rejection filter included in a previously developed compact UWB antenna [3]. Constraints such as the size and the cost of the antenna are taken into account in the design. Efficiency measurements of the realized filtering small antenna, using Schantzpsilas method, are in conformance with simulations.
