UWB Antenna with Stop-band Notch and Remm Nulls

摘要

In this paper,a narrowed band-stop UWB antenna is presented,it satisfies FCC's handhold/indoor standards and avoids occupying the frequency range which WLAN 802.11a stays. The bandwidths of stop band and transition band are now controllable by inserting return nulls,the peak of the VSWR is over 8.17,while the VSWRInthe pass-band is kept lower than 2. The contribution of each stub is analyzed.
