A compact, circular UWB fractal antenna with triple reconfigurable notch rejection bands is
proposed. It rejects the crowded frequency bands WiMAX, WLAN and X band interferences …

ABSTRACT A low profile and compact size cognitive radio (CR) sensing/communicating
antenna system is presented in this paper. A slotted elliptical monopole antenna is proposed …

The rapid development of ultrawideband (UWB) communication systems has resulted in
increasing performance requirements for the antenna system. In addition to a wide …

A compact ultra-wideband (UWB) monopole antenna with reconfigurable band-notch
characteristics is demonstrated in this paper. It is comprised of a modified rectangular patch …

In this article, a small‐printed Bluetooth/LTE/UWB/X‐band/Ku‐band monopole antenna with
high rejection triple band‐notch is presented. Notched bands include WiMAX (IEEE802. 16 …

This paper presents a compact wide-slot ultrawide-band (UWB) antenna with reconfigurable
and sharp dual-band notches compatible with the underlay cognitive radio systems. The …

A compact ultrawideband (UWB) antenna with reconfigurable triple band notch
characteristics is proposed in this paper. The antenna consists of a coplanar waveguide-fed …

In this paper a multifunctional antenna is presented which offers an ultra-wideband (UWB)
operation, an UWB operation with two switchable notches and reconfigurable dual-band …

To meet the requirements of miniaturization, multi-functions, and anti-interference of the
antenna, this paper proposes a compact dual notch band frequency reconfigurable ultra …

In this paper, a CPW feed ultrawideband (UWB) slot antenna with a single reconfigurable
notched band is proposed for overlay cognitive radio (CR) systems. The proposed antenna …
