“…However, with a dual‐port integrated UWB/NB antenna system, it is difficult to achieve more than two to three NBs without adopting a reconfiguration mechanism. The reconfiguration mechanism in CR includes, among others: (1) coverage of 2.2–11 GHz sensing band and four communicating bands at 3.854, 4.619, 5.2, and 6.095 GHz 8 depending upon switching modes with geometrical size 40 × 70 × 1.6 mm 3 ; (2) 3–11 GHz for sensing and three separate bands 9 (3.25–3.7 GHz, 5.5–6.5 GHz, and 8–8.4 GHz) for communication with total size 65 × 40 × 6.5 mm 3 . Furthermore, to enhance the reliability and performance, the multi‐port (i.e., more than two ports) antenna system for CR is a topic of interest in recent years 10 .…”

This article discusses the design of a compact antenna system for spectrum interweaved cognitive radio (CR). The system consists of a sensing filtenna and three communicating antennas. The sensing ultra‐wideband (UWB) antenna is a coplanar‐waveguide (CPW)‐fed monopole (2.2–11 GHz). The narrowband communicating patch antennas are reconfigurable through a switching mechanism, operating in six different frequency bands (5.54, 6.12, 7.60, 8.25, 9.64, and 10.29 GHz). To block the Wi‐MAX and WLAN bands, the proposed design uses a meandering slot and a stepped U‐slot in the monopole. Analysis of communicating antennas using the theory of characteristic mode analysis indicates good radiation in the desired frequencies. Isolation among these antennas is better than −18 dB. A constant group delay and linear phase response indicate a good time‐domain performance of the proposed UWB antenna. Simulated results match closely with those from measurements on the prototype. The proposed antenna system can find applications in various sectors adopting CR like internet of things.

“…Even though multiport antenna designs have the advantage of achieving a wide operating frequency range, it requires a complex switching network to operate between different NB antenna elements. To overcome the limitation of multiport and complexity involved in switching, a dual port UWB Dielectric Resonator Antenna (DRA) is integrated with frequency reconfigurable NB antenna [13]. The designed The dual and multiport antenna system enables simultaneous sensing and communication over the channel.…”

In this paper, a compact, single port, multimode reconfigurable UWB-NB antenna with a novel feeding network is presented. The proposed antenna consists of a pentagonal-shaped monopole radiator, a beveled-shaped partial defected ground plane with a rectangular slot, and a reconfigurable bypass feeding network. The antenna realizes a wideband frequency range from 2.4 to 18 GHz and four narrow band frequency ranges, 5.3 to 6.8 GHz, 6.0 to 7.6 GHz, 7.2 to 8.8 GHz and 8.4 to 11.4 GHz. The antenna provides an omnidirectional radiation pattern with gain from 2.2 to 6.2 dBi maximum at 12 GHz and voltage standing wave ratio (VSWR) ranges from 1 to 2. The fabricated antenna has an overall dimension of 18×21×1.6 mm 3 . Sensing and tuning ranges of the fabricated antenna shows good agreement with the simulation results. The proposed antenna has an advantage of simple design, low profile, single port excitation and omnidirectional radiation pattern making it suitable for applications such as handheld mobile cognitive radio systems.

Two reconfigurable UWB antennas with band rejection characteristics are presented in this paper. By applying concept of parasitic element and etching slot in these two proposed antenna design WiMAX and WLAN band rejection are obtained, respectively to avoid potential electromagnetic interference (EMI). The proposed antennas are printed on 30mm x 40 mm Rogers5880 substrate. Furthermore, ideal switches are employed to achieve switchable band rejection UWB antenna.In this paper, two designs of reconfigurable UWB antenna with band rejection were proposed; namely a reconfigurable UWB antenna with WiMAX band rejection (Antenna 1), reconfigurable UWB antenna with WLAN band rejection (Antenna 2). The proposed antennas were successfully simulated, fabricated and measured. The Antenna 1 have impedance bandwidth from 2.99 GHz to 10.58 GHz with band rejection at 3.52GHz by utilizing C-shaped parasitic stripline. Meanwhile, Antenna 2 achieved an operating bandwidth from 2.99 – 10.82GHz with VSWR less than 2 except for the WLAN band operating at 4.92 – 5.84 GHz.The measured results for both antennas show good agreement with simulated ones.
