A varactor diode reconfigurable ultra‐wideband antenna that with electrically controlling the rejects on‐demand WiMAX, WLAN, and C‐BAND signals in the entire 3.1–10.3 GHz range is presented. The antenna design, embedding the active devices, integration with the varactor diode, and biasing network are described. A method to vary the rejection on‐demanded bandwidth is also provided. The fabrication prototype is conformal and double‐sided. Results indicate a successful integration and minimal interference of the varactor diode voltage and biasing circuitry with the antenna, paving the road for more integrated reconfigurable antenna on communication systems using active devices technology. © 2015 Wiley Periodicals, Inc.

“…Additionally, the knowledge on beam-steering effects by the use of different RF PIN and practical solution to improve DC biasing circuitry system is very limited and leave unexplored [4,5,10]. However, in this research, the combination of embedded RF PIN diode with DC biasing circuitry at the ground plane has solved those affects and any unnecessary spurious effect that could be generated from the DC biasing wires.…”

“…However, recent works on reconfigurable antennas have provided an alternative solution to perform the beam steering with less complexity. Such reconfigurable antenna adopts the use of active component like PIN diodes [4][5][6][7], varactor diodes [8] and MEMS [9] to control the beam steering/pattern of the antenna. These devices provide switching mechanisms where the current paths and resonant length are altered to offer beam-reconfigurability.…”

Abstract-In this paper, an electronically reconfigurable beam steering antenna using embedded RF PIN switches based parasitic array (ERPPA) is proposed for modern wireless communication systems that operate at 5.8 GHz frequency. In the proposed antenna, a single driven element is fed by a coaxial probe, while each of the two parasitic elements is integrated with an RF PIN switches that embedded inside the substrate. In the conventional reconfigurable antennas, the RF PIN switches are mounted on narrow slots created on the top or bottom layer of the radiator/parasitic elements, which could lead to the dimensional changes of the antenna and degrade the performance in terms of beam steering and return loss. However, this research proposes an exclusive solution where the RF PIN diodes at parasitic elements are embedded inside the substrate thus no additional slots have to be created to mount the SMCs on the antenna. In this regard, the proposed antenna is highly competent to eliminate the intermodulation effect generated by the RF PIN diodes and the other passive elements associated with the PIN diodes. In this research, extensive investigations revealed that the parasitic element dimension and the selection of RF PIN switches significantly influence • are achieved in the xz -plane with measured peak gains at θ = −30 • , 0 • and +30 • are 6.5 dBi, 6.5 dBi and 4.9 dBi, respectively. The fabricated antenna with Taconic substrate provides a good agreement with the simulation result. Furthermore, the performance of ERPPA is further tested by outdoor measurement using a wireless bridging system to verify the functionality of the designed antenna at the angles of −45• . The analysis with the switched diversity combining scheme has demonstrated that a maximum diversity gain approximately of 12 dBi is offered by the proposed antenna. With a compact dimension of 32 mm by 76 mm, the proposed antenna is a potential candidate in point-to-point wireless applications such as WIFI application.

Abstract-In this paper, frequency reconfigurable slot-patch antenna with reflector at the back of an antenna is presented. The proposed antenna consists of a microstrip patch antenna and a microstrip slot antenna where the slot antenna is positioned at the ground plane underneath the patch. Three switches are placed in the slot. The antenna is capable to reconfigure up to six different frequency bands from 1.7 GHz to 3.5 GHz. The microstrip patch antenna produces three different frequency bands with directional radiation pattern while the microstrip slot antenna produces another three frequency bands with bidirectional radiation pattern. Due to the reflector placed at the back of the antenna, the radiation pattern is directional at all frequency bands. Simulated and measured results are used to demonstrate the performance of the antenna. The simulated and measured reflection coefficients and radiation patterns are presented and compared.
