“…Therefore, another RF PIN diode known as HPND-4005 is chosen for analysis. This diode is well known for its extremely low capacitance for its OFF state and can support frequency up to 18 GHz, small in size and provides high isolation loss at OFF state [17]. According to the technical data sheet provided by the manufacturer, the HPND-4005 PIN diodes are simulated as 4.6-Ω resistor and 0.017-pF capacitor in the ON and OFF states respectively [18].…”

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.

“…Furthermore, cognitive radio (CR) needs sensing and transmitting antennas that can be switched to transmit over a selected frequency band. This brought about to a raised the concern for the improvement of frequency switchable antennas to exploit the spectrum efficiently [1]. Switchable antennas are a sort of multi-purpose antenna with just one antenna is capable of replace the resonant frequencies, radiation pattern or polarisation in real time without changing the complete antenna's structure.…”
