“…a tolerable return loss is sufficient. A minimum return loss of 6 dB is considered adequate to have tolerable impedance matching and power transfer for an antenna with beam steering characteristics [16]. In that case, regardless of the switching modes at 5.8 GHz operation, the proposed antenna maintains reflection coefficient of less than −10 dB for RD and DR-modes and less than −8 dB for the DD-mode.…”

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.

“…The existing beam-steering antennas can be approximately categorized into four groups: 1) array antennas with phase control technology [1]- [5]; 2) liquid-metal antennas [6]- [7]; 3) antennas with parasitic techniques [8]- [15]; 4) circular-shaped electronically-controlled 360° beam-switching approach [16]- [24]. As an advanced function, the configuration of beam-steering antennas are normally very complicated, which causes conventional beam-steering antennas face the challenges of high profile (vertical plane), large size (horizontal plane), relatively high cost, limited bandwidth, low efficiency and limited beam-steering angle for the approaches in 1) and 3).…”
