“…They offer miniaturization with no loss of functionality, fast actuation techniques, very low insertion loss, and extremely linear. Even though MEMS have only a few drawbacks, such as the need for costly transformers to provide high DC-bias voltages (40 V to 100 V), they are still difficult to integrate on PCB and they are still expensive [4]. In contrast, Gallium Arsenide (GaAs) and CMOS switches are relatively low cost and easy to integrate with RF circuitry.…”

In this paper, an electronically pattern reconfigurable antenna for Internet of Things (IoT) applications is presented. The antenna consists of 4 wire-patches sharing the same ground plane. This radiating element can switch between four end-fire radiation states in less than 5 us and achieves a 290 MHz frequency bandwidth from 2.25 to 2.54 GHz. The results show that this antenna can realize a peak gain of 3.9 dBi at 2.44 GHz and a front-to-back ratio greater than 6.5 dB. A single low-power, low-insertion loss SP4T switch enables the radiation pattern steering. This approach avoids the use of multiple electronic components in the reconfiguration mechanism, thus accommodating the IoT microcontroller's limited resource constraints. The antenna structure is compact and printed on two cost-effective FR-4 printed circuit boards (PCBs). Thanks to its high performance, small size, low cost, and lowpower characteristics, the proposed structure is suitable for IoT applications.

This article presents the development of a conformal reconfigurable frequency circularly polarized jute textile antenna, working at 2.4, 3.5, 5.8, and 5.9 GHz in Wi-Fi, Wi-MAX, Industrial, Scientific and Medical radio bands and W-LAN. The antenna topology is based on a semicircular structure as the main radiating component. The conductivity is realized by using copper paint, which was brush-painted. The patch structure is rehashed in another side of the substrate against the ground with a rotation turn 180. Two BAR64-03 W PIN diodes switches are placed in between a semi-elliptical structure and a rectangular structure on the bottom side of the ground plane. By governing the state of the switches, this antenna can operate at different operating frequencies. Furthermore, the antenna has an accomplished axial ratio (AR) of less than 3 dB for resonating frequencies at all four switching states. Other electromagnetic properties of the proposed jute textile antenna accomplished in simulations were confirmed through the measurement of the antenna in an anechoic chamber. The reconfigurable circularly-polarized jute textile antenna shows a peak gain of 4.93, 5.67, 8.86, and10.07 dBi at 2.4, 3.5, 5.8, and 5.9 GHz (Wi-Fi, Wi-MAX, ISM, W-LAN).

In this article, a deca-port carbon fiber-based multiple-input-multiple-output (MIMO) antenna with pattern diversity is presented. The radiating elements of the proposed antenna consist of low cost, light weight, environmental friendly graphite material. The 10 radiating elements of the MIMO antenna are arranged in a group of two (termed as sub-MIMO structure), in a cubical manner to cover all the propagating directions. Furthermore, the two carbon fiber-based radiating elements of the sub-MIMO structure are placed in an orthogonal arrangement to generate different radiation patterns. The antenna exhibits high inter-element isolation and low envelope correlation coefficient due to orthogonal placement of the radiating elements. The antenna is fabricated and the measured results confirm that the proposed MIMO/diversity antenna may be useful for vehicle-to-network applications. The MIMO performance parameters such as diversity gain, total active reflection coefficient, mean effective gain, channel capacity loss are evaluated and found within suitable limits. The three-dimensional pattern diversity helps to communicate in all directions.
