“…52 This design requires less power consumption than other methods that require constant voltage biasing to maintain a certain radiation mode. 53 The properties of the OFF state of the switch can be attributed to complex ion transport characteristics of the solid electrolyte that may increase the overall conductivity in the switch but result in slower diffusion of dopant ions, thus exhibiting a non-negligible dielectric loss. 54,55 At the same time, we cannot rule out incomplete dedoping of PE 2 due to its low oxidation potential.…”

“…The viability of this switch is facilitated by the capability of the CP film to remain in its ON or OFF state after the DC source is decoupled, so that the adverse effect of the biasing lines and DC source on the operation and performance of the antenna is lowered .

Conjugated polymers (CPs) undergo a wide range of reversible intrinsic property changes including electrical conductivity, electromagnetic absorption, volume, and charge mobility upon electrochemical oxidation/reduction, which has made them popular as ON/OFF organic-based switchable materials. Recent studies on the insulating-to-conductive transition within CPs have paved the way for a next generation of flexible switches that permit the creation of “dynamic” electric circuits. Here, we present an approach to a low-voltage, low-power electrochemically controllable, switchable, and printable CP-based conductive element that acts as a platform for the configuration of frequency-reconfigurable radiative antennas. We demonstrate that the DC conductivity of a soluble PEDOT derivative, PE2, film can be switched electrochemically by 4 orders of magnitude across large insulating gaps up to 15 mm within 20 s. Its integration in a DC switching element that is incorporated along the poles of a half-wave dipole antenna structure is able to generate an AC resonant frequency switch, and thus a radiation frequency shift, in the microwave (i.e., 1–2 GHz) range. This type of printable antenna fills an important need for the demand of bandwidth that is growing beyond the crowded frequency spectrum, by relying on the development of frequency-reconfigurable antenna systems capable of dynamically tuning their spectral properties when desired.

“…In [39], the concept of reconfigurable antennas is explained in detail and the authors also expand on the different methods used for implementing dynamic, reconfigurable antennas. These methods include electrical and mechanical switching which are also extended and looked into closely by the authors of [40]. As stated in [40], electrical reconfiguration through the use of PIN diode alters the flow of current in the antenna geometric structure, which modifies it's electrical characteristics.…”

Multiband Reconfigurable Antennas for 5G Wireless and CubeSat Applications: A Review

et al. 2022

The rapid development of wireless technology has sparked interest in multi-band reconfigurable antennas as devices and satellites are innovating toward miniaturization. With limited space, reliable and efficient high bandwidth antenna systems are needed for current and next-generation wireless technology as well as for the revolutionary small satellites. The fifth generation of mobile communication technology promises high data rates, low latency and good spectrum efficiency. One of the key enablers of this technology is the integration of satellite technology-particularly CubeSats with terrestrial communication technologies. Next-generation antennas that can meet functional requirements for 5G and CubeSat applications are therefore of fundamental importance. These antenna systems should have large bandwidth, high gain and efficiency and be compact in size. Reconfigurable antennas can provide different configurations in terms of the operating frequency, radiation pattern and polarization. Tuning reconfigurable antennas can be done by changing the physical parameters of the antenna elements through electronic switches, optical switches and the use of meta-materials. The most popular implementation method for

“…The state-of-the-art SoC solutions bring together different kind of fabrication processes such as GaAs, CMOS or Si/SiGe BiCMOS for RF purposes [40]. SoCs may also incorporate radio-frequency microelectromechanical systems (RF-MEMS) for switching [41], phase delaying [42] or capacitance tuning [43]. When the SoC implements different RF/mmW circuitry it receives the name of Monolithic Microwave Integrated Circuit (MMIC's).…”

Evaluation of a Planar Reconfigurable Phased Array Antenna Driven by a Multi-Channel Beamforming Module at Ka Band

et al. 2021

In this paper, a planar active phased array antenna demonstration with linear polarization (LP) at Ka Band (28-30 GHz) is presented. The proof of concept is carried out to evaluate the possible problems that may arise, to analyze possible calibration stages and to assess the viability of the integration of an active system with a Multi-Channel Beamforming Module (MCBM). To fulfill this task an 8x8-element planar array arranged in column subarrays of 1x8 elements for 1D beam steering is proposed. The single element consists of a printed circular patch connected to a microstrip feeding line through metallic vias in a multilayered structure. Both the amplitude and phase distributions are performed by a commercial integrated circuit (IC) designed for transmission purposes, from the common port to each of the 8 output ports. Thus, an evaluation of the IC performance is also included within this work. Despite the inherent amplitude and phase feeding errors of the IC, the beam-steering accuracy of the system is reasonable. A nice correspondence between the simulated and measured 8x8-element array beam steering directions is obtained, with errors below 1º in the steering of the beam.INDEX TERMS Active phased array, beam steering, antenna integrated circuit, Ka band antenna.
