“…As a ferroelectric material, Ba x Sr 1−x TiO 3 could change its dielectric constant upon polarization in the electric field. By applying a voltage between the ground plane and patch (with a DC electric field changing from 0 to 10 V/μm), the change in the dielectric constant of the substrate leads to an increase of 10% in the resonance frequency of this reconfigurable antenna (Figure 6A) [111].…”

Wireless technology plays an important role in data communication and power transmission, which has greatly boosted the development of flexible and stretchable electronics for biomedical applications and beyond. As a key component in wireless technology, flexible and stretchable antennas need to be flexible and stretchable, enabled by the efforts with new materials or novel integration approaches with structural designs. Besides replacing the conventional rigid substrates with textile or elastomeric ones, flexible and stretchable conductive materials also need to be used for the radiation parts, including conductive textiles, liquid metals, elastomeric composites embedding conductive fillers, and stretchable structures from conventional metals. As the microwave performance of the antenna (e.g., resonance frequency, radiation pattern, and radiation efficiency) strongly depend on the mechanical deformations, the new materials and novel structures need to be carefully designed. Despite the rapid progress in the burgeoning field of flexible and stretchable antennas, plenty of challenges, as well as opportunities, still exist to achieve miniaturized antennas with a stable or tunable performance at a low cost for bio-integrated electronics.

“…The resistivity of this wafer was high (reduce the effect of dielectric on antenna's radiation characteristics) to increase the antenna gain and bandwidth. This method will greatly improve the integration of antenna system, and it makes the silicon-based reconfigurable antenna easily integrated into communication systems, such as vehicle electronic, UAV systems, smartphone chips, and IC systems [8][9][10][11]. Thus, these silicon-based miniaturized antennas have a great effect for the development of the communication systems, and this method plays an important role in guiding the research of silicon-based solid state plasma reconfigurable antennas in our future work.…”

In this paper, an on-chip high integration reconfigurable dipole with band stop filters was demonstrated. This antenna was fabricated on a high resistivity silicon wafer, and several optimized band stop filters were introduced into antenna system to replace conventional inductors and capacitors. The measured results show that the stopband of this filter can meet the requirements of the designed dipole. This method will greatly improve the integration of antenna system. On the basis of structural optimization, the proposed reconfigurable dipole realized two resonant frequencies at 1.33 GHz and 1.65 GHz, and the radiation patterns also showed satisfactory results.

“…BST has been utilized in various reconfigurable devices as a BST-based varactor. [18][19][20][21] In most of these devices, BSTbased varactors are typically utilized in a coplanar-plate under the device or under Interdigitated Capacitors (IDCs) where IDCs are placed on top of a thin or thick BST film. 13 BST has been fabricated as a thick or thin film using conventional fabrication techniques including mask development and photo lithographic processes.…”

This article presents a printed tunable right/left-handed leaky wave antenna (LWA) on a new flexible, tunable low density polyethylene-barium strontium titanate composite substrate using an aerosol jet printer. The new substrate had a dielectric constant of 16 and tunability of 3.5% at f = 10 GHz. Interdigital capacitors (IDC) were utilized in the leaky wave antenna design not only to act as shunt capacitor in CRLH transmission line design but also as tunability element to implement tuning capability of the LDPE-BST substrate for antenna beam steerability for a fixed operated frequency in X-band frequency range. Up to 15 beam steering was achieved by applying DC voltage through the printed leaky wave antenna.
