“…The use of rigid substrate restricts their application in wearable technology as it may become uncomfortable to users. Other two antennas in [12] and [13] were implemented on flexible substrate, performing only frequency reconfiguration. The flexible antenna proposed in [16] is capable to perform frequency reconfiguration between two frequency bands and LHCP configuration is achieved only in the lower frequency band.…”

“…Nowadays, reconfigurable antennas in wearable technology are highly demanding for various applications. Several groups have achieved either the frequency reconfigurability [12], [13] and or the pattern reconfigurability [14], [15] in wearable technology. In [12], two GaAs hy-perabrupt varactor diodes are placed between the parasitic patch and the radiator which play the key role in achieving continuous frequency reconfigurability.…”

The conductive fabric radiator along with lumped elements is completely encapsulated within flexible polydimethylsiloxane (PDMS) layers to ensure physical robustness of the antenna even under severe deformation and washing.…”

A combined frequency and polarization reconfigurable textile based wearable disc monopole antenna is proposed in this paper. The antenna consists of a disc monopole as the radiator and four PIN diodes for realizing the agility property. By varying the different switching combination of the PIN diodes, frequency reconfigurability is achieved between the GSM and ISM band. Two circular polarization states, right hand circular polarization (RHCP) and left hand circular polarization (LHCP) are also realized in each operating frequency band. The upper band polarization state is controlled by an L shaped stub introduced in the ground plane whereas the lower band polarization agility depends on the length of the parasitic arc placed around the main radiator. The antenna is fabricated and its performance is measured to validate the proposed design.

This paper presents a novel reconfigurable filtering antenna with three tunable states used for IoT applications. The frequency reconfigurability is achieved using the combination of a hairpin filter and an open loop filter in the structure with the switching of p-in diodes. The open-loop filter structure provides two narrow band states at 2.4 GHz and 7.8 GHz, and the hairpin filter provides a single narrow band state at 10.4 GHz. The frequency reconfiguration is obtained without compromising the compact size of the designed circuit along with the targeted frequency bands at lower WLAN (2.47 GHz), WiMAX (3.42 GHz), INSAT C-band (7.18 GHz), fixed/mobile satellite service in X-band (8.4 GHz), direct broadcast service in Ku-band (12.14 GHz) applications. The prototype is constructed on an FR4 substrate and tested for validation in an anechoic chamber. The designed antenna provides excellent radiation characteristics and considerable gain at resonant frequencies. The proposed reconfigurable antenna is also tested using the CDAC Cmote device in the real-time environment and found more suitable for the IoT based communication applications.

A compact coplanar wave guide fed flexible monopole antenna on textile substrate is presented in this article. It consists of H and two concentric C slots. The H slot excites multiple band and the two concentric C slots improve the bandwidths. Measured impedance bandwidths are observed to be 1.5‐3.0 GHz and 4.5‐6.5 GHz for the first and second bands, respectively. Electromagnetic band gap structure has been used to achieve low specific absorption rate. The antenna has a compact size of 0.367 × 0.367λ. A sample was fabricated and experimentally characterized to verify the design concept and to validate the simulated results.
