“…The radiation efficiency of antennas in thin film processes is usually a critical issue [8]. This is mainly caused by the high intensity of the electrical field in the thin dielectric substrate, which in turn contributes to a high surface current in the rather thin metal layers and eventually an increase in conductor losses.…”

In this work we assess the feasibility of fabricating a matrix of antennas for the millimeter (mm)-wave band using the “Multi Chip Module – Deposited (MCM-D)” process. The main focus of the design is to minimize the cross coupling between the antennas fabricated on the common substrate. We investigate the use of a virtual cavity formed by metalized vias in order to reduce the cross coupling to the neighboring cells. The radiation efficiency is analyzed in detail, and experimental results of a 2 × 2 array are presented.

“…Thus these are very attractive materials for conformal applications which require antenna characteristics including flexibility, light weight and low cost. Some polymer-based narrow band patch antennas using polyaniline (Pani) [6], polypyrrole (PPy) [7] and poly 3, 4-ethylenedioxthiophene (PEDOT) [8] as well as some Ultra-Wideband (UWB) antennas using the latter two materials [9] have been previously reported, showing limitations in mechanical flexibility and efficiency. However, these reports have indicated the promising potential of conductive polymers as antenna materials.…”

A compact, highly efficient and flexible ultrawideband antenna operating from 3 to 20 GHz is proposed in this letter. The antenna is completely made from polymer comprising a patterned conductive polymer (PEDOT) thin film attached to a transparent sticky tape substrate. The overall dimension is less than a quarter-wavelength at the lowest frequency of operation and the device reaches a radiation efficiency of over 85% averaged throughout the frequency band. The antenna performs well under various bending conditions as demonstrated by measurements. The realized antenna offers great mechanical flexibility and robustness which indicates its promising potential for possible seamless integration in flexible electronics.

“…Later researchers moved on to the usage of carbon nanotubes [ 11 , 12 ] or other very good conductors (silver and gold particles) to increase electrical conductivity [ 13 , 14 ]. The use of carbon nanotubes has led to technologies using PANI and carbon fibers (PANI-MWCNT) [ 15 , 16 ], technologies using polypyrrole (PPy), [ 17 ] and PPy combined with PEDOT materials [ 18 , 19 ]. Technologies using pure PANI exhibit DC conductivity around 4500 S/m [ 15 , 16 ].…”

Polyurethane-Carbon Nanotubes Composite Dual Band Antenna for Wearable Applications

The design of a unipole and a dual band F-shaped antenna was conducted to find the best parameters of prepared antenna. Antenna radiator part is fully made of polymer and nonmetal base composite. Thermoplastic polyurethane (PU) was chosen as a matrix and multi-wall carbon nanotubes (MWCNT) as an electrical conductive filler, which creates conductive network. The use of the composite for the antenna has the advantage in simple preparation through dip coating technique. Minor disadvantage is the usage of solvent for composite preparation. Composite structure was used for radiator part of antenna. The antenna operates in 2.45 and 5.18 GHz frequency bands. DC conductivity of our PU/MWCNT composite is about 160 S/m. With this material, a unipole and a dual band F antenna were realized on 2 mm thick polypropylene substrate. Both antenna designs were also simulated using finite integration technique in the frequency domain (FI-FD). Measurements and full wave simulations of S11 of the antenna showed good agreement between measurements and simulations. Except for S11, the gain and radiation pattern of the antennas were measured and simulated. Maximum gain of the designed unipole antenna is around −10.0 and −5.5 dBi for 2.45 and 5.18 GHz frequency bands, respectively. The manufactured antennas are intended for application in wearable electronics, which can be used to monitor various activities such as walking, sleeping, heart rate or food consumption.
