Abstract
A most of portable devices, such as mobile phones, tablets, uses antennas made of cupper. In this paper we demonstrate possible use of electrically conductive polymer composite material for such antenna application. Here we describe the method of preparation and properties of the carbon nanotubes (CNTs)/(ethylene–octene copolymer) as flexible microstrip antenna. Carbon nanotubes dispersion in (ethylene–octene copolymer) toluene solution was prepared by ultrasound finally coating PET substrate by method of dip-coating. Main advantages of PET substrate are low weight and also flexibility. The final size of flexible microstrip antenna was 5 x 50 mm with thickness of 0.48 mm (PET substrate 0.25 mm) with the weight of only 0.402 g. Antenna operates at three frequencies 1.66 GHz (–6.51 dB), 2.3 GHz (–13 dB) and 2.98 GHz (–33.59 dB).
Highlights
Electronic devices use mainly copper based microstrip antenna for communication between each portable devices in network [1,2,3]
As the composite materials can perform several functions simultaneously, they can be applied to various products and surfaces in the ICT field. This contribution is focused on the use of carbon nanotubes in the passive antenna, which consists of a layer of carbon nanotubes and, applied to PET substrate

Summary
Electronic devices use mainly copper based microstrip antenna for communication between each portable devices in network [1,2,3]. In many fields of science, carbon nanotubes are one of the most promising materials. There are increasing possibilities for the use of carbon nanotubes in electronics. As the composite materials can perform several functions simultaneously, they can be applied to various products and surfaces in the ICT field. This contribution is focused on the use of carbon nanotubes in the passive antenna, which consists of a layer of carbon nanotubes and (ethylene–octene copolymer), applied to PET substrate. The antenna described in this article operates at three frequencies 1.66 GHz (–6.51 dB), 2.3 GHz (–13 dB) and 2.98 GHz (–33.59 dB)
