Design of ultra-wideband textile antenna for TV broadcasting

Abstract

Digital television (DTV) has been adopted in many places throughout the world, and it is received in different device types, such as laptops, portable media players, and smartphones. However, the current antennas used in these devices to receive DTV channels have drawbacks, such as low performance and non-practical physical structure in many situations. This paper presents a flexible, lightweight, and thin textile antenna for DTV, operating at an ultra-wideband (UWB) of 200 MHz–800 MHz and capable of being embedded in a garment or bag, making it easily transportable when folded. The antenna operation was simulated and measured to verify its performance, and based on the measurement results, the proposed flexible textile antenna was confirmed to have good performance, even in real conditions
