Wide-Band Antenna on Flexible and Thin Substrate for Wireless Systems

Abstract

This paper presents the design of a flexible monopole antenna for wideband applications. The proposed antenna is printed on flexible substrate material having a dielectric constant of 3 for the design and fabrication of the proposed antenna. The antenna dimensions are 3.8 cm × 4.1 cm × 0.025 cm. The antenna characteristics are investigated not only in flat conditions but also under bending configuration. Both flat and bending configurations are operated at frequency bands from 2.4 GHz up to 10 GHz with S- parameters lower than − 10 dB. The antenna parameters such as gain, efficiency, and radiation patterns are studied for both configurations. A deep study for time-domain response is discussed to validate the performance of the proposed antenna to operate at a wide band with a highly correlated response.
