An All-Textile Louis Vuitton Logo Antenna

Abstract

An all-textile Louis Vuitton logo antenna is proposed. For proper antenna design, the electrical properties of various leathers are measured. The crossed LV-shaped logo is composed of two longer thin arms for the lower frequency band and two shorter thick arms for the higher frequency band. The proposed logo antenna is fabricated from a conductive textile and a leather substrate, and it has an appropriate logo size for practical bag utilization. The proposed antenna operates in the industrial, scientific, and medical 2.45 GHz band and in the 4.5 GHz band. The corresponding fractional -10-dB reflection coefficient bandwidths and maximum gains are 17.1% and -0.29 dBi, respectively, for the lower frequency band and 13% and 3.05 dBi, respectively, for the higher frequency band.
