Abstract

This paper presents a narrow notch band, flexible, wearable ultra-wideband antenna built on a jeans substrate. Prior to designing the antenna, the dielectric properties of the jeans substrate are experimentally investigated. The effects of antenna shape and substrate loss characteristics on resonant performances are discussed with reference to the notch characteristics. The proposed antenna is shaped like a cumulative rugged element, with two identical legs. The investigation of the designed antenna shows the operating frequency ranges (S₁₁ ≤ -10 dB) in 2.4-4.2 GHz and 5.86-10.7 GHz bands with notch properties in telemetry/mobile communications (4.4-4.99 GHz) and WLAN (5.15-5.85 GHz) band. Additionally, the prototype is investigated under on-body conditions. Measured results are also included for the validation of the designed prototype.
