Abstract

This paper introduces a new design of bio-inspired maple leaf-shaped textile microstrip patch antenna for wireless applications. The proposed maple leaf-shaped antenna is designed to resonate in the C band frequency range of 6.6–8.9 GHz. The maple leaf-shaped radiating patch is excited with 50 Ω microstrip feed line. The proposed antenna uses a Jeans fabric substrate which has a dielectric constant of εr = 1.6 and a tangent loss of 0.003. By incorporating maple leaf-shaped structure in the radiating patch, it resonates for wideband frequencies with a fractional bandwidth of 29.67%. The maximum achievable gain of the designed antenna is 3.8 dBi. Using Ansoft HFSS software, the antenna radiation parameters such as VSWR, radiation pattern, gain, and return loss are simulated. The simulated results are examined and presented.
