摘要

In this paper, a new planar bowtie-shaped antenna has been proposed for UWB wireless applications. The antenna is designed on FR4-substrate and fed by 50 Ω microstrip feed line with two quarter wavelength transformers for better impedance matching. The bowtie right side has a horizontal slit to enhance the bandwidth and it is connected to the microstrip feed line, while its left side is connected to the partial ground plane in the back side through shorting pin. The proposed antenna is investigated using the high-frequency structure simulator (HFSS). The simulated scattering parameter S11 (Reflection Coefficient) result shows bandwidth ranges from 3.05 to 10.8 GHz at return loss (RL = |S11|) ≥ 10 dB. The proposed antenna has high gain value, omnidirectional radiation pattern in the H-plane and mushroom-Shaped in the E-plane at lower frequency edge are achieved.
