Abstract :

Beveled edge rounded bowtie antenna is proposed for UWB applications in this paper. Beveling technique is employed to increase the bandwidth of classical bowtie antenna. The simulated bandwidth is from 3 GHz to 11 GHz in order to observe the bandwidth enhancement in the frequency range of interest for UWB applications. Effective parameters of the antenna, including Return Loss (S11), Voltage Standing Wave Ratio (VSWR) and radiation pattern are examined for the proposed structure. Then behavior of the designed antenna is compared with the classical bowtie antenna and rounded bowtie antenna characteristics to verify the enhancement due to the beveled edge structure. Besides, it is demonstrated that the proposed antenna satisfies UWB requirements by providing return loss less than -10 dB and VSWR less than 2, respectively during the enhancement process. Beveled edge rounded bowtie antenna model is designed by using CST Microwave Studio Program which is an electromagnetic simulation auxiliary tool.
