Summary:
This paper presents a design of a wideband printed antenna being useful for ultra-wideband applications. In the designed antenna that operates over the frequency band of 7-10 GHz, a leaf-shaped bowtie slot antenna (LSBSA) is employed as a radiating element, and electromagnetic coupling feed based on a microstrip line is adopted for the excitation of the radiating element. In order to demonstrate the effective performance of the presented configuration, characteristics of the designed LSBSA are evaluated by the finite-difference time domain (FDTD) analysis. Over the above-mentioned frequency band, the simulated reflection coefficient is observed to be less than -10dB, and the maximum actual gain of 7.5dBi is obtained. Measured results are also presented in order to validate the simulated results.
