Abstract

In this paper, a new design for a coplanar waveguide (CPW) fed, aperture antenna is introduced. This CPW aperture antenna is designed at a central frequency around 10 GHz with an input impedance of approximately 50 Ω. Numerical simulation is performed for antenna analysis using Momentum from the Advanced Design System (ADS) software package of Agilent Technologies. The bandwidth of this basic bow-tie aperture antenna is about 1 GHz and the return loss approximately -18 dB. Another advanced design for this basic bow-tie aperture antenna shows a bandwidth of 1.3 GHz with a return loss of -40 dB around 10 GHz. Simulation results for return loss, input impedance and radiation pattern are presented. These characteristics make these two antennas suitable for antenna arrays for radar applications.
