A Modified 60 GHZ Rectangular Patch Antenna with Slots and Parasitic Structures for V-Band Usage

This study proposes a modified rectangular patch antenna achieving efficient performance at 60GHz thus providing applications in V-band. It has been designed and simulated using Ansys HFSS software. It achieves a return loss of -42.96dB at 60.1GHz and -27.15dB at 60GHz which is an essential parameter for assessing performance, particularly in high-frequency applications like 60 GHz systems, where effective impedance matching is essential for optimal radiation. The antenna is built on a efficient substrate which is with a thickness of 0.254 mm. In this design, the radiating element is a conductive patch placed on the dielectric substrate. A conductive microstrip feedline is directly integrated with the patch to directly deliver the signal to the radiating element. It has compact dimensions of 6.2 x7.4 x0.254 mm<sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">3</sup> which is suitable for high frequency applications where smaller and precise geometries help achieve optimal performance.
