Design and Optimization of Rectangular Microstrip Patch Array Antenna Using Frequency Selective Surfaces for 60 GHz

摘要

Microstrip Patch Antennas (MPAs) are mostly known for their versatility in terms of possible geometries that makes them applicable for many different situations. The lightweight construction and the suitability for integration with microwave integrated circuits are two more of their numerous advantages. Patch antenna has a narrow bandwidth so it has a complexity in tunings. Also, MPAs are famous for their poor gain. So, there is a requirement to increase the bandwidth and gain of Microstrip Patch Antenna (MPA). This paper presents the application of Frequency Selective Surfaces (FSSs) in rectangular Microstrip Patch Array Antenna (MPAA) as a solution to improve radiation parameters of the array. A rectangular MPAA between two FSSs were proposed for 60 GHz applications. Several parameters have been significantly improved, in particular the gain, bandwidth, return loss, and radiation pattern, compared with an optimized antenna. Numerical and simulate results are presented.
