Microstrip patch array antennas based on conventional geometries

In this paper, a comparative study of Microstrip patch array antennas based on conventional geometries was performed. First, single element patch antennas with rectangular, circular, triangular and hexagonal geometry were studied based on the Transmission Line Model (TLM). The results have been optimized and validated by CADFEKO a solver which is based on the Method Of the Moments (MoM). Thereafter, we compare the performances of the antennas versus the geometry shape. Next, two and four elements for each geometry are studied in order to analyze their effect on the HPBW (Half Power Beam Width) and the total gain.
