Abstract: A fourth order orbital angular momentum (OAM) four patch antenna is described. The antenna includes a dielectric substrate, a metallic sheet, and a four patch antenna. The four patch antenna includes a circular ring path patch, a first feed branch patch, and a second feed branch patch. The first feed branch patch is connected to the circular ring path patch. The second feed branch patch includes a straight leg which extends radially from the circular ring path patch and a curved leg having a first end connected to the straight leg and a second leg connected to the first end of feed port patch. The antenna is configured to resonate in a fourth order OAM mode at a frequency of 5.12 GHz when an electrical input signal is applied to a second end of the feed port patch.
