A circularly polarized fractal boundary microstrip
\r\nantenna is presented. The sides of a square patch along x- axis, yaxis
\r\nare replaced with Minkowski and Koch curves correspondingly.
\r\nBy using the fractal curves as edges, asymmetry in the structure is
\r\ncreated to excite two orthogonal modes for circular polarization (CP)
\r\noperation. The indentation factors of the fractal curves are optimized
\r\nfor pure CP. The simulated results of the novel polyfractal antenna
\r\nare demonstrated.<\/p>\r\n","references":"[1] Wen-Shayang, C., W. U. Chun-kun, and K -L.
