The length of the square patch is taken as L = 3 cm and substrate
parameters are e r = 2.55, h = 0.159 cm, and tan d = 0.001. When isosceles
right angle triangular patches of side length l = 0.35 cm are removed from
the two corners, LHCP is obtained for the feed at x = 0.65 cm. The BWs
for AR £ 3 dB and VSWR £ 2 are 30 MHz and 93 MHz, respectively,
centered at f 0 = 2.963 GHz.
