Abstract:
A broad-band microstrip antenna, comprising:a dielectric base having a first side and second side, wherein the first side and the second side are opposite to each other;a dual-mode resonator, located on the first side, wherein the dual-mode resonator comprises a high-frequency resonator and a low-frequency resonator mutually coupled together, and each of the high-frequency resonator and the low-frequency resonator has a line-like structure with at least two right-angle bent structures so that the dual-mode resonator comprises a parallel partial portion between the high-frequency resonator and the low-frequency resonator;a feed line, located on the first side, wherein the feed line is coupled to the dual-mode resonator; anda grounded plane, located on the second side, wherein the grounded plane is opposite to the feed line.
