ABSTRACT:
A broad-band microstrip antenna implemented using a dielectric base as its main body is disclosed. The base has two sides where the dual-mode resonator is located on the first side, while the grounded plane is located on the second side of the dielectric base. The dual-mode resonator has a high-frequency resonator and a low-frequency resonator, which are partially positioned in parallel. Due to the electric-magnetic effects, these two resonators are mutually coupled to significantly increase the operating bandwidth. In addition, there is a feed line on the first side of the dielectric base, which connects to the dual-mode resonator to provide signal transmission. In addition, there is a grounded mask in the antenna, which is located on the first side of the dielectric base, to provide sheltering for the feed line, and connect to the grounded plane to form a closed area to provide a more complete radiation field pattern.
