Many scientists and researchers have now focused on the terahertz band. Therefore, terahertz waves have advantages that microwaves cannot have: the transmission quantity is large, and when the terahertz antenna is used in a communication system, the antenna can obtain the transmission speed of 10 Gbit/s. With continuous breakthrough and development of THZ technology, devices working in the THZ frequency band become hot spots for domestic and foreign research, wherein THZ filters of THZ antennas and the like are important directions for research.
DGS (defected ground structure) is an aperiodic or periodic cascade configuration defect provided in the ground plane of a coplanar or microstrip or conductor-backed coplanar waveguide. This drawback is provided to disturb the current distribution of the patch antenna, which in turn is due to variations in the characteristics of the effective capacitance and inductance of the microstrip patch antenna.
