The present invention discloses a four-mode defected ground structure resonator, comprising a metal dielectric substrate and a defected ground unit which is etched in one surface of the metal dielectric substrate; the shape of the defected ground unit is axially symmetric about a first central axis of the defected ground unit, and also the shape of the defected ground unit is axially symmetric about a second central axis of the defected ground unit; the first defected ground unit is provided with H-shape or quasi H-shape, the second defected ground unit is provided with L-shape, quasi L-shape, U-shape or quasi U-shape. The four-mode defected ground structure resonator of the present invention is provided with four types of resonant modes, and the four types of resonant modes are provided with good tunability.

Four-mode defected ground structure resonator

Disclosed is a four-mode defected ground structure filter, including a four-mode defected ground structure resonator and two microstrip feed lines. The four-mode defected ground structure resonator comprises a metal dielectric substrate and a defected ground unit which is etched in one surface of the metal dielectric substrate; the microstrip feed lines are arranged at another surface of the metal dielectric substrate; shape of the defected ground unit is axially symmetric about a first central axis of the defected ground unit, and is axially symmetric about a second central axis of the defected ground unit; the first defected ground unit is provided with H-shape or quasi H-shape, the second defected ground unit is provided with L-shape, quasi L-shape, U-shape or quasi U-shape.

Four-mode defected ground structure filter

The present invention provides a switching method of the different display windows of a TV. Before the switching, the TV displays the TV programs, received from the broadcast system and a server, in a main window and a sub-display window respectively, and the switching method includes the following steps that: the TV and the server determine the channel identifiers of the TV programs displayed by each other; the TV displays the TV programs, received from the broadcast system and the server, with the channel identifiers of each other using the first display window and the second display window respectively. By the present invention, the sources of the contents displayed respectively in the first display window and second display window do not change, thereby maintaining the respective display quality (including resolution and picture size) of the two display windows unchangeable before and after the switching.
