Multilevel advanced antenna for motor vehicles

The present invention is equipped with the following components and features about the antenna for cars. (a) The transparent windowpane in which at least one side is optically covered on the transparent electric conduction plate in [of the window material plates] one, (b) a set of polygon elements which are the multilevel structure printed on the electric conduction plate, and belong to a certain same kind -- desirably, The same impedance in two conductors, the multilevel structure which consists of a triangle or a square, and the object for (c) transmission-line feeding power, and (d) feeding power point, and the level radiation figure in three of at least three zones. Two of these three frequency are chosen from what is shown below. FM, DAB, a tire pneumatic control system, the radio opening for vehicles, Tetra, DVB, GSM900/AMPS, GSM1800/DCS/PCS/DECT, UMTS, GPS, Bluetooth, and wireless LAN. The typical frequency band of these various uses is as follows. FM (80 MHz * 110 MHz), DAB (205 MHz * 230 MHz), Tetra (350 MHz * 450 MHz), the radio opening for vehicles (433 MHz * 868 MHz), A tire pneumatic control system (433 MHz), DVB (470 MHz * 862 MHz), GSM900/AMPS (820 MHz * 970 MHz), GSM1800/DCS/PCS/DECT (1700 MHz * 1950 MHz), UMTS (1920 MHz * 2200 MHz), Bluetooth (2400 MHz * 2500 MHz), and wireless LAN (4.5 GHz * 6 GHz). The main advantages of the present invention are in the multiband multiservice performance of an antenna. In this, a simple antenna enables it to connect with almost all the communications system for vehicles conveniently and simply.
