Embodiment
In order to reduce lower deployment cost, need the quantity reducing the transponder of affixing one's name in the middle part of track.And the safety traffic that can ensure train is wanted when reducing the quantity of transponder, need the reading window increasing transponder.One be easy to expect for increase the reading window scheme of transponder be increase transponder in the size of antenna element, but the antenna element increased needs larger space to hold, and this needs change transponder to increase the enclosure interior space of transponder.But the shell dimension of transponder normally can not arbitrarily change, therefore, the reading window being increased transponder by the size increasing the antenna element in transponder is usually infeasible.
Below, each embodiment of the present invention will be described by reference to the accompanying drawings in detail.
Fig. 3 shows the schematic diagram of transponder according to an embodiment of the invention.As shown in Figure 3, transponder 10 can comprise antenna assembly 20, switch element 30 and controller 40.
