Abstract
The present invention relates to a low loss antenna switch. The antenna switch comprises a plurality of switch module and a plurality of transmitting/receiving terminals, wherein one end of each switch module is connected to an antenna unit and the other end of each switch module is connected to each transmitting and receiving end respectively. Further, each switch module comprises a plurality of switch units in series, wherein the width of at least one switch unit is smaller than other switch units of each switch module. Thus, the parasitic capacitance of the off-stage switch modules can be reduced, and VSWR (Voltage Standing Wave Ratio) of the antenna switch also can be improved.
