PURPOSE: An HSPDA antenna design method for a vehicle is provided to maximize the performance of an HSPDA antenna by installing the HSPDA antenna in the head unit of the vehicle. CONSTITUTION: In an HSPDA antenna design method for a vehicle, the position of the HSPDA antenna for a vehicle is determined(S101). The reflection loss of the antenna is measured(S102). The emissivity of the antenna is measured at(S103). The reflection loss and emissivity of the antenna at each position are compared(S105). An optimized antenna position is selected(S106).
