Broadband high-gain GPS antenna

The utility model discloses a broadband high-gain GPS antenna. The antenna is fed through the micro-strip interconnection line, a radio frequency signal enters the IPD phase shifter chip through the micro-strip interconnection line, the signal in the IPD phase shifter chip is divided into two paths of signals which are equal in amplitude and have the phase difference of 90 degrees, and the phase of an output signal of the second packaging bonding pad lags behind the phase of an output signal of the third packaging bonding pad by 90 degrees. And an output signal of the second packaging bonding pad is connected to a second feed column of the antenna through a third microstrip interconnection line. An output signal of the first packaging bonding pad is connected to the antenna first feed column through the second microstrip interconnection line. The antenna has a good omnidirectional characteristic. 本实用新型公开一种宽带高增益GPS天线。天线通过微带互连线馈电，射频信号通过微带互连线进入IPD移相器芯片，在IPD移相器芯片中信号分为幅度相等，相位差90°的两路信号，其中第二封装焊盘的输出信号相位滞后于第三封装焊盘的输出信号
