This paper presents simulation and measurement results of a microstrip patch antenna at W band, fed by using simple solderless surface mount PCB connector. The antenna is designed on Rogers RO3003 board to be operated at 77 GHz, as the antenna of an automotive radar receiver. To calibrate the measurement setup, TRL (Through-Reflect-Line) calibration kit is also designed on the same PCB board. Antenna reflection coefficient is measured at W band with 2.5 GHz shift in resonant frequency due to board lower dielectric constant at the operating frequency. The antenna co-polarized radiation pattern is measured on patch H plane for a span of 100° at 77 GHz. The antenna has a measured and simulated gain of 5 dBi and 5.75 dBi at θ = 0° and 77 GHz, respectively.
