Abstract: In this article, a millimeter-wave bidirectional active integrated coplanar waveguide slot antenna with ball grid array (BGA) interconnection is proposed. Symmetric multistage step impedance resonator matching network and tapered shaped structures are utilized to ultrawideband compensate the reactance behavior of the vertical BGA transition, which can be employed to reduce the interconnection length among different modules. By gradually changing the width of the semielliptic slot, an ultrawideband radiation behavior is achieved with a small impedance variation from one resonate mode to another. The proposed 1 $\times $ 4 passive antenna array can operate from 25 to 40 GHz with a gain of 13.1 dB. Compared with the conventional active integrated antenna structures, good advantages of wide bandwidth and high gain are obtained with the proposed technique. The prototype of the presented active antenna array is fabricated and measured with a wide impedance bandwidth of 29.1–40 GHz and can be more suitable for high-solution radar sensor.
