Abstract :
A single layer wideband SIW-fed differential patch array is proposed in this paper. A SIW-CPS-CMS (substrate integrated waveguide - coupled lines - coupled microstrip line) transition is designed and has a bandwidth of about 50%, covering the E-band and W-band. The differential phase deviation between the coupled microstrip lines is less than 7.5° within the operation band. A 1×4 array and a 4×4 array are designed. The antenna is composed of SIW parallel power di vider network, SIW-CPS-CMS transition, and series differential-fed patch array. Simulated results show that the bandwidth of the 1×4 array and 4×4 array are 37% and 12%, and the realized gain are 10.5-12 dB and 17.2-20.2dB within the corresponding operation band, respectively. The features of single layer and wideband on impedance and gain of the proposed SIW-fed differential patch array make it a good candidate for automotive radar or other millimeter wave applications.
