Abstract

In this paper, a millimeter-wave power divider based on gap waveguide technology is designed for use in the feeding network of a slot array antenna. The simulation results demonstrate that the proposed structure has about 10% matching input bandwidth in the 58-64 GHz frequency range. The significant advantage of using gap waveguide technology is that there is no requirement of good electrical contact among different metallic parts of the low-loss structure which considerably simplifies the manufacturing processes and mechanical assembly at millimeter-waves applications. Finally, a planar slot array antenna is designed with sidelobe level of-23 dB and bandwidth of 4. 1% at the center frequency of 60 GHz. The gain of antenna is higher than 21. 7 dB over the operation bandwidth from 58. 8 to 61. 25 GHz, corresponding to efficiency larger than 88%.
