摘要：
In this paper the low-loss ridge-gap waveguide technology is used to feed system of travelling-wave leaky-wave slot antenna in the Ku bands. The two main section of the 1-D and 2-D planar slot array antennas are designed. The planar 1-to-4 gap-waveguide power divider is designed, where by each of its four branches feeds a linear slot array of the planar array. The computer simulations are performed by commercial software of CST Studio. The planar array has the broad side spatial scannability in the range of angles from -29 to 29 degrees. The designed slot array antenna has achieved the radiation performance of impedance bandwidth of 56%, in center frequency of 12.5 GHz.
