摘要：
The design of microstrip patch array with horizontal polarization for ISRA radar is presented in this paper. The first step of this research is designing a single antenna element. To increase the gain and to narrow the beamwidth, each single antenna is then arranged as the 5x1 and the 5x4. To obtain horizontal polarization, a rectangular slot is located on the right side of the bottom patch. Antenna array consists of a 20 square-shaped patch with uniform distribution to the vertical and horizontal directions. The results showed an antenna array has a resonant frequency of 9.3 GHz with reflection coefficient value of -31.93 dB. The resulting gain of the antenna array is 17.9 dB whereas the vertical and horizontal beamwidth antenna array is 16,8 degrees and 21,4 degrees. An antenna feeding uses a proximity technique which utilizes two substrates, the transmission line on the bottom substrate and the patch antenna on top of the substrate. This technique can increase the bandwidth of the antenna by 59.36%.
