Abstract: The objective of this paper to design eight elements (4×2) antenna array with hybrid feed structure. A number of microstrip antenna arrays such as microstrip antenna with inset feed, 2×1 antenna array, 4×1 antenna array and 4×2 antenna array have been designed using Rogers RT/duroid 5880 as dielectric materials are proposed to enhanced gain and bandwidth in practical measurement. The simulated gain is 14.917 dB obtained with hybrid feed structure and bandwidth of the design is 396.8 MHz and 523.5 MHZ at 9.4 GHz and 11.6 GHz resonating frequency. A prototype of the antenna is also constructed and tested, the tested results shows a bandwidth of 500 MH z. Loss increases due to long feed transmission line which reduce the gain of the antenna when we use thicker substrate. So hybrid feed structure is used in this design to reduce the length of transmission line. The application of this design is in radio location.
