Broadband Microstrip Omni-Antenna Design for Mobile Communication System

With the rapid development and growth of the communication industry, the commutation system has higher and higher requirements for the performance of antennas. The radiation of omni-antennas can cover the angular range of all directions. Its simple structure, low cost, and miniaturization make it more and more popular. More and more scholars have paid attention to the wide-band omni-directional microstrip antenna research, which has a wide range of application prospects and practical significance. This article takes the mobile communication system as the background, designs and realizes a broadband omni-antenna. The antenna is based on an array of doublet antenna, with triangular balun balanced feed, which effectively broadens the bandwidth of the antenna through electromagnetic coupling feed, all indicators meet the requirements, and the simulation results match the actual test results well.
