The main research content of this paper is: 1. The performance index of integrated antenna of handheld terminal is proposed in the research and combination project of the prototype of integrated antenna of handheld terminal. Firstly, according to the basic theory of the second chapter, the paper points out the difficulties in the design of the integrated antenna of the handheld terminal. The design scheme of the antenna is given, and the design scheme of the integrated antenna of the handheld terminal is simulated and analyzed by using the electromagnetic simulation software in this paper. The simulation results show that the VSWR of the antenna in its working band is less than 2.0, and the circular polarization characteristics are good. The isolation of each antenna is greater than 14.0dB. on this basis. The experimental prototype of the antenna is processed, and the electrical performance of the antenna is tested. The test results show that the integrated antenna of the hand-held terminal has good standing wave performance in its working band. Under the condition of limited size, the requirement of high isolation is reached. 2. The development of the experimental prototype of broadband dual-polarization antenna is aimed at the technical requirements of broadband dual-polarization antenna. In this paper, the related concepts and research status of microstrip antenna are introduced, and the difficulties of designing the antenna with wide band, double polarization and high isolation are pointed out. The design scheme of the antenna is given. The broadband dual-polarization antenna is designed and analyzed by electromagnetic simulation software, and the experimental prototype of the antenna is fabricated on the basis of simulation optimization. According to the test results, it can be seen that the voltage standing wave ratio of the designed broadband dual-polarization antenna is less than 2.5 in its working band. At the same time, it meets the requirement of high isolation between two ports, and has certain engineering application value.
