Abstract: This paper proposed a dual-sleeve broadband omnidirectional antenna based on end-loaded technology, the antenna presents a new type of end-load and the special dual-sleeve structure. The working frequency of the dual-sleeve broadband antenna based on end-loaded technology ranges from 57 MHz to 103 MHz, where the voltage standing wave ratio (VSWR) is less than 1.5(which means the S11 <-13.98dB),the antenna's relative bandwidth is 57.5% and the impedance bandwidth is 1.81 ：1. Simulation results agree well with the test results, the results also show that the antenna has a gain of more than 2dB in the setting frequency range and is omnidirectional in the H plane.
