Implementation of Broadband Printed Sleeve Monopole Antenna

This paper presents the broadband printed sleeve-monopole antenna implementing the sleeve monopole structure in the form of PCB. In the proposed antenna, the antenna performance was improved by the diameter variation of the radiator, the length variation of the sleeve, and the variation of the diameter of the sleeve conductor. HFSS simulator of ANSYS corp. was used in order to confirm the antenna parameter characteristic. According to the simulation results, the VSWR was less than 2 for the range of 2.12GHz?3.18GHz. The frequency bandwidth is 1.08GHz. The frequency range of the actual fabricated antenna was 2.0GHz?3.55GHz, the frequency bandwidth is 1.55GHz. The maximum gain was 1.64dBi. The proposed antenna was 56×5×1.6mm in size. The utilization possibility of the broadband printed sleeve-monopole antenna could be confirmed according to compare and analyze the simulation and measurement data.
