Abstract

A monopole disc antenna for multi band system operation is presented. The operating frequency of the proposed in-building antenna includes the GSM 900, GSM 1800 and 3G bands. The antenna structure consists of a two-steps cylinder combined with a circular disc to provide broadband characteristics. This antenna has a VSWR les 1.5 and an omni-directional radiation pattern at all bands. The proposed monopole disc antenna was designed according to stringent electrical and mechanical specifications. In this paper, both simulated and actual measurement results are presented. In addition, we have included a walk-test (field trial) result to verify the antennas performance in an in-building environment.
