Abstract
In this paper, the broadband cross monopole antenna is presented and the radiation characteristics is investigated f3r various width and height of the radiated element. In the presented antenna, the broadband characteristics is realized by the cross monopole element and the impedance matching section between the element and the ground. To conform the broadband characteristics of the presented antenna, the experimental antenna is designed, fabricated, and its radiation characteristics are measured in $1.75\~2.655$ GHz. It is shown that the designed antenna has the nondirectional pattern in the horizontal plane, the directional pattern in the vertical plane, VSSR less than 1.5, and gain in $2.5\~3.78$ dBi. From these results, the presented antenna is conformed as a broadband indoor antenna which can be used for PCS, WCDMA, Wibro, and satellite DMB band.
