Square planar monopole antenna [PDF]
A broadband square monopole antenna is investigated, showing a constant radiation pattern over the impedance bandwidth. A simple formula for the frequency corresponding to the lower edge of the impedance bandwidth, which has an accuracy of ±8.5% over the frequency range 1 GHz to 6 GHz, is proposed. The effect of the feedgap distance is examined.

Annular planar monopole antennas
A type of annular planar monopole antenna is presented. The impedance and radiation characteristics of the monopole with different holes and feed gaps are experimentally examined. The measured results demonstrate that the proposed antenna is capable of providing significantly broad impedance bandwidth with acceptable radiation performance.
