Square planar monopole antenna [PDF]
IEE National Conference on Antennas and Propagation, 1999 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.
