Abstract

The effect of corrugation parameters of a corrugated plate monopole antenna in terms of lower edge frequency, impedance bandwidth, and radiation properties, was investigated. The corrugated plate monopole was constructed using a planar sheet of 0.2-mm-thick brass and fed through a groundplane using an SMA feedprobe. The return loss for the simple planar monopole dimension of 40 × 40 planar with 2-mm feedgap was measured and found to be greater than 10dB in the range 1.54-2.96 GHz. The results show that the lower-edge frequency of the impedance bandwidth can be reduced by up to 36% by corrugating the plate monopole, at the expense of impedance bandwidth.
