Abstract

We propose the ultra-wideband antipodal bowtie antenna with staircase steps at the corners of the antipodal bowtie patch with a rounded edge and a reflector is placed at the bottom part of the antenna. The modified design of the bowtie antenna of a step cut is made to improve the bandwidth. Furthermore, in the bottom side of an antenna, the reflector is united with the feed to improve the gain. This antenna operates over for the frequency between 3.1 to 10.6 GHz, with a directive radiation pattern of peak gain 4.29 dB with the bandwidth of 3.17 GHz. This improvement in the bandwidth, gain and directional type of radiation pattern results the proposed antenna is suitable for microwave imaging applications on the early detection of breast cancer and brain tumor.
