Figure 1: Typical Bowtie Antenna

Figure 1 shows a typical Bowtie Antenna. Due to its distinctive shape, it’s often referred to as a butterfly antenna.

There are several variations of Bowtie antennas, including:

• Wideband Printed Bowtie antenna
• Bowtie slot antenna
• Double-sided triangular Bowtie antenna
• Bowtie antenna microstrip fed
• Slotted Bowtie patch antenna
• CPW fed curved bow tie slot antenna
