A Modified Bow Tie Antenna With U-Shape Slot for Wireless Applications
A bow tie antenna is made from a bi-triangular sheet of FR4 substrate. A different category of antennas which can offer large bandwidths is the bi-conical antenna. Bow tie antennas, which basically are the limiting case of bi-conical antennas, are attractive mainly due to their simplicity and wideband property. Bow tie antenna is actually a flat version of bi-conical dipole antenna. These antennas have many advantages such as low fabrication cost, high radiation efficiency, ease of manufacturing & low profile.
