A novel broadband antenna, the low profile dipole planar inverted cone antenna (LPdiPICA)

A new broadband dipole teardrop antenna, the LPdiPICA (low profile dipole planar inverted cone antenna), is proposed for wireless communication applications. The antenna element has the shape of dual teardrops printed on a dielectric material. The element is backed with a finite ground plane for a high gain unidirectional pattern. The antenna is linearly polarized and provides more than 10:1 impedance bandwidth and 2.2:1 pattern bandwidth. The HPBW (half power beam width) of the antenna is 50°-60° and 70°-90° in the E- and H-planes, respectively, and a maximum gain of 6-10 dBi over the bandwidth. The dipole teardrop antenna is modeled as made up of wire and tapered slot antenna components that operate in the lower and upper bands, respectively.
