Abstract
A novel shape of wideband conformal antenna is presented in this article. The antenna is a wideband directional conformal fork shaped antenna. A combination of the concept of tapered slot antenna and dipole arrays are used to obtain directional radiation pattern. The dipole element is formed like a fork and has a semi-annular ring structure. As a result, instead of using a wire dipole, the concept of a log periodic antenna, uses three fork-shaped dipole elements in the proposed antenna. The proposed radial cylindrical conformal antenna is operating from 3.5 to 4.1 GHz achieves an impedance bandwidth of 600 MHz. The gain of the proposed radial cylindrical conformal antenna is around 4.7 to 5.6 dBi within the operating frequency.The halfpower beamwidth HPBW at 3.3 and 3.5 GHz are 122° and 116° in the H-plane and at E-plane are 56° and 57° respectively. The proposed cylindrical antenna is a reasonable antenna for WiMAX applications.
