Abstract
The antenna under study is an extended version of a cylindrical waveguide-based leaky-wave antenna. A cylindrical waveguide is attached to a spherical cavity on one end. The radiating slot in the form of a cylindrical disk is placed at the center of the cavity to achieve the leaky wave characteristics. The combined structure resembles the shape of a mic. The unique characteristics of this shape enable the antenna to radiate in four different directions there by producing a cross-shaped radiation pattern. Novel design exploits the advantages offered by the material body through analysis to maximize the antenna features such as gain, return loss and polarization. The antenna presented in the current literature operates at 90GHz with a moderate gain of 8.7dB in the downward direction, 4.9dB in the upward direction and 3.45dB towards the sides.
