Design of a Blade Antenna Embedded in Low-Cost Dielectric Substrate

Abstract A design of a blade antenna embedded in low-cost dielectric substrate (FR4) and operating at 4.97 GHz is the subject of this paper. The antenna design is accomplished using parametric analysis in the HFSS™ software, where the antenna dimensions are changed and it is observed how the changes affect figures-of-merit like input impedance, reflection coefficient and radiation patterns. The antenna prototype is presented, as well as, a comparison between experimental and theoretical results.
