Fig. 2From: A flower bud-shaped flexible UWB antenna for healthcare applicationsGeometry of flower bud-shaped hexagonal microstrip antenna (FBHMSA). The basic hexagonal-shaped patch is cut equally from the top left and right side edges of the hexagon with 1.7 mm that has resulted in the patch being into the shape of the flower bud as shown in a. Also, as presented in b, two cuts of the size \(3\,{\text{mm}} \times 4\,{\text{mm}}\) at the left and right corners of the partial ground are introduced which made good enhancement in the bandwidth as well as gain of the antenna. a, b represent the top view and back view of the proposed antennaBack to article page
