Wideband sub-6 GHz self-grounded bow-tie antenna with new feeding mechanism for 5G communication systems

This paper presents a self-grounded directional Bow-Tie antenna with a novel feed structure for sub-6 GHz applications in 5G communication systems covering 3.35-4.4. The antenna consists of two petal shaped metal structures that are interconnected to each other with a microstrip line. The petals are anchored on a common ground-plane. The feed mechanism used to excite the petals is by EM coupling from a single open-circuited microstrip line implemented behind the ground-plane. The couples EM energy is controlled via an I-shaped slot printed on the ground-plane. The proposed antenna offers good impedance matching across its operating frequency range with VSWR
