An axial mode helical antenna consists of conducting wire wound in the form of a helix mounted on a reflector is to be proposed. Metal helical antenna (MHA) has typical advantages, such as directivity and circular polarization, and is widely used in directional wireless communication system, as well as in the satellite system [1]. Helical antenna has been widely used as simple and practical radiators over the last five decades due to their remarkable and unique properties [2-3]. The rigorous analysis of a helix is extremely complicated. Therefore, radiation properties of the helix, such as...

Biologics have revolutionized the treatment of autoimmune diseases due to their efficacy, speed of onset, and tolerability. The development of new agents and expanded use of existing agents continues to be a highly active area of investigation among rheumatic diseases, with a multitude of innovative therapeutic strategies in various stages of development. Although the story of treatments continues rapidly, therapeutic research in some conditions is hindered by the rarity of the disease, variation in phenotype, and concerns about toxicity. This fast-paced development of...
