Performance and design of spear shaped antenna for UWB band applications

Abstract

This paper presents a novel design of a spear shaped antenna for wireless communications. Presently many research groups are working on wireless communication technologies and proposed various types of antenna designs. This proposed antenna fulfills the requirement of low cost, less weight, small size for wireless devices. The design and simulation of proposed CPW fed antenna are carried out with RT Duroid substrate and dimension of antenna substrate is 14 mm × 18 mm. The operating frequency of the proposed antenna is 3.1–10.8 GHz. High Frequency Structure Simulator software HFSS's optometric is used for the proposed antenna for more accuracy and results are optimized. The simple configuration and low profile attributes of the proposed antenna made it easy for fabrication and suitable for the application in the UWB band applications.
