A Loop-based Microstrip Dipole Antenna for Operations at 1 GHz
Abstract
This paper proposes, designs, simulates, and analyses a novel microstrip dipole antenna design consisting of two identical loops for operations for a bandwidth centering around 1 GHz (namely the 0.5 GHz to 1.5 GHz bandwidth). This proposed design consisted of FR-4 being used as a substrate of a thickness of 1.6 mm and pure copper layers of 0.1 mm in height. It should be noted that this antenna design consisted of a coaxial feed line made of pure copper. Additionally, this circular dipole design was compared against a standard half-wavelength dipole microstrip antenna with similar parameters as the antenna proposed in this paper. Realization, simulations, and analyses were conducted using with CST Microwave Studio (an electromagnetic simulation software developed by Simulia, a subdivision of Dassault Systèmes). The proposed loop dipole antennas exhibited better values when simulated for the required bandwidth (0.5 GHz to 1.5 GHz) when compared to a standard microstrip half-wavelength dipole antenna. Additionally, the size (dimensions) of the proposed design is less “clunky” when compared to its standardized counterpart.References
