This paper presents FEKO simulations done on three dipole like structures; the Big Blade, the Tied-Fork and the Fork antenna. These antenna elements are considered for the design of the Long Wavelength Array (LWA). The LWA is an interferometer under construction in New Mexico, USA for astronomical observations in the 20 - 80 MHz spectrum. This paper presents the simulation results of antenna gains, impedance values, and mutual couplings for each candidate elements.
