Abstract :
This paper presents the design and simulation of a broadband microstrip spiral antenna incorporated with chip resistors embedded in the substrate. A single arm version of an equiangular spiral antenna is investigated. The effect of strategically loading the spiral with chip resistors is explored in terms of the simulated return loss, gain, axial ratio and radiation pattern.
