Abstract

Based on a framework recently published, the double-Cornu spiral antenna is extended to an array to enhance the gain. The designed array of 2×2-elements is of low profile and small sizes, has however a large effective bandwidth, and shows overall good radiation characteristics: enhanced gain, large axial ratio bandwidth, and high degree of polarization purity. Except for a few deviations, which are due to manufacturing tolerances, artificial noise and measurement uncertainties on the one hand and diffracted waves at external edges on the other, simulated results and experimental data fit well together. In addition, EMC along with signal integrity issues related to the reduction of noise and unwanted radiation have been addressed. The proposed antenna is suitable for 5G applications and radar systems. With 14.02 dB realized gain, 6.2 GHz effective bandwidth and an uplink data rate of 3.44 Mbit/s, the array is promising for many mobility applications.
