Dual-Band Antenna with Pattern and Polarization Diversity. [PDF]

open access: yesSensors (Basel)
In this letter, we propose a pattern-diversity antenna with different radiation patterns at two different frequency bands (f1 and f2) (f1: broadside radiation pattern, f2: conical radiation pattern). The proposed structure consists of a central circular antenna and two annular ring antennas; each of the three antennas has individual ports.
