Abstract

A direction-finding antenna (100) includes at least a first set of radiating elements (102A-D) configured to radiate at least a first wavelength (λ<1>) and a second set of radiating elements (104A-D) configured to radiate at a second wavelength (λ<2>) that is shorter than the first wavelength (λ<1>). The first set of radiating elements defines a first circle having a first radius. The second set of radiating elements defines a second circle having a second radius that is smaller than the first radius of the first circle. The direction-finding antenna further includes a transmission line-based multiplexer (110) configured to selectively couple the first set of radiating elements or the second set of radiating elements to a radio frequency (RF) feed line (108), or a plurality of switches (112) configured to selectively couple selected radiating elements of the first set of radiating elements or the second set of radiating elements to the RF feed line.
