DUAL BAND ANTENNA CONFIGURATION

摘要

A dual band antenna configuration constituted of: a waveguide extending from a proximal section to a high frequency band section; a first high frequency band port extending from the high frequency band section of the waveguide; a first low frequency band port extending, from an outer surface of a low frequency section of the waveguide, along a first radial path; a second low frequency band port extending, from the outer surface of the low frequency section of the waveguide, along a second radial path, the second radial path orthogonal to the first radial path; and a 180 degree hybrid coupler, wherein a first port of the 180 degree hybrid coupler in electrical communication with the first low frequency band port and a second port of the 180 degree hybrid coupler, different than the first port thereof, in electrical communication with the second low frequency band port.
