Title: MICROWAVE/MILLIMETER-WAVE DUAL-BAND ANTENNA
Abstract:
Provided is a microwave/millimeter-wave dual-band antenna. The antenna comprises: multiple dual-band subarray antennas arranged circularly to form a regular polygonal column; and a millimeter-wave power-feeding network and a microwave power-feeding network positioned respectively at two side surfaces of the regular polygonal column, wherein each dual-band subarray antenna comprises: a metal plate, a second dielectric layer superimposing the metal plate, a millimeter-wave radiation array, a first dielectric layer, and a microwave radiation array, the microwave radiation array is connected to the microwave power-feeding network, and the millimeter-wave radiation array is connected to the millimeter-wave power-feeding network. Using the millimeter-wave radiation array and the microwave radiation array enhances band selection of an antenna and expands operating bands of the antenna.
