A millimeter wave mobile phone antenna structure including: a plurality of antenna elements, each antenna element having a port; a plurality of signal acquisition units, each having a mixer and an analog-to-digital converter to produce a digital sampled signal of a sub-carrier signal output by each port; and a baseband signal processor, used for multiplying the digital sampled signal of each sub-carrier signal with a real time channel frequency response related weighting function and sum up the products to obtain a total output value of the antenna structure. The difference between the antenna structure of the present invention and the current millimeter-wave antenna structure of mobile phones is that: the present invention uses antenna elements instead of antenna arrays; and the antenna structure of the present invention provides multi-port output signals, rather than a single output digital, to facilitate the adaptability of received signals combining on the baseband end.

Multi-port multi-element millimeter wave mobile phone antenna structure

A millimeter wave base station antenna system having a multi-port antenna array and a baseband signal processor, the baseband signal processor having an uplink baseband processing unit for generating a first weighting function, and a downlink baseband processing unit for generating a second weighting function; the first weighting function and the second weighting function being used to enhance the desired signal and eliminate the multiuser interference.

Millimeter wave base station antenna system

It is known in the field that conventional single-port antennas cannot provide both advantages of high gain and broad angular coverage. It is also known in the field that, for modern mobile communication systems, the transmitted signals generally include not only information data, but also pilot signals, which are used for both estimating real time channel responses and facilitating signals reception. Therefore, through a proper baseband signal processing arrangement, it is possible to effectively combine sub-arrays output signals of a multi-port antenna to substantially enhance interested signals. The present invention therefore makes use of the resources provided by the pilot signals to construct a novel antenna structure having multi-port sub-arrays and a baseband signal processing function unit, to simultaneously offer the advantages of high gain and broad angular coverage. In addition, the present invention is particularly suitable for use in millimeter wavelength antennas.
