A dual-polarized antenna, and an associated methodology, is provided for a radio device, such as a mobile station. The antenna is formed of a plurality of patches configured into an array, symmetrical in both a first polarization direction and a second polarization direction. Adjacent patches of the array are interconnected by connecting strips that are also symmetrically positioned in the two directions. These connecting strips not only act as feeding lines for the patches but also operate as in-phase radiation elements in each polarization direction. A transverse strip extends between a pair of transversely positioned patches. And a single feed connection is provided thereat.

The invention discloses a dual-polarized antenna with high isolation and low profile applied to WLAN, which is composed of a single-sided microstrip circuit board and a grounding structure board with a rectangular air back cavity, which expands the working bandwidth of the antenna while maintaining The structural advantages and radiation performance of the single-layer microstrip antenna, using the innovative structure of a single-layer microstrip plus a back cavity, is designed with a simple structure, low profile, and easy integration with the feed network design. Advantages, it is easy to realize a microstrip patch antenna array with high efficiency and low profile.

The invention provides an active phased array antenna unit-level inner monitoring device. The active phased array antenna unit-level inner monitoring device comprises a microstrip patch antenna array,a coupling feeder line, an equal-power-dividing power divider, an absorption resistor, a microwave dielectric substrate and a radio frequency monitoring port. The microstrip patch antenna array unitcan adopt any patch form, and the array can adopt any array arrangement mode; the absorption resistor is connected to one end of the coupling feeder line, and the other end is used for performing cascading on the coupling feeder lines through the equal-power-dividing power divider; the length of the coupling feeder line can be adjusted according to actual design requirements, and the microstrip patch antenna array units of any numbers can be covered; and the microstrip patch antenna array, the coupling feeder line and the equal-power-division power divider are all printed on the single-layer microwave dielectric substrate. The microstrip patch antenna array and the monitoring module are integrated, so that the quantity of equipment and the number of cables can be reduced, and compared withthe conventional monitoring module which adopts a multilayer lamination or multilayer board penetration interconnection technology, the monitoring module of the invention is easy to machine and implement, and has the characteristics of being low in cost, high in reliability, high in integration level and convenient to manufacture and assemble.
