Abstract: Disclosed are a method, apparatus, system and terminal device for measuring the total radiated power of an array antenna, and a non-transitory computer-readable storage medium. The method includes: dividing an array antenna to be measured into N antenna sub-arrays, the N being greater than or equal to 2; determining a sampling interval according to the sizes of the N antenna sub-arrays; determining sampling points according to the sampling interval; and determining the total radiated power of the entire array antenna according to the equivalent isotropic radiated power of the sampling points.

Abstract: Provided are a method, apparatus and system for measuring total radiated power of an array antenna. The method includes: determining a Rayleigh resolution of the array antenna in an angle space, and setting a stepping grid spacing of sampling points according to the Rayleigh resolution; determining the sampling points according to the stepping grid spacing, measuring equivalent isotropic radiated power (EIRP) at positions of the sampling points and determining the TRP according to the EIRP. Compared with a traditional rest mode using an angle stepping grid θgrid and φgrid of 15°, this reduces measurement errors; and additionally, through a normalized wave vector space transformation, the number of sampling points is further reduced, and the measurement efficiency is improved.

Abstract: Provided are a coupling device, a surface wave coupling method, and an open wire surface wave wireless coverage system. The coupling device comprises: a high-order mode direct coupling module configured to couple a first electromagnetic wave from a transmitter to form a second electromagnetic wave propagating in a preset high-order guided wave mode; a mode converting and filtering module configured to convert the second electromagnetic wave into a third electromagnetic wave propagating in a superposition of a plurality of guided wave modes, and to filter the high-order guided wave mode in the third electromagnetic wave to obtain a fourth electromagnetic wave propagating in the preset low-order guided wave mode; and a mode matching module configured to convert the fourth electromagnetic wave into a fifth electromagnetic wave propagating along a surface of an open wire in a target guided wave mode.
