Abstract

Field-serviceable radio frequency modules can be achieved by replacing hard-wired radio frequency (RF) feedback paths with external near-field RF probes. Notably, the near-field RF probes may allow for the RF module to be installed/re-installed on a backplane or other support structure without fowling factory calibration settings. Multiple near-field RF probes can monitor a single RF module. Additionally, a single near-field RF probe can monitor multiple RF modules.

First claim

What is claimed is:

1. An active antenna device comprising:
a path;
a radiating element that radiates a wireless signal; and
a near-field radio frequency (RF) probe positioned adjacent to the radiating element such that the near-field RF probe does not obstruct a main lobe of the wireless signal radiated from the radiating element, the near-field RF probe configured to wirelessly communicate a calibration signal with the radiating element during field operation of the active…
