An antenna is an energy converter that converts traveling waves propagating on a transmission line into electromagnetic waves, radiating them into space. What is the conversion process of electromagnetic waves that we cannot see or touch?

Precision agriculture is an agricultural application and practice system, including a virtuous circle of information collection - information decoding - input optimization - field practice. Information and data are the core of precision agriculture. First, it is necessary to collect crop related information, as well as external information that aff

In recent years, the Changjiang River Farm, located in Chongming, Shanghai, has comprehensively promoted the construction of modern agricultural infrastructure, including afforestation and water conservancy, relying on the construction of 1 million mu grain field infrastructure project in Shanghai. Since the integration and application of precision

The traditional measurement methods are mostly carried out in the mode of manual+equipment+technology, so the measurement efficiency and accuracy cannot be properly guaranteed. The existing GNSS technology combines various technical advantages, integrates the operation of UAV equipment, obtains real-time and real aerial photography data, and can de

Unmanned Aerial Vehicles (UAV) are increasingly being used for a wide range of applications including reconnaissance, surveillance, surveying and mapping, spatial information acquisition and geophysics exploration, among others. Often, in these situations, GPS is the key to operating the UAV safely.

The function of the GPS receiving antenna is to convert the electromagnetic wave energy of the satellite radio signal into the current that can be absorbed and applied by the electronic equipment of the receiver.
