Application of new concentrated radiation-feed network in DC system transformer substation;

On the basis of the radar production experience and manufacture practice, this paper shows that the moulding of the feed network is feasible through comparison of several methods and examination of a lot of experiments, especially for E/H dimension curved waveguide component.

A feed network design method of wind-profile radar phased array is introduced in this paper.

Ternary helix antenna array combing with stripline feeding network which is shortest in axial direction was used to achieve communication between the satellites of Inmarsat and ships.

This paper describes the composition of an L - band traveling wave feeding network,and focuses on the design and implementation of its critical component—directional coupler.

The air stripline feeding network is featured with low loss,high power capacitance,and it is easy to control its amplitude and phase.

It is composed of that: the design of the element of the antenna, the design of the feeding circuit network, the design of the array of the antenna, and the study of the beam controlled.

This paper primary introduces the design of the antenna and its feeding circuit network which is used in the elevation plane of the MLS.

Y shape microwave network and its application to radar system;

Based on the technological analysis of microwave network devices,the technological process and parameters for turning this kind of parts are determined on the premise of meeting the performance requirements,thus,a practical technological process is established for machining and manufacturing this kind of parts.

The paper briefly introduces the principle of enhanced electronic calibration, the concept and application of mixed mode S parameters in modern microwave network analysis, and the method of accurate high power measurements by vector network analyzers.
