1 Using on-board multiple beam antenna (MBA) to obtain the direction of arrival (DOA) is a new method for communication satellite interference location.

2 Using a directive beam antenna and the Highband Networking Waveform (HNW), the radio can automatically create the entire network using a single frequency.

3 The inspection method of cosecant beam antenna is discussed in depth in this paper.

4 In this paper, principle, design and test result of MMW wide beam antenna on flight vehicle is introduced.

5 The paper describes a kind of circular polarization feed, which is used for shaped beam antenna.
