Disclosed is a beam steering antenna structure, including two parallel metallic boards, an antenna perpendicularly disposed between the two metallic boards, a plurality of substrates perpendicularly disposed between the two metallic boards and radially disposed around the antenna, and a bias voltage circuit. Each of the substrates has a plurality of metal units cyclically aligned thereon, and each of the metal units includes two metallic regions oppositely disposed and in no contact with each other and a transistor disposed between the two metallic regions for coupling the two metallic regions. The transistors are electrically connected to the bias voltage circuit to thereby control the steering direction of beam radiation by switching the transistors.

A comparator of a mono-pulse radar and a signal generation method thereof are provided. The comparator includes an antenna array, a TEM mode cavity power combiner and a switch device. The antenna array includes N antennas. The TEM mode cavity power combiner includes a combination port and M input port sets, and each of the input port sets has a positive input port and a negative input port, wherein N and M are integer greater than 1. The switch device is coupled between the antenna array and the TEM mode cavity power combiner and is used for transmitting the reflected signal received by the antenna array to the positive input port or the negative input port of one of the input port sets. The combination port of the TEM mode cavity power combiner generates an output signal according to the reflected signals received from the input port sets.

A vertical transmission structure for high frequency transmission lines includes a conductive axial core and a conductive structure surrounding the conductive axial core. The vertical transmission structure is applied to a high-frequency flip chip package for reducing the possibility of underfill from coming in contact with the conductive axial core.
