Uniden Scanner Antenna

The first complete guide to phased array design and theory in more than thirty years destined to become the standard reference in the field well into the twenty-first century The past twenty years have witnessed significant breakthroughs in our understanding of the principles behind phased array antennas and in their design and application. Yet not since R. C. Hansen's 1966 classic, Microwave Scanning Antennas, has there been a comprehensive reference in the field. Phased Array Antennas fills the gap in the professional literature. Phased Array Antennas is geared to the interests of both the practicing design engineer and the antenna array analyst. Written by an internationally recognized expert with more than four decades of experience in the field, it offers detailed coverage of all practical and theoretical aspects of phased arrays from quantization lobes and low sidelobe pattern design and measurement to superdirectivity and HTS antennas and frequency scanners. It also provides in-depth coverage of topics such as finite array Gibbsian models, photonic feeding and time delay, waveguide simulators, and beam orthogonality. A multitude of original curves and tables show particular behaviors derived from hundreds of programs developed by the author over the past twenty years, and numerous computer design algorithms and numerical tips are found throughout the book. Phased Array Antennas is an indispensable tool-of-the-trade for antenna design engineers, radar engineers, PCS engineers, and communications engineers. It also serves as a complete text in phased array design and theory for advanced undergraduate-and graduate-level courses in electronics and communications.

Motorola connector - A common coaxial cable connector used primarily in the automotive industry for connecting the coaxial feedline from the antenna to the radio receiver. It is also sometimes used for connecting scanner antennas to scanners.

Periscope antenna - In telecommunication, a periscope antenna is an antenna configuration in which the transmitting antenna is oriented to produce a vertical radiation pattern, and a flat or off-axis parabolic reflector, mounted above the transmitting antenna, is used to direct the beam in a horizontal path toward the receiving antenna.

Microstrip antenna - In telecommunication, There are several types of microstrip antennas (also known as a printed antennas) the most common of which is the microstrip patch antenna or patch antenna. A patch antenna is a narrowband, wide-beam antenna fabricated by etching the antenna element pattern in metal trace bonded to an insulating substrate.

Image antenna - In telecommunication, an image antenna is a hypothetical mirror-image, that is, a virtual-image, of an antenna, that is, antenna element, considered to extend as far below ground, that is, the ground plane, as the actual antenna is above the ground plane.
