摘要： Techniques of designing an antenna array with antenna units controlled electronically are described. Each of the antenna units includes a reflector, a driven element and one or more directors. A substrate with conductive material on its surface provided to support the antenna array is designed to be the reflector. The driven element is separated into two halves with each on one side of a non-metal substrate vertically bonded to the conductive substrate. Two driving lines provided to drive the two halves of the driven element are disposed on both sides of the non-metal substrate to minimize possible interactions with other elements of the antenna unit or the antenna array.

摘要： A method of designing a reflectarray including a substrate having a surface perpendicular to a predetermined axis, wherein elements are disposed on the substrate. The method obtains a reflection phase of the elements as a function of a design parameter such as element spacing, when a radio wave enters the arranged elements, and stores a relationship between the reflection phase and the design parameter in a memory. Here, the design parameter is equally set for the elements. The method repeatedly determines, for each of the elements, the design parameter of a specific element in accordance with the relationship. The function of the design parameter has a range of almost 360 degrees with respect to a range of the design parameter. The reflection phase is the continuous function of the element spacing such that two resonant points occur at which the reflection phase becomes zero.

摘要： The dual scan corner reflector antenna is a frequency scanned antenna for dar, direction finding, or guidance systems which provides increased information gathering capacity over that of prior art systems. The antenna utilizes a helix frequency scanning feed to drive a dipole antenna array. Each output port of the feed is connected to a power divider or combiner to form a common line to the antenna element. At each end of the helix frequency scanning feed are hybrid terminals used to simultaneously form two receive or transmit radiation patterns. The respective helix feed couplers have symmetrical values about the center of the helix feed, allowing the two radiation patterns to be mirror images of each other at the same frequencies. These two radiation patterns can be scanned simultaneously and independently.

摘要： Provided is a rapid over-the-air (OTA) production line test platform, including a device under test (DUT), an antenna array and two reflecting plates. The DUT has a beamforming function. The antenna array is arranged opposite to the DUT, and emits beams with beamforming. Two reflecting plates are disposed opposite to each other, and are arranged between the DUT and the antenna array. The beam OTA test of the DUT is carried out by propagation of the beams between the antenna array, the DUT and the two reflecting plates. Accordingly, the test time can be greatly shortened and the cost of test can be effectively reduced. In addition to the above-mentioned rapid OTA production line test platform, platforms for performing the OTA production line test by using horn antenna arrays together with bending waveguides and using a 3D elliptic curve are also provided.
