摘要： Antenna structures are provided which facilitate the simultaneous radiation of multiple antenna beams. The structures include photonic manifolds that define equal-length optical paths and other optical paths whose lengths progressively change by a selected length .DELTA.L. The manifolds conduct signal pairs to radiative modules. Each signal pair includes a frequency-swept scanning signal s.sub.s and a reference signal s.sub.r whose frequency is a selected one of the sum and the difference of the frequencies of the scanning signal s.sub.s and a respective operating signal s.sub.o. Subsequently, the scanning signals are mixed with the reference signals and filtered to recover phase-shifted versions of each respective operating signal s.sub.o. The phase-shifted versions are radiated to form multiple radiated beams wherein each beam is scanned by changing the frequency of its respective scanning signal s.sub.s. The frequency of the scanning signals is selected to avoid generation of spurious radiated signals. This selection includes choosing the scanning signals so that each has a different integer number of 2.pi. phase shifts over the path length .DELTA.L. Methods of the invention permit the use of a common mixer and a common filter at each radiative module for processing all signal pairs.

摘要： Wideband phased array antennas are provided that eliminate the need for phase shifters in the region of the array face. In addition, they generate less beam squint than conventional antennas. In one embodiment, they include an electronic signal generator, reference and scanning manifolds and an array of n radiative modules. The signal generator generates a variable-frequency scanning signal s.sub.s and a reference signal s.sub.r wherein the frequency of the reference signal s.sub.r is substantially a selected one of the sum and the difference of the frequencies of the scanning signal s.sub.s and an operating signal s.sub.o. The reference manifold receives and divides the reference signal s.sub.r into n reference signal samples which are progressively time delayed by a selectable one of m reference differential time delays .DELTA.t.sub.r. The scanning manifold receives and divides the scanning signal s.sub.o into n scanning signal samples which are progressively time delayed by a scanning differential time delay .DELTA.t.sub.s. Each of the radiative modules includes a mixing device, an electromagnetic radiator and a filter. The mixing device receives and mixes a respective one of the reference signal samples and a respective one of the scanning signal samples. The filter couples the mixing device to the radiator and is configured to pass the operating signal s.sub.o. Accordingly, an antenna beam is radiated from the array at m selectable scan angles with each of the scan angles varying in response to the frequency of the scanning signal s.sub.s. Multiband and two-dimensional embodiments are shown and described. The wideband characteristics of these antennas are especially suited for radar, electronic warfare and high data-rate communication applications.

摘要： A multilayer switching assembly for switching high frequency signals has MEMS structures on a ceramic substrate having a top surface, a bottom surface and a plurality of insulating layers. The insulating layers are separated by a first conductor and a second conductor. The first conductor is connected to a ground potential. The second conductor is separated from the first conductor by one of the insulating layers. The second conductor presents a specific impedance (50 ohms) with respect to the first conductor to high frequency signals traveling on the second conductor.64 MEMS structures are mounted on the top surface. Each MEMS has an input, an output, and a control. The input connected to the second conductor. The output is connected to a coplanar waveguide placed on the top surface. The control is connected to the bottom surface.The input to each MEMS is electrically shielded from the output and from the control by a third conductor connected to the first (grounded) conductor. The third conductor traverses one or more of the insulating layers thereby acting as a shield and precluding the high frequency signals presented to the input from propagating to the output and to the control. The 64 MEMS are arranged in a square 8 by 8 matrix, as well as their controls. High frequency inputs and outputs to be switched by the MEMS are placed on the periphery of the substrate to further enhance the separation of signals. Terminating resistors (50 ohms) are also placed near the periphery.

摘要： A transmission line-to-waveguide transition that includes a microstrip impedance transformer for matching the impedance of an input transmission line to that of a flared slotline is disclosed. The slotline's width is sufficiently small such that when the transition is inserted into a waveguide the slotline is spaced inward from the waveguide's inner walls. A balun bi-directionally couples the unbalanced signal on the microstrip to a balanced signal on the slotline. The signal propagates along the slotline and is capacitively coupled to the waveguide. A trimmable tuning stub is used to adjust the resonant frequency of a parasitic cavity formed between the transition and the waveguide to increase the transition's effective bandwidth. A tapered dielectric insert is positioned inside the waveguide to decrease its size and to improve the coupling efficiency of the transition.

摘要： A calibration and diagnostic system and method for evaluating the performance of a wide band array utilizing a true-time-delay beamforming network. A short pulse typically on the order of a 2 nanoseconds is synthesized by transmission of a large number of discrete, equally spaced frequencies over the bandwidth over a short period of time, during which the system response (amplitude and phase) is measured and stored in a computer. The collected data is then transformed into the time domain to demonstrate the range resolution of the system. By signal injection with a built-in calibration system, the setting of each programmable delay line of the array can be calibrated. A fiber-optic test set is used as a transponder in the far field to perform complete end-to-end tests of the array system.

The first and second patch plates are coplanar and separated by a radiating slot. An excitation probe isolatedly passes through the ground plane and connects to the first patch plate. A first wall connects an edge of the first patch plate to the ground plane. The first wall is located approximately ¼ wavelength of a mid-band operating frequency from the radiating slot. A second wall connects an edge of the second patch plate to the ground plane. The second wall is located approximately ¼ wavelength of the mid-band operating frequency from the radiating slot.
