摘要： A method and system for transmitting, and a signal comprising multiple frequency bands from a single slot antenna are disclosed. The system comprises a slot antenna and a micro-electro-mechanical (MEM) switch, coupled to the slot antenna. The MEM switch is opened and closed, thereby changing the resonant frequency of the slot antenna. The slot antenna transmits a first frequency when the MEM switch is open and a second frequency when the MEM switch is closed. The method for transmitting a first frequency and a second frequency from a slot antenna comprises the steps of transmitting the first frequency from the slot antenna, closing a micro-electro-mechanical (MEM) switch coupled across the slot antenna, therein changing the resonant frequency of the slot antenna, and transmitting the second frequency from the slot antenna after the MEM switch is closed. A signal comprising a first and second frequency in accordance with the present invention is transmitted by an array of antennas, wherein the array of antennas comprises at least one slot, the slot being reconfigurable through a RF MEM switch coupled to the slot, by performing the steps of transmitting the first frequency from the slot antenna, closing a micro-electro-mechanical (MEM) switch coupled across the slot antenna, therein changing the resonant frequency of the slot antenna, and transmitting the second frequency from the slot antenna after the MEM switch is closed.

摘要： A reconfigurable wide band phased array antenna for generating multiple antenna beams for multiple transmit and receive functions. The antenna array comprises multiple long non-resonant TEM slot antenna apertures with RF MEMS switches disposed within the slots. The RF MEMS switches are positioned directly within the feed lines across the slots to directly control the coupling of RF energy to the slots. Multiple RF MEMS switches are used within each slot, which allows multiple transmit/receive functions and/or multiple frequencies to be supported by each slot. The frequency coverage provided by the slot antenna has a greater than 10:1 frequency range.

摘要： A phased array radar system employs programmable microelectromechanical (MEM) switches and transmission lines to provide true time delays or phase shifts in order to steer the array beam. The array includes an excitation signal source, a power division network for dividing the excitation signal into a plurality of excitation signal components, a plurality of programmable time delay/phase shift circuits including the transmission lines and MEM switches, and a plurality of radiating elements. An adaptive controller provides the control signals to set the MEM switches and select the time delay/phase shift through each time delay/phase shift circuit, thereby steering the array beam to a desired direction.

摘要： A dual-patch antenna includes a ground plane, a first patch plate parallel to and separated from the ground plane by a separation distance, and a second patch plate separated from the ground plane by the separation distance. 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. The dual-patch antennas may be organized in an array.

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.

摘要： In one embodiment, a wide bandwidth, reduced depth transmit/receive antenna array includes unit cells having continuous slots, a transceiver, unbalanced feeds, impedance transformers, and exciters. The continuous slots are formed in a conductive antenna plane, and the transceiver generates and/or receives electrical signals. The unbalanced feeds may be electrically connected between the transceiver and impedance transformers which match the impedance between feed lines and the exciter. They may be located in a plane perpendicular to the direction of propagation of the radiation, and also may be arranged between the conductive antenna plane and a backplane. The exciter spans a continuous slot, and emits and/or receives radiation from the slot. The antenna array is capable of operating without a radome or balun.

摘要： A wideband end-fire array including columns or sub-arrays of flared notch radiating elements spaced along an end-fire axis and fed by a true-time-delay corporate feed network. The feed network includes a corporate feed manifold and a plurality of cables connected between a respective manifold port and a balun comprising a corresponding radiating element. The plurality of cables have corresponding electrical line lengths adapted to provide progressive time delays to signals carried between the radiating elements and the feed manifold so as to equalize the time delays due to spacing of the elements along the axis.
