摘要： A reconfigurable holographic antenna and a method of shaping an antenna beam pattern of a reconfigurable holographic antenna is disclosed. A baseline holographic pattern is driven onto a reconfigurable layer of the reconfigurable holographic antenna while a feed wave excites the reconfigurable layer. An antenna pattern metric representative of a baseline antenna pattern is received. The baseline antenna pattern is generated by the reconfigurable holographic antenna while the baseline holographic pattern is driven onto the reconfigurable layer. A modified holographic pattern is generated in response to the antenna pattern metric. The modified holographic pattern is driven onto the reconfigurable layer of the reconfigurable holographic antenna to generate an improved antenna pattern.

摘要： Techniques and mechanisms to transmit signals with an antenna array. In an embodiment, a first signal is received at a first input of the first antenna while a second signal is received at a second input of the second antenna. A difference in phase differentials—the phase differentials each between the first signal and the second signal—results from propagation of the first signal and the second signal in the antenna array and from a difference between respective configurations of the first antenna and the second antenna. Each of the first antenna and the second antenna has respective emitters distributed along the length thereof. In another embodiment, the first antenna and the second antenna have different respective dielectric structures or different respective distributions of emitters.

摘要： A method and apparatus is disclosed herein for acquiring and tracking a satellite signal with an antenna. In one embodiment, the method comprises a) perturbing one or more of roll, pitch and yaw angles of an antenna orientation to create variant orientations associated with a first search pattern; b) computing new scan and polarization angles, in response to perturbed roll, pitch and yaw angles, for each of the variant orientations; c) receiving a radio-frequency (RF) signal from a satellite for each of the variant orientations; d) generating one or more receiver metrics representing a received RF signal associated with each of the variant orientations; e) selecting, as a new orientation, one of the variant orientations based on the one or more receiver metrics; and f) repeating a)-e) with the new orientation with a second search pattern narrower than the first search pattern.
