摘要： An antenna includes a reference potential layer, a feed element, a parasitic element, and at least one connecting conductor. The reference potential layer extends in a first direction and a second direction orthogonal to the first direction. The feed element is composed of a layered conductor facing the reference potential layer. Further, the feed element has a first feed point at a position toward one side in the first direction relative to a center of the feed element in the first direction. The parasitic element is composed of a layered conductor facing the feed element from a side opposite the reference potential layer. The connecting conductor is connected to the feed element and the parasitic element at a position closer to the center of the feed element than the first feed point in first direction, and is not electrically connected to the reference potential layer.

摘要： Global navigation satellite system (GNSS) radio frequency signals broadcast from geo-stationary satellites 20,000 km above the earth when received by GNSS receivers are fundamentally weak. Accordingly, these GNSS receivers are vulnerable to accidental and deliberate interference from a range of synthetic sources as well as natural sources. Existing anti-jamming technologies such as controlled reception pattern antennas, adaptive antennas, null-steering antennas, and beamforming antennas etc. are expensive and incompatible with many lower cost and footprint limited applications. However, in many applications the GNSS antenna is mounted upon a fixed or mobile element such that accidental and intentional jammers tend to be in the plane of the antenna or below it. Accordingly, there are presented designs and techniques to improve the anti-jamming or interference performance of GNSS receivers by further reducing the responsivity of the GNSS receiver to signals in-plane or below the plane of the antenna.

摘要： A technique is described where the switch and/or tunable control circuit for use with an active multi-mode antenna is positioned remote from the antenna structure itself for integration into host communication systems. Electrical delay and impedance characteristics are compensated for in the design and configuration of transmission lines or parasitic elements as the active multi-mode antenna structure is positioned in optimal locations such that significant electrical delay is introduced between the RF front-end circuit and multi-mode antenna. This technique can be implemented in designs where it is convenient to locate switches in a front-end module (FEM) and the FEM is located in vicinity to the transceiver.
