Abstract: In a metal membrane for a low-temperature-fluid storage tank wherein longitudinal and transverse corrugations are formed and both corrugations intersect each other, a bidirectional expandable member connected to each corrugation is formed in the intersection of the corrugations so that the bidirectional expandable member is longitudinally and transversely expandable. The bidirectional expandable member is protruded and is shaped like a pyramid, a dome or a cross. Each metal membrane is welded into a unit panel and the edge of each metal membrane is welded with the common edge of another adjacent metal membrane.

Abstract: An antenna system and method utilize a splitter electrically connectable to a single antenna for splitting an RF signal into two signals. A variable phase shifter shifts the phase of one of the signals. A combiner combines the phase shifted and non-phase shifted signals to produce a conditioned signal. A quality examiner circuit changes the amount of phase shift provided by the variable phase shifter to produce a plurality of different conditioned signals. The quality examiner circuit then determines a quality of each conditioned signal and changes the phase shift again to provide the highest quality conditioned signal to a receiver.

Abstract: An antenna system for receiving an RF signal from a first antenna and a second antenna includes a phase shift circuit. The phase shift circuit shifts a phase of the RF signal from the second antenna by one of a plurality of possible phase shifts to produce a phase shifted signal. A combiner combines the RF signal from the first antenna and the phase shifted signal to produce a combined signal. A comparator circuit compares a signal quality of the combined signal with a minimum threshold value to determine if the signal quality of the combined signal is equal to or greater than the threshold value. The comparator circuit is in communicative control of the phase shift circuit and maintains the phase shift of the RF signal received by the second antenna in response to the signal quality of the combined signal being equal to or greater than the threshold value.

Abstract: An antenna system (10) for receiving satellite signals in a vehicle exhibits a radiation pattern (11). The antenna system (10) includes a plurality of parasitic elements (18) which are electrically connectable together using linking switches (20). The geometry of the radiation pattern (11) changes as the linking switches (20) are activated and deactivated. Control of the linking switches (20), and thus the geometry of the radiation pattern (11), is based on the geographic location of the antenna system (10). Thus, the radiation pattern (10) can be steered based on geographic location to enhance signal reception. The geographic location may be obtained automatically via a GPS receiver (30) or manually via a user.

A plurality of feed lines feed the radiating element at a plurality of feed points. The feed points are spaced apart to generate a circularly polarized radiation beam solely in a higher order mode at a desired frequency. The antenna may include a plurality of parasitic structures.

Thus, the patch antenna provides excellent RF signal reception from satellites at low elevation angles.
