Abstract: An antenna system includes an antenna structure and an antenna interface. The antenna structure includes ‘x’ number of spiral antenna sections. Each spiral antenna section transmits a different phase of ‘x’ phases of an outbound RF signal and receives a different phase of ‘x’ phases of an inbound RF signal. The antenna interface generates the ‘x’ phases of the outbound RF signal by splitting the outbound RF signal into ‘x’ copies and phase shifting each of the ‘x’ copies. The antenna interface also combines the ‘x’ phases of the inbound RF signal to produce the inbound RF signal by phase shifting each of the ‘x’ phases of the inbound RF signal by the respective phase shift and combining the ‘x’ copies.

Abstract: An RF transceiver front-end includes receiver and transmitter front-ends. The receiver front-end includes 1st and 2nd antennas, a ninety degree phase shift module and an LNA module. The 1st and 2nd antennas receive inbound RF signals and provide a first directional circular polarization. The ninety degree phase shift module phase shifts the RF signals received by the 2nd antenna. The LNA module amplifies the RF signals received by the 1st antenna and the shifted RF signals. The transmitter front-end includes a PA module and 3rd and 4th antennas, which provide a second directional circular polarization. The PA module amplifies outbound RF signals to produce amplified outbound RF signals and amplified orthogonal outbound RF signals. The 3rd antenna transmits the amplified outbound RF signals and the 4th antenna transmits the amplified orthogonal outbound RF signals.

Abstract: A bidirectional time-division duplexing transceiver circuit includes a first and a second bidirectional phase-shift circuit, and a bidirectional amplifier circuit including a first amplifier circuit and a second amplifier circuit. The first amplifier circuit and the second amplifier circuit are coupled via double-pole-double-throw (DPDT) switches to radio-frequency (RF) antennas and the first and the second bidirectional phase-shift circuits. The (DPDT) switches enable the first amplifier circuit and the second amplifier circuit to be operable simultaneously as transmit (TX) path amplifiers in a first time slot and as a receive (RX) path amplifiers in a second time slot.

Abstract: A three-dimensional multiple spiral antenna includes a substrate, a plurality of spiral antenna sections, and a feed point module. The substrate has a three-dimensional shaped region and each spiral antenna section is supported by a corresponding section of the three-dimensional shaped region and conforms to the corresponding section of the three-dimensional shaped region such that, collectively, the spiral antenna sections have an overall shape approximating a three-dimensional shape. The feed point module is coupled to a connection point of at least one of the spiral antenna sections.

Abstract: An antenna assembly a spiral antenna feed and a programmable circuit. The spiral antenna feed includes a substrate, a spiral antenna element, and a feed point. The substrate has a three-dimensional hyperbolic shaped region, which supports the spiral antenna element such that the spiral antenna element has an overall shape approximating a three-dimensional hyperbolic shape. The feed point is coupled to a connection point of the spiral antenna element. The programmable circuit produces a projected artificial magnetic conductor reflector dish that reflects an inbound RF signal to the spiral antenna feed and reflects an outbound RF signal from the spiral antenna feed.
