Abstract
A phase shifter device is disclosed and comprises a continuous transmission line on a substrate, and a plurality of ports coupled to the continuous transmission line and spaced apart from each other around the continuous transmission line. The plurality of ports comprises a first port, a second port, a third port, a fourth port, and a fifth port. A radio frequency (RF) switch is operative to connect either the first port or the fifth port to a main RF line that is coupled to one or more antennas. The second port is located between the first port and the third port, and the fourth port is located between the fifth port and the third port. In an alternative embodiment, the phase shifter device is combined with a circular polarization quadrature divider.

A phase shifter device, comprising:
- a continuous transmission line on a substrate;
- a plurality of ports coupled to the continuous transmission line and spaced apart from each other around the continuous transmission line, the plurality of ports comprising a first port, a second port, a third port, a fourth port, and a fifth port;
- and
- a radio frequency (RF) switch operative to connect either the first port or the fifth port to a main RF line that is coupled to one or more antennas;
- wherein the second port is located between the first port and the third port, and the fourth port is located between the fifth port and the third port.
A combined device, comprising:
- a phase shifter portion comprising:
- a continuous transmission line on a substrate;
- and
- a plurality of ports coupled to the continuous transmission line and spaced apart from each other around the continuous transmission line, the plurality of ports comprising a first port, a second port, a third port, a fourth port, and a fifth port;
- wherein a portion of the continuous transmission line, between the first port and the fifth port, has a compact meandering-shaped arrangement, the portion of the continuous transmission line located within a perimeter defined by a remainder of the continuous transmission line;
- wherein the continuous transmission line is arranged such that the first port and the fifth port are located adjacent to each other;
- a circular polarization (CP) quadrature divider portion coupled to the continuous transmission line, the CP quadrature divider located within the perimeter defined by the remainder of the continuous transmission line, the CP quadrature divider portion comprising:
- a first section coupled to the second port, the first section including a first transmission line segment and a second transmission line segment;
- and
- a second section coupled to the fourth port, the second section including a first transmission line segment and a second transmission line segment;
- wherein the first and second sections have a compact meandering-shaped arrangement;
- and
- a radio frequency (RF) switch operative to connect either the first port or the fifth port to a main RF line that is coupled to a phased array antenna.
