## Abstract

A phase shifting device, including: a housing; and at least one multipath phase shifter assembly in the housing, wherein the multipath phase shifter assembly includes at least two phase shifters disposed in parallel in a planar arrangement.

## Claims

### Claim 1

A phase shifting device, comprising:
a housing; and
at least one multipath phase shifter assembly in the housing, wherein the multipath phase shifter assembly includes at least two phase shifters disposed in parallel in a planar arrangement.

### Claim 2 (depends on 1)
