Abstract:
A multi-layer microwave corrugated printed circuit board is provided. In one embodiment, an interconnect assembly includes a first flat flexible layer having a signal conductor and a ground conductor forming a first microstripline or microstrip transmission line, a second folded flexible layer having a signal conductor and a ground conductor forming a second microstripline or microstrip transmission line, the bottom surface of the second folded flexible layer having ridge portions, a non-conductive adhesive layer disposed between the top surface of the first flat flexible layer and the ridge portions of the second folded flexible layer, a signal through-hole extending through the non-conductive adhesive layer and the first flat flexible layer, and two ground through-holes extending through the non-conductive adhesive layer and the second folded flexible layer, wherein the two ground through-holes are disposed on opposite sides of the signal through-hole.
Abstract:
A coincident phased dual-polarized antenna array configured to emit electromagnetic radiation includes: a plurality of electromagnetic radiators arranged in a grid, the plurality of electromagnetic radiators defining a plurality of notches; a ground plane spaced from the electromagnetic radiators; a conductive layer disposed between the electromagnetic radiators and the ground plane, the conductive layer having a plurality of slots laterally offset from the notches and being spaced apart from and electrically insulated from the electromagnetic radiators; and a plurality of feeds, each of the feeds spanning a corresponding slot of the slots and electrically connected to a portion of the conductive layer at one side of the corresponding slot.
Abstract:
A system and method for processing antenna signals are provided. For example, the method includes, in a receive mode, weighting and combining signals from at least one low-band antenna radiator element operable over a first bandwidth, at least one high-band antenna radiator element operable over a second bandwidth at least partially overlapping the first bandwidth, and, in some examples, at least one antenna radiator element operable over one or more intermediate bandwidths. The method also includes, in a transmit mode, separating and weighting a full-band input port signal into at least one low-band sub-system output port signal, at least one high-band sub-system port output signal, and, in some examples, at least one intermediate sub-system output port signal operable over one or more overlapping intermediate bandwidths. The weighted combination and weighted separation cover an uninterrupted continuous full-band frequency whose extent covers the full frequency range of all subbands.
