Multiport waveguide device

Abstract

A multiport waveguide device is disclosed herein. In an embodiment, a multiport waveguide device includes a first receiving port structure configured to guide a first incoming RF signal, a second receiving port structure configured to guide a second incoming RF signal, a first transmitting port structure configured to guide a first outgoing RF signal, and a second transmitting port structure configured to guide a second outgoing RF signal. The multiport waveguide device also includes common port structure configured to simultaneously guide the first incoming RF signal, the second incoming RF signal, the first outgoing RF signal, and the second outgoing RF signal through a common port.

Description

BACKGROUNDField of the Invention[0001]The present disclosure generally relates to a multiport waveguide device. In particular, the present disclosure relates to a multiport waveguide device having multiple receiving ports and / or multiple transmitting ports for the simultaneous reception and / or transmission of radio frequency (“RF”) signals.Background Information[0002]Various waveguide devices are capable of receiving or transmitting RF signals. Conventional waveguide devices can be a hollow conductive metal pipe used to carry high frequency radio waves, particularly microwaves. The geometry of a waveguide reflects its function; in addition to more common types that channel the wave in one dimension, there are two-dimensional slab waveguides which confine waves to two dimensions.SUMMARY[0003]It has been determined that existing conventional assemblies are costly and not suited for mass production. Existing assemblies also typically require electromechanical switching between multiple...

AI Technical Summary

Benefits of technology

The present patent describes a multiport waveguide device that allows for the simultaneous reception and transmission of multiple RF signals. The device uses an orthogonal mode transducer to integrate two polarization signals for the same antenna. Using a 90 degree waveguide twist, the device achieves high yield split manufacturing to ensure consistent RF performance after assembly. The device's compact design and inexpensive construction make it ideal for wide band radio design with low insertion loss. The multiport waveguide device provides a simple and cost-effective solution for RF signal integration.

Problems solved by technology

It has been determined that existing conventional assemblies are costly and not suited for mass production.

Existing assemblies are also typically large and bulky, experience waveguide insertion losses, and / or do not allow a single circuit board to be used for all of the receiving and transmitting ports.
