摘要： This application discloses a transformative apparatus, an arrayed transformative apparatus, and a communication device. The transformative apparatus provided in this application includes a transmission member, a converter antenna, a first waveguide, and a first guiding member. The transmission member is configured to receive and transmit an electrical signal having a first mode. The converter antenna is configured to: receive the electrical signal from the transmission member, form local radiation, and excite an electrical signal having a second mode in the first waveguide. The first waveguide is configured to receive and transmit the electrical signal having the second mode. The first guiding member is configured to guide an electrical signal output from the converter antenna into the first waveguide. The transformative apparatus provided in this application changes a mode of an electrical signal on the transmission member by using the converter antenna, and guides the electrical signal to the first waveguide by using the first guiding member. This reduces a leakage of the electrical signal in a transfer process from the transmission member to the first waveguide, and improves transfer efficiency of the electrical signal between different types of transmission lines, so that the electrical signal can be stably and efficiently transmitted.

摘要： This document describes apparatuses, methods, and systems for a hybrid horn waveguide antenna. The hybrid horn waveguide antenna includes a waveguide, described in two sections, and an antenna section having both flaring features and step features. The first waveguide section is electrically coupled to a transmitter/receiver (e.g., transceiver) and defines an energy path along an x-axis. The second waveguide section transitions the energy path to travel along a z-axis. The antenna section has a first aperture that is coupled to the second waveguide section and includes flaring wall features in one plane (e.g., the E-plane) and step features in a second plane (e.g., the H-plane). The waveguide may further include an iris between the first waveguide section and the second waveguide section. Further, the hybrid horn waveguide antenna section may be formed from an upper structure and a lower structure manufactured via injection molding and then mated.
