ANTENNA DEVICE AND COMMUNICATION DEVICE - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240243488 titled 'ANTENNA DEVICE AND COMMUNICATION DEVICE

The patent application describes an array antenna housed in a housing with multiple antenna elements facing an inside surface and arranged in a first direction. A waveguide is connected to the antenna elements and extends towards the inside surface of the housing, with one end facing the housing and the other end facing the antenna array. The length of the waveguide on the housing side is greater than the length on the antenna side, providing improved antenna gain without increasing the size of the antenna module.

Questions about Array Antenna with Waveguide: 1. How does the waveguide contribute to improving antenna gain? The waveguide helps to focus and direct the electromagnetic waves emitted by the antenna elements, resulting in enhanced gain. 2. What are the potential drawbacks of using a waveguide in an array antenna system? While waveguides can improve antenna performance, they may add complexity to the system and require precise engineering for optimal results.

Original Abstract Submitted

an array accommodated in a housing includes multiple antenna elements. the antenna elements face an inside surface of the housing and are arrayed in a first direction at least one-dimensionally. a waveguide is coupled to the antenna elements of the array antenna and extends from the array antenna toward the inside surface of the housing. the waveguide has a housing-side end face facing the inside surface of the housing and an antenna-side end face facing the array antenna. a length from one end to an opposite end of the housing-side end face in the first direction is greater than a length from one end to an opposite end of the antenna-side end face in the first direction. an antenna device that can improve antenna gain without increasing the size of the antenna module is provided.
