AGC has filed a patent for an antenna design that includes two conductor plates, with one plate placed inside the other at a distance. The first conductor plate has a U-shaped portion with a front portion and two side portions, while the second conductor plate also has a U-shaped portion with a front portion and two side portions. The front portions of both plates are opposed to each other, and the first front portion has a slot dividing it into two surface portions, each with a feeding point.

The patent filed is for a u-shaped antenna with feeding points
A recently filed patent (Publication Number: US20230318192A1) describes an antenna design with specific features and configurations. The antenna consists of a first conductor plate and a second conductor plate, with the second plate positioned within the first plate at a distance. The first conductor plate includes a U-shaped portion, while the second conductor plate also has a U-shaped portion. The front portions of both plates are opposed to each other, with the first front portion having a slot that divides it into two surface portions. The first surface portion has a first feeding point, and the second surface portion has a second feeding point.
The antenna further includes side portions between the front and side surfaces, with each side having at least one line segment. The slot extends in a direction intersecting both sides and is substantially orthogonal to them. The front portions of both conductor plates extend in a direction substantially orthogonal to their respective side portions. The second front portion is parallel to the first front portion and extends in a direction substantially orthogonal to the third and fourth side portions of the second conductor plate.
The first and second side surfaces are substantially parallel to the third and fourth side surfaces, respectively. The size of the second conductor plate (L2) is at least 0.75 times and at most 1.5 times as long as the size of the first conductor plate (L1). The second conductor plate also has a portion protruding from the first conductor plate in a side view.
The feeding points of the antenna are located in the vicinity of the slot's central portion. The front portion of the first conductor plate is rectangular, while the slot is oblong. The first surface portion has a size (W1), and the second surface portion has a size (W2), with W2 being at least 0.1 times and at most 10 times as long as W1.
The distances between the first and third side portions and between the second and fourth side portions are denoted as d1 and d2, respectively. At least one of d1 or d2 is at least 0.05 times and at most 0.5 times the effective wavelength (?g) of the radio wave transmitted and received by the antenna. The distance between the first and second front portions (d3) is larger than 0 and at most 0.3 times ?g.
The antenna may also include a feeding line and a planar waveguide, both electrically connected to the first and second feeding points. The second conductor plate may have a parasitic conductor.
Overall, this patent describes a specific antenna design with various features and configurations that aim to enhance its performance in transmitting and receiving radio waves.
