Abstract
According to the two-dimensional aperture principle, directivity and gain are expected to be proportional to the aperture area of an antenna or antenna array. Our simulations and measurements of an end-fire radiation antenna array overturn this conventional wisdom. The gain of an end-fire antenna array is found to be much higher than that calculated by the two-dimensional aperture principle. We introduce a length component into the two-dimensional aperture principle and propose a three-dimensional aperture principle. A four-element end-fire antenna array is designed and measured to verify the correctness of this new principle. The three-dimensional aperture principle opens a pathway to novel types of aperture utilization.
Highlights
According to various track deployment and performance indicators, the antenna aperture can reach tens to hundreds of square meters.[11–13]. Reflector antennas are another approach whereby high gain can be achieved by increasing the antenna aperture area
The reflectarray antenna, which combines the advantages of reflector antennas and array antennas, has the characteristics of high gain, high efficiency, and flexible beam control.[22–29]
We report a threedimensional aperture principle as follows: GV
Summary
Reflector antennas are another approach whereby high gain can be achieved by increasing the antenna aperture area. The high-gain requirement of an antenna is usually achieved by increasing the aperture area. According to our new three-dimensional aperture principle, the gain of the antenna can be increased through the three-dimensional scale of the antenna volume.
