Document Type and Number:
WIPO Patent Application WO/2023/010953
Kind Code:
A1
Abstract:
A multi-frequency multi-beam lens antenna, comprising a Luneburg lens, two low-frequency oscillators and four high-frequency oscillators. The operating frequency of an individual low-frequency oscillator is within the range of 694-960 MHz, and two channels at ±45° polarization can be realized; and for each polarization, an independent frequency band of 703-798 MHz (700 M) and an independent frequency band of 885-960 MHz (900 M) are separated out by means of a combiner, and the two low-frequency oscillators obtain four respective channels in the frequency band of 700 M and the frequency band of 900 M. The operating frequency of an individual high-frequency oscillator is within the range of 1710-2690 MHz, and two channels at ±45° polarization can be realized; and for each polarization, an independent frequency band of 1710-1830 MHz (1800 M) and an independent frequency band of 1885-2025 MHz (FA) are separated out by means of a combiner. In addition, channels in the frequency band of 1800 M are connected in parallel in pairs by means of a splitter, such that the total number of channels in the frequency band of 1800 M is halved. In this way, the four high-frequency oscillators obtain two respective channels in the frequency band of 1800 M at ±45° polarization, and four respective channels in the frequency band of FA at ±45° polarization. The antenna has the characteristics of a simple structure, a scientific design, a small windward area, a light weight, a simple feed network, low loss, high efficiency, etc.
