QVE ultra-wideband feedWorking frequency band: 37.5-86GHzWorking bandwidth: ＞48.5GHzGain: ≥20.3dBi (Q band)≥21.5dBi (V band)≥18.8dBi (E band)Key product breakthroughsThe existing application has a dual-band broadband feed in the QV band, with two ports of left-handed and right-handed circular polarization, and each port has an operating frequency of 37.5~42.5GHz and 46.5~51.5GHz. Compared with the QV band broadband high-performance feed, the operating frequency of each port of the QVE feed is extended to four working frequency bands of 37.5~42.5GHz, 46.5~51.5GHz, 71~76GHz, and 81~86GHz. Each port has left-handed and right-handed circular polarization in 4 frequency bands. This ultra-wideband high-performance dual-polarization feed works in the three bands of Q, V, and E at the same time. There is no relevant literature at home and abroad, showing a very high technical level.
