Introduction,and eyes of the whole communication system, which is the interface between the system and the external media. All systems based on radio wave communication are inseparable from the antenna, and for these communication systems, the selection and design of the antenna will directly affect the performance of the whole system.作者: 豎琴 時(shí)間: 2025-3-22 02:07 作者: 畸形 時(shí)間: 2025-3-22 08:33 作者: Arteriography 時(shí)間: 2025-3-22 11:27 作者: 有惡臭 時(shí)間: 2025-3-22 15:16 作者: Barrister 時(shí)間: 2025-3-22 20:16 作者: enlist 時(shí)間: 2025-3-22 21:29 作者: Bridle 時(shí)間: 2025-3-23 02:32
