1. Iwọn igbohunsafẹfẹ igbohunsafẹfẹ ati awọn abuda ti ara
eriali RF:
Iwọn igbohunsafẹfẹ iṣẹ jẹ 300 kHz - 300 GHz, ti o bo igbesafefe igbi alabọde (535-1605 kHz) si igbi millimeter (30-300 GHz), ṣugbọn awọn ohun elo mojuto ni ogidi ni <6 GHz (bii 4G LTE, WiFi 6). Gigun gigun naa gun (iwọn centimita si ipele mita), eto naa jẹ dipole ati eriali okùn, ati ifamọ si ifarada jẹ kekere (± 1% gigun jẹ itẹwọgba).

Eriali makirowefu:
Ni pato 1 GHz - 300 GHz (microwave si millimeter), awọn ẹgbẹ igbohunsafẹfẹ ohun elo aṣoju gẹgẹbi X-band (8-12 GHz) ati Ka-band (26.5-40 GHz). Awọn ibeere gigun gigun kukuru (ipele milimita):
