If you want to summon your own guardian angel for your protection from all kind of evils then use chief verses of Holy Quran - The Ayaut-ul-Kursi.
When you go to bed, recite Ayat-ul- Kursi (2:255) for there will be a guardian appointed over you from Allah, and Satan will not be able to approach you till morning.
Hadith narrated by Abu Huraira, in which Prophet Muhammad (peace be upon him) said: "Whoever recites Ayatul Kursi after every prayer, there will be a guard from Allah who will protect him from all kinds of evil." (Sahih Muslim, Book 4, Hadith 845).
