Abstract
A loop antenna with a parasitic element inside is described. In an embodiment, the loop antenna comprises a loop element that has a feed contact and a ground contact. The loop antenna further comprises a first parasitic element that is arranged inside the loop element and that acts as a first slot radiator. A first end of the first parasitic element is physically connected to the loop element thereby forming a closed end of the first slot radiator. The first slot radiator further has an open end that is closer to the feed contact and the ground contact than its closed end.

A loop antenna, comprising:
- a loop element having a feed contact and a ground contact;
- and
- a first parasitic element arranged inside the loop element and acting as a first slot radiator, wherein a first end of the first parasitic element is physically connected to the loop element thereby forming a closed end of the first slot radiator, and wherein the first slot radiator further has an open end that is closer to the feed contact and the ground contact than its closed end.
A loop antenna, comprising:
- a loop element having a feed contact and a ground contact;
- and
- a first parasitic element arranged inside the loop element and acting as a first slot radiator, wherein a first end of the first parasitic element is physically connected to the loop element thereby forming a closed end of the first slot radiator, and wherein the first slot radiator further has an open end that is closer to the feed contact and the ground contact than its closed end,
- wherein the first parasitic element first extends substantially linearly from the closed end of the first slot radiator towards the open end of the first slot radiator and then bends along one of the feed contact and the ground contact at the open end of the first slot radiator.
A mobile apparatus, comprising:
- at least one processor;
- at least one memory storing program instructions;
- and
- a loop antenna comprising:
- a loop element having a feed contact and a ground contact;
- and
- a first parasitic element arranged inside the loop element and acting as a first slot radiator, wherein a first end of the first parasitic element is physically connected to the loop element thereby forming a closed end of the first slot radiator, and wherein the first slot radiator further has an open end that is closer to the feed contact and the ground contact than its closed end.
