EXTERNAL LTE MULTI-FREQUENCY BAND ANTENNA

摘要

An antenna is provided. The antenna includes a substrate having a first end and a second end opposite to the first end, wherein a direction from the first end to the second end is an extending direction of the antenna; a radiating portion; a feed-in conductor; and a ground portion electrically connected to the radiating portion, coupled to the feed-in conductor, disposed on the substrate from the first end along the extending direction, and including a main ground conductor; and a high frequency band bandwidth adjusting conductor extended from the main ground conductor along the extending direction.

1. An antenna, comprising:
a substrate including a first surface and a second surface opposite to the first surface; a ground portion disposed on the first surface, and including a main ground conductor and a high frequency band bandwidth adjusting conductor extended from the main ground conductor, wherein the main ground conductor has a grounding terminal; a J-shaped radiating portion disposed on the first surface, and including:
a first grounding conductor having a first length and a first width, and extended from the grounding terminal;a second grounding conductor having a second length and extended from the first grounding conductor along a first direction, wherein a first angle is formed between the first grounding conductor and the second grounding conductor; anda radiating conductor having a third length and a second width, and extended from the second grounding conductor along a second direction, wherein a second angle is formed between the second grounding conductor and the radiating conductor; and an L-shaped feed-in conductor disposed on the second surface, wherein: a capacitive coupling is formed between the L-shaped feed-in conductor and the J-shaped radiating portion; the first length is larger than the third length; the third length is larger than the second length; and the second width is larger than the second length.
