WIDE BANDWIDTH ANTENNA
First Claim
Patent Images
1. A wide bandwidth antenna, which is connected to at least one signal line for transmitting and receiving wireless signals, comprising:
- at least a substrate made of a dielectric material;
at least a signal input terminal provided on said substrate for the establishment of electrical connection with said signal line for signal input and output; and
at least an antenna module, disposed on said substrate, comprises a plurality of antenna elements with spiral geometric patterns, wherein said geometric pattern of the first said antenna element is formed by an electrically conductive spiral trace winds from the starting point at the outside of said geometric pattern toward inside, and then winds back again from inside toward outside, andcontinuing from an end point of said geometric pattern of said first antenna element, the electrically conductive spiral trace of the second said antenna element winds from the outside of the geometric pattern toward inside, and then winds back from inside toward outside to form a second antenna element, continuing these procedures until the needed number of said antenna elements is established, andsaid starting point of the spiral geometric pattern of said first antenna element is connected to said signal input terminal.

Abstract
A wide bandwidth antenna, wherein, at least an antenna module is provided on a substrate, said antenna module includes a plurality of antenna elements having spiral geometric patterns, that are connected one by one in series. Each antenna element is formed by an electrically conductive trace winding from outside said spiral geometric pattern to inside, then it winds back from inside to outside. A first antenna element in the antenna module is connected to a signal input terminal, and that is connected electrically to a signal transmission line.
