Broadband monopole antenna with dual radiating structures
First Claim
1. An antenna, comprising:
- a ground plane;
a first radiating structure having a symmetric configuration along a central axis,a first feed point electrically connected to a base of said first radiating structure along said central axis; and
a single first slot physically partitioning the first radiating structure into a first subset of radiating members;
a first reactive loading element formed in central location of said first radiating structure to modify the operating frequency bandwidth, input impedance, resonant frequency, polarization characteristics, or any combination thereof of the antenna wherein the first reactive loading element is comprised of a first open-ended strip along said central axis, sides of said first open ended strip being defined by said first slot.

Abstract
A broadband monopole antenna with dual-radiating elements is provided. In one embodiment, an antenna comprises a ground plane; a first radiating structure having a symmetric configuration along a central axis, comprising a first feed point electrically connected to the base of said first radiating structure along said central axis and a first slot with a corresponding first open-ended strip along said central axis; and a second radiating structure conjoined with said first radiating structure having a symmetric configuration along said central axis, comprising a second feed point electrically connected to the base of said second radiating structure along said central axis and a second slot with a corresponding second open-ended strip along said central axis; and wherein the antenna resonates and operates at a plurality of resonant frequencies.

17. A device in a wireless communication system, comprising:
-
a transmitter for transmitting information over a frequency band; a receiver for receiving information over a frequency band; and an antenna electrically connected to said transmitter and said receiver, comprising; a ground plane; a first radiating structure, comprising; a first feed point electrically connected to a base of said first radiating structure along a central axis; and a single first slot physically partitioning the first radiating structure into a first subset of radiating members; and a first reactive loading element formed in central location of said first radiating structure; a second radiating structure conjoined with said first radiating structure, comprising; a second feed point electrically connected to the base of said second radiating structure along a central axis, wherein said first and second feed points are configured to electrically connect said antenna to said transmitter, said receiver, or both; and a single second slot physically partitioning the second radiating structure into a second subset of radiating members; and a second reactive loading element formed in a central location of said second radiating structure, the first reactive loading element and the second reactive loading element to modify the operating frequency bandwidth, input impedance, resonant frequency, polarization characteristics, or any combination thereof of the antenna, wherein the first reactive loading element is comprised of a first open-ended strip along said central axis, sides of said first open ended strip being defined by said first slot. - View Dependent Claims (18)
