Abstract
An antenna for broadband multiplexing is disclosed. The antenna includes a first set of curved dipole members and a second set of curved dipole members arranged in a helical shape. One set of the dipole members is set with approximately 36° between each dipole member in the set. The other set of dipole members is set with approximately 27.5° between each dipole member in the set. The setting of the dipole members at the designated angles increases the bandwidth that the antenna can accommodate.
Claims22
An antenna system, comprising:
- a first curved dipole member;
- a first connecting member, wherein said first curved dipole is affixed to one end of the first connecting member wherein said first dipole members forms a straight line between its terminal ends when viewed along the axis of the first connecting member;
- a second curved dipole member;
- a second connecting dipole member, wherein said second curved dipole member is affixed to one end of said second connecting member, and wherein said second dipole member forms a straight line between its terminal ends when viewed along the axis of the second connecting member,
- wherein said second connecting member intersects said first connecting member, and wherein a first angle between said straight line formed by said first curved dipole member and said second connecting member different from a second angle between said straight line formed by said second curved dipole member and said axis of said first connecting member.
An antenna comprising:
- a first curved dipole means;
- a first connecting means, wherein said first curved dipole means is affixed to one end of the first connecting means wherein said first curved dipole means forms a straight line between its terminal ends when viewed along the axis of the first connecting means;
- a second curved dipole means;
- a second connecting dipole means, wherein said second curved dipole means is affixed to one end of said second connecting means, and wherein said second curved dipole means forms a straight line between its terminal ends when viewed along the axis of the second connecting means,
- wherein said second connecting means intersects said first connecting means, and wherein a first angle between said straight line formed by said first curved dipole means and said second connecting means is different from a second angle between said straight line formed by said second curved dipole means and said axis of said first connecting means.
A method of transmitting radio frequency signals, comprising the steps of:
- transmitting a radio frequency signal to a quadrapole ring antenna;
- and
- radiating said radio frequency signal from said antenna;
- wherein said quadrapole ring antenna has a first and second dipole member affixed at opposite ends of a first connecting member and wherein said first and second dipole members form straight lines between their terminal ends when viewed along the axis of the first connecting member and wherein said quadrapole ring antenna has a third and a fourth dipole member affixed at opposite ends of a second connecting member and wherein said third and fourth dipole members form straight lines between their terminal ends when viewed along the axis of the second connecting member and wherein said second connecting member intersects said first connecting member, and wherein a first angle between said straight line formed by said first dipole member and said second connecting member is different from a second angle between said straight line formed by said third dipole member and said axis of said first connecting member.
