Abstract

The present invention relates to a new on-body dual antiphase antenna design and a plurality of its modifications to better transmit a radio frequency signal into human or animal body, or receive a radio frequency signal from human or animal body. The antiphase transmission and/or reception is achieved by connecting each individual patch antenna to a 180 degrees microwave power splitter or to a 180 degrees microwave power combiner.

Claims

1. A dual antiphase antenna transmitting into a mammal body and comprising:

a top and a bottom,

at least two individual patch antennas, wherein the at least two individual patch antennas are spaced closely to each other and wherein each antenna further comprises;

a dielectric substrate comprising a first side and a second side;

a metal radiating patch in close contact with the mammal body;

wherein the metal radiating patch is on the first side of the dielectric substrate;

a metal ground plane located on the second side of the substrate;

wherein the first antenna and the second antenna are driven with the phase difference of 180°

.

3. The dual antiphase antenna of claim 1 further comprising coaxial probe feeds for each of the at least two individual patch antennas.

4. The dual antiphase antenna of claim 1 further comprising microstrip feeds for each of the at least two individual patch antennas.

5. The dual antiphase antenna of claim 1 further comprising two separate antenna matching networks.

6. The dual antiphase antenna of claim 1 further comprising a 180°

power splitter.

7. The dual antiphase antenna of claim 1 further comprising a 180°

power splitter connected to a transmitter.

8. The dual antiphase antenna of claim 1 wherein the at least two individual two patch antennas are replaced by at least two planar inverted F antennas.

9. The dual antiphase antenna of claim 1 wherein the at least two individual patch antennas are replaced by at least two printed loop antennas.

10. The dual antiphase antenna of claim 1 wherein the at least two individual patch antennas are replaced by at least two printed dipole antennas.

11. The dual antiphase antenna of claim 1 wherein the at least two individual two patch antennas are replaced by at least two printed monopole antennas.

2. A dual antiphase antenna receiving from a mammal body and comprising:

a top and a bottom,

at least two individual patch antennas, wherein the at least two individual patch antennas are spaced closely to each other and wherein each antenna further comprises;

a dielectric substrate comprising a first side and a second side;

a metal radiating patch in close contact with the mammal body;

wherein the metal radiating patch is on the first side of the dielectric substrate;

a metal ground plane located on the second side of the substrate;

wherein the signals from the first antenna and the second antenna are combined with the phase difference of 180°

.
