Non-Foster Active Impedance Circuit for Electrically Small Antennas |
| 摘要 |
An antenna comprising: a driven element; an input feed coupled to the driven element wherein the input feed is configured to be connected to a receiver; a non-Foster circuit having a negative impedance, wherein the non-Foster circuit is configured to actively load the antenna at a location on the antenna other than at the input feed; and wherein the antenna may be contained within an imaginary sphere having a radius a, and wherein the product ka is less than 0.5, where k is a wave number. |

1. An antenna comprising:
a driven element; an input feed coupled to the driven element wherein the input feed is configured to be connected to a receiver; a non-Foster circuit having a negative impedance, wherein the non-Foster circuit is configured to actively load the antenna at a location on the antenna other than at the input feed; and wherein the antenna may be contained within an imaginary sphere having a radius a, and wherein the product ka is less than 0.5, where k is a wave number. |
