Method for tuning an electrically small antenna
A method of tuning an electrically small antenna comprising a radiating element and a support structure comprises applying a force to the support structure to change a shape or a dimension of the radiating element to increase or decrease a frequency at which the electrically small antenna resonates.
1. A method of tuning an electrically small antenna comprising a radiating element and a support structure supporting the radiating element, the method comprising:
applying a first force in a first direction to the support structure in a first area; and applying a second force in a second direction opposite to the first direction to the support structure in a second area spaced apart along a vertical axis from the first area, the combination of the first force and the second force to apply a torsion to the support structure that changes a shape or a dimension of the radiating element to increase or decrease a frequency at which the electrically small antenna resonates.
2. The method of claim 1 , wherein the electrically small antenna is a hemispherical helical monopole antenna.
3. A method of tuning an electrically small antenna comprising a radiating element having a single segment and a support structure supporting the radiating element and having a hemispherical shape, the method comprising:
positioning the electrically small antenna on an object such that a lower portion of the support structure is rigidly attached to the object; and
applying a torsional force to the support structure in a direction that changes a shape or a dimension of the radiating element to increase or decrease a frequency at which the electrically small antenna resonates.
4. The method of claim 3 , wherein the electrically small antenna is a hemispherical helical monopole antenna.
