Abstract
A heater for a radio frequency (RF) antenna and method for using the same are disclosed. In one embodiment, an antenna comprises a physical antenna aperture having an array of RF antenna elements; and a plurality of heating elements, each heating element being between pairs of RF elements of the array of RF elements.

An antenna comprising:
- a physical antenna aperture having an array of radio frequency (RF) antenna elements formed with first and second substrates and a liquid crystal (LC) layer between the first and second substrates, the first substrate being an iris substrate;
- and
- a plurality of heating elements between the first and second substrates and interleaved between RF antenna elements in the array to heat the LC layer, each heating element integrated with iris elements as part of the iris layer on the iris substrate and contained within an area between a distinct pair of adjacently located RF elements in the array of RF elements.
