ABSTRACT:
A helical antenna, which is matched to the desired microwave frequency of 915 MHz, comprises a helix having a linear length which is in the range of 74 to 112 mm or a non-zero integer multiple thereof, and which delivers microwave energy in an optimal heating pattern with little reflected power.
