Abstract
Official abstract text for this publication.
A system for generating microwave energy includes a microwave generator that generates first and second microwave signals, a transmission line and a dual antenna microwave device. The transmission line transmits the first and second microwave signals to the microwave device. The microwave device includes a first antenna proximal a second antenna and a dual-sided choke positioned therebetween. The first antenna receives the first microwave signal from the transmission line between a first conductor and a second conductor and the second antenna receives the second microwave signal between the second conductor and a third conductor. The dual-sided choke includes a first and a second antenna choke circuit. The first antenna choke circuit limits the propagation of electromagnetic fields generated by the first antenna toward the second antenna and the second antenna choke circuit limits the propagation of electromagnetic fields generated by the second antenna toward the first antenna.
