Abstract
An RF choke for an oven having a door movable between an open position and a closed position to interface with an opening defined in a cooking chamber of the oven includes a base portion and a plurality of resonant elements formed in rows. The cooking chamber is defined at least in part by a top wall, a bottom wall, a first sidewall and a second sidewall. The RF choke is disposed at a portion of the door facing the cooking chamber when the door is in the closed position. The base portion is a metallic sheet and is disposed in a first plane substantially parallel to a second plane in which the door lies. The resonant elements are folded out of the first plane toward the door to define a top row of resonant elements, a bottom row of resonant elements, a first side row of resonant elements and a second side row of resonant elements, which are proximate to respective ones of the top wall, the bottom wall, the first sidewall and the second sidewall of the cooking chamber when the door is in the closed position. At least one of the rows is folded out of the first plane at a different angle relative to the first plane than other ones of the rows.
