A radio frequency circuit structure for transmitting radio signals includes a lower guide portion having a plurality of photocurable layers deposited on a substrate and an upper guide portion interfacing with the lower guide portion to define a guiding geometry. The upper guide portion may also include a plurality of photocurable layers deposited on a second substrate. A method for fabricating the radio frequency circuit structure includes depositing the plurality of photocurable layers on the substrate. A portion of each photocurable layer of the plurality of photocurable layers is exposed to ultraviolet light to form a latent image. The plurality of photocurable layers is developed to remove the portions not exposed to ultraviolet light to form a guide portion. The guide portion may be metalized and closed to form a guiding geometry. A lower guide portion may be closed by an upper guide portion formed in substantially the same manner as the lower guide portion.
