The design of an antenna feed system that includes amplification of the signal is presented. The feed includes power division (in this initial example a 1 to 2 division is shown) and the amplification section. The design is made in the groove gap waveguide technology in the X band and can be easily scaled to millimeter frequency bands. Besides the manufacturing advantages of groove gap waveguide when...
A contactless, in-line, wideband and low-loss micro strip to GrooveGap waveguide transition operating at X-band is presented. The principle of operation is based on transforming EM fields from the SIW to the RidgeGap waveguide mode via near field electromagnetic coupling. This is advantageous, since the proposed solution avoids the use of metal contact between the SIW and one of the waveguide parts...
An optimized self-diplexed slot antenna is presented. The antenna is designed using the novel low loss inverted microstrip gap waveguide technology, formed between two parallel metal plates without the requirement of electrical contact between these plates. A texture of screws is used to provide the needed AMC condition in order to make the manufacturing low cost. The diplexer layout has been optimized...
Low cost low-loss self-diplexed slot antenna is described. The antenna is built using a novel microstrip waveguide technology, formed between two parallel metal plates without the requirements of electrical contact between these plates. The diplexer is realized by using a texture of screws as Artificial Magnetic Conductor (AMC) and two parallel coupled lines passband filters (BPFs), and the radiating...
