Abstract :
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 slot is placed in the smooth top plate. The diplexer layout has been optimized in order to ensure compactness. The diplexer shows excellent performance in terms of high isolation and low insertion loss.
