PROJECT TITLE :
Ridged Horn Antenna With Adjustable Metallic Grid Sidewalls and Cross-Shaped Back Cavity
This letter proposes a new ridged horn antenna with adjustable metallic grid sidewalls and a cross-formed back cavity. An improved style of the coaxial-line-to-ridged-waveguide transition is introduced to improve the pattern behavior and come back-loss performance of the horn antenna across the complete frequency band. The measurement results prove that there are not any distortions at higher frequencies. The frequency range of this horn antenna is 0.8-20 GHz, and this design exhibits improved performance in terms of gain, VSWR, and radiation pattern.
