Broadband Waveguide Feed for Parabolic Reflectors حسب P. Bhushan Mital

"…This paper describes the design and development of an ridged horn to match the waveguide impedance to freespace impedance so that the horn could be used as a feed for an offset-fed parabolic reflector over a wide band of frequencies, i.e., C and X bands (4.2 to 10.2 GHZ). …"

Broadband Multilayered Array Antenna with EBG Reflector حسب P. Chen, X. D. Yang, C. Y. Chen, Z. H. Ma

"…A broadband stacked slot coupling microstrip antenna array with EBG structure reflector is proposed. Test results indicate that the proposed reflector structure can effectively improve the directivity pattern of stacked antenna and aperture coupled antenna, promote the front-to-back ratio, and reduce the thickness of the antenna. …"
