A compact cavity-backed Fresnel zone plate (FZP) lens antenna, integrated in low-temperature co-fired ceramic (LTCC) is proposed to achieve high gain at 270 GHz band. The gain is enhanced by using the ...

A broadband substrate integrated waveguide (SIW) cavity-backed slot antenna for endfire applications is presented in the letter. The antenna employs a semiclosed SIW cavity with one sidewall removed ...
