Integrated waveguide slot antenna for V-band based on LTCC technology

A design of LTCC multi-layer slot antenna is introduced, which is based on classical design theory of slot antenna and LTCC technology. According to full-wave electromagnetic(EM) simulation, the antenna, intended for use in high integrated 60 GHz radios, has achieved an acceptable impedance bandwidth from 53 GHz to 70 GHz and a peak gain of 5.2 dB at 68.5 GHz.
