Abstract

This work presents a 64-GHz substrate integrated waveguide (SIW) cavity-backed antenna, whose bandwidth is extended through the complementary multiple annular slots on the front and back sides of the SIW cavity, respectively. A perturbed TE210 mode with two broadside radiation patterns in opposite directions can be observed under the double-sided slots. A Rogers RO4003C substrate is used to manufacture this antenna through a printed circuit board process. With the -10- dB S11 criteria, the measured impedance bandwidth is 3.2 GHz. The measured realized gains at 64 GHz in the two broadside directions are 6.4 dBi and 3.4 dBi, respectively. Furthermore, an over-the-air experiment with a QPSK modulation signal was conducted to validate the double-sided radiation.
