dc.description.abstractIn this paper, two compact planar substrate integrated waveguide (SIW) cavity-backed antennas are proposed for wireless local area network (WLAN) at 5.5GHz and wireless body area network (WBAN) at 5.8GHz. The miniaturization is achieved with the concept of quarter-modetopology, and the size of the cavity is reduced up to one-fourth of the circular SIW cavity. A L-shaped slot is etched on the top plane for miniaturization, and antenna-1 is realized which resonates at 5.5GHz. A metal strip has been added in the middle section of the slot, and antenna-2 is realized, which resonates at 5.8GHz. Both proposed antennas are tested in free space, while the performance of antenna-2 is investigated for on-body condition. In free space, the measured impedance bandwidths of the antenna are 160 MHz and 210MHz at 5.5 GHz and 5.8GHz, respectively. The radiation efficiency of the antenna is 89.4% in free space and 57% on phantom at 5.8GHz. Both measured and simulated results are observed, and they are in a good agreement.
