60 GHz Omni-directional segmented loop antenna

The design, simulation and fabrication of a planar fragmented loop antenna with capacitive loads at 60 GHz frequency band is reported in this paper. The loop antenna has a nearly omni-directional radiation pattern required for many IEEE 802.11ad applications, a simulated bandwidth of 6 GHz, and a realized gain of 2 dBi. The measured input matching bandwidth without deembedding the connector effect is nearly 2 GHz. The HPBW in azimuth plane is 360°.
