Double Bi-quadantenna for WiGig applications

Wireless Gigabit (WiGig) presents advantages against IEEE 802.11ac´s WiFi in 2.4 and 5 GHz such as faster data rates, intermittent connection, and power efficient transmissions in 60GHz band. However, WiGig antennas have a common disadvantage which is complexity with their designs that provides lesser availability of WiGig connection. The study aims to develop an improved gain and beamwidth with less complexity in the antenna design and components. A double bi-quad antenna design with reflector base for WiGig was presented in this study. The proposed antenna was known for its quick design, simple components, and performance. It consists of four square loops (quads) of the same size as a radiating element and a metallic plate or grid as reflector. This antenna simulation was conducted from 57 GHz to 64 GHz and showed a peak gain of 12.9dBi in the vertical plane and good directivity with 90°beamwidth. In the 60 GHz band, radiation efficiency was 100% while the maximum radiation efficiency was 104.3% at 64 GHz.
