spe - 14 - 8 - 039 / a/wy page 2 of 13 1. introduction this unique patent pending high gain , high efficiency embedded ceramic patch antenna is designed for professional wi - fi du al - band ieee 802.11 applications . it is mounted via pin and double - sided adhesive. the passive patch offers stable high gain response from 4 dbi to 6dbi on the 2.4ghz band and from 5dbi to 8dbi on the 5 ~6 ghz band. efficiency values are impressive also ac ross the bands with on average 60%+. the w d p.25s high gain , high efficiency performance is the perfect solution for directional dual - band wifi application which need long range but which want to use small c ompact embedded antenna s . the much higher gain a nd efficiency of the wdp.25 over smaller less efficient more omni - directional chip antennas (these typically have no more than 2dbi gain, 30% efficiencies) means it can deliver much longer range over a wide sector. typical applications are access points tablets high definition high throughput video streaming routers high data mimo bandwidth routers automotive home and industrial in - wall wifi automation d rones /quad - copters uav long range wifi remote control applications the wdp patch antenna has two di stinct linear polarizations, on the 2.4 and 5ghz bands, increasing isolation between bands . custom tuned versions for different ground - planes and housing environments can be made subject to a minimum order quantity. contact your regional taoglas office for support to integrate and test this antenna performance in your device.
