An Omnidirectional Cylindrical DRA with A Cone Ground for WLAN Applications
To meet the omnidirectional and high gain require- ments of wireless local area networks (WLAN) communication systems,a centrally probe-fed cylindrical dielectric resonator antenna (DRA) with a cone ground is proposed.Generally,most of the DRA is set on a metallic ground plane with a suitable size.However,the maximum radiation direction may deviate from the intended horizontal direction and the gain is often reduced badly,when the ground plane enlarges to a certain size in many applications.To solve this problem,a metallic ground in cone shape is introduced.Then a cylindrical DRA with the cone ground is designed.The simulated results show that the return loss is less than -10dB from 2.31GHz t0 2.71GHz,which has a complete coverage of WLAN band and is wider than the cylindrical DRA with normal ground plane.And the maximum radiation direction is almost in horizontal direction with only 50 upward-bending.Moreover,the gain in the horizontal direction is not only reduced,but also 0.8dBi higher than the conventional cylindrical DRA.
