Abstract

For the first time, an extended hemispherical integrated lens antenna on a low-cost substrate, FR408HR, is presented. The antenna is designed for industrial and automotive radar sensor applications operating in the 24 GHz ISM band. The proposed antenna has a gain of 15.2 dBi, low sidelobes, and half-power beamwidth of 16 degrees. To reduce the cost, we used low loss materials; Teflon for the lens and low-cost FR408HR as a patch antenna substrate. The size of the reported 24 GHz antenna is small. The diameter of the base of the lens is 38 mm (3 times of free space wavelength), and its height is 43.5 mm (with an extended height of 24.5 mm). Simulated results match well with measurements.
