Abstract

A low-profile antenna having four directional beam patterns using loop elements has been proposed. The proposed antenna is vertically polarized and has four directional beams for sensor nodes. The thickness of the antenna is only 3.2 mm (0.11 effective wavelength) resulting in a low-profile structure. Simulated and measured average gain of 8.0 dBi and 5.6 dBi are obtained, respectively.
