Abstract

This article presents a compact microstrip meander-line antenna for sensor network applications in the 290 MHz band. The antenna is fed by coplanar waveguide and its dimension is 15 mm × 15 mm × 2 mm. Because of the use of a very high relative permittivity substrate (εr = 90) and meander-line structure simultaneously, the side length of the designed antenna is about λg/12 (λg is the guided wavelength) so that the circuit size is reduced greatly. Measurements verify that the proposed antenna has bandwidth of 12% at the resonant frequency of 293 MHz. Also, the radiation patterns measured at resonance frequencies are very close to omnidirectional in the E-plane.
