Abstract

A compact monopole antenna for smart meters in Industrial Scientific and Medical (ISM) band 900MHz is developed in this paper. The antenna was built in low-cost material (FR4), with spirals in PShape, and a total area of 4.32 cm2. The monopole antenna has broadband characteristics, however, the use of a spiral in P-Shape provides a reduction of the bandwidth, making it operate in narrowband. The P monopole antenna presents good relation between simulated and measured results, a difference of 0.32 %, measured bandwidth of 32MHz (896 - 928 MHz), covering the ISM band 900MHz (902 - 918 MHz), omnidirectional radiation pattern, without secondary lobes, with simulated HPBW of 107 degrees, the maximum gain of 2.29 dBi, and current density of 387.19A/m2.
