“…Most monopole antennas commonly refer to quarter wavelengths (λ/4); derivatives of dipoles where one element is folded into the ground (GND) and serves as the second radiator [1] [2]. The first derivatives of the monopole are the inverted-L and inverted-F antennas [3]- [6].…”

The purpose of this work is to design and analyze an s-shaped printed circuit board (PCB) monopole antenna. The antenna was analyzed to operate at a resonance frequency band of 868 MHz; acceptable in 915 MHz as well. The s-shape is selected due to the need of reducing the overall size of the normal monopole antenna. The printed antenna was designed with an approximate overall size of 39 × 56 mm 2 of which the antenna's upper side is 26 × 39 mm 2 while its reference ground board was sized at 39 × 30 mm 2. The antenna is fed by a strip line of 3 × 1.5 mm 2 , in series with a 4.4 pF capacitance and shunt with an 8.7 nH inductance for purpose of antenna's impedance matching with the input. A couple of existing publications showed that PCB antenna is not a new technology; however not an old technology for telecommunication industry. The raised problem by this work was duly solved with HFSS as a tool; excellent results are presented. After duly matching the antenna's impedance with 50 Ω microstrip feed-line, solutions for overall performance were analyzed and demonstrated optimal: radiation patterns were proven omnidirectional, antenna gain optimized. The present antenna prototype's overall dimensions can be readjusted according to any industrial and manufacturing requests.
