In this paper the effects of parameters of a square loop frequency selective surface to the resonance frequency is studied. Side length of the square loop, width of the conducting patch, thickness and the substrate are varied and their effects on resonance frequency evaluated via a Finite Integration Technique (FIT) based simulator. The absorption and reflected characteristics and the transmiss...

This paper presents a compact dual-band slot antenna for 2.4/5 GHz WLAN applications. The radiating elements of the proposed antenna are composed of a square ring slot and a circular ring slot, operating at 2.4 GHz and 5 GHz bands respectively. The antenna size is very compact (40 mm × 40 mm × 1 mm), and can be integrated easily with other RF front-end circuits. It is demonstrated that the prop...

This paper presents an investigation of split ring resonator (SRR) parameters on a coaxial-fed monopole antenna. The adding of SRR slot can create a notch in the result of coaxial-fed monopole antenna design. Thus, this paper aims to investigate the effect of changes to the outer ring radius and slit cut width of the SRR slot. All antenna designs and simulations involved are drawn and simulated...

This letter compares the 3 dB axial ratio (AR) bandwidth (BW) of transmission mode single-screen linear-to-circular polarisation convertors based on three different slot topologies. Using a conventional centre-connected cross-slot arrangement as baseline, we show that significant performance improvement can be achieved by creating more elaborate design with unit cells composed multiple unequal ...
