In this paper, a broad bandwidth and high gain rectangular patch antenna using planar-patterned metamaterial concept is proposed. Top patch has seperated micro triangular patterns with periodic gaps while the ground plane etched with crossed strip-line gaps. The patterned metal patch and ground plane form a coupled capacitive-inductive circuit of negative index metamaterial. Extended bandwidth from...
A single-feed circularly polarized (CP) patch antenna loaded with metamaterial (MTM) for broadband operation is presented. The antenna is designed with a truncated corner square patch placed between a lattice of 4 × 4 periodic metal plates and the ground plane. The antenna with an overall size of 32 mm × 32 mm × 3 mm resulted in a |S11| <–10 dB bandwidth of 4.70–7.48 GHz (44%), and a 3-dB AR bandwidth...
In this paper, the broadband metamaterial antenna utilizing zeroth-order resonance (ZOR) mode and TM010 mode is presented. Employing the folded parasitic patch, the frequency of TM010 mode can simply be down-shifted to the frequency of ZOR mode without changing the size of the antenna. Therefore, the metamaterial patch antenna operates at two modes. As a result, the 10dB fractional bandwidth of an...
A slotted microstrip patch antenna is designed with Electromagnetic Band gap (EBG) structures. The performance parameters of the presented antenna are then compared with the conventional patch antenna. It is realized that there is a significant increase of bandwidth and better suppression of harmonics than the normal patch antenna. This antenna is thus operating in the frequency band 5 - 6 GHz which...
A novel rectangular patch antenna was specifically designed using planar-patterned metamaterial concepts. The patterned metal patch and finite ground plane form a coupled capacitive-inductive (C-L) circuit of negative index metamaterial. For the wideband, high efficiency, low loss and low VSWR, the novel type of antenna is used to design meta array, the array still have bandwidth significantly broadened...
In this paper we present results on miniaturization of a wideband stacked patch antenna. In particular, using numerical simulation we demonstrate that a thirteen percent in physical size reduction can be achieved in a wideband stacked patch antenna using synthetic reactive elements namely the split-rings resonators (SRRs) while maintaining a relatively large bandwidth of eighteen percent. The calculated...
