In this paper we present a Fabry-Perot type of design, involving a microstrip array covered by a 14??0 ?? 14??0 superstrate that realizes a directivity of 32 dB when excited by an array of 25 microstrip patches. We show that the directivity of the array can be enhanced by an additional 2 dB by using a two-layer superstrate. We present the radiation patterns for the two cases to show that the sidelobe...
A small compact microstrip patch antenna with C-shaped slot is presented. It is developed to operate in the WiMax frequency range of 2.5-2.69 GHz. The antenna presents a size reduction of about 37% when compared to a conventional microstrip patch.
In this paper, a new design of miniature, multiband slot antenna is presented. The slot structure of the proposed antenna is based on the 3rd iteration of the Moore space-filling geometry, which is a closed variant of the conventional Hilbert space-filling curve. The slot structure is constructed on the ground plane side of a dielectric substrate. The slot antenna is fed by a 50 ?? microstrip line,...
