Bandwidth enhancement for microstrip patch antenna using stacked patch and slot [PDF]

open access: yes, 2009
Small size wideband microstrip patch antenna with slot in ground plane and stacked patch fed through microstrip line is presented. By inserting slot on ground plane and stacked patch supported by wall, the bandwidth can improve up to 25% without ...

Space-Time Index Modulation

open access: yes, 2016
In this paper, we present a new multi-antenna modulation scheme, termed as {\em space-time index modulation (STIM)}. In STIM, information bits are conveyed through antenna indexing in the spatial domain, slot indexing in the time domain, and $M$-ary ...

Design and research of single‐sided slotted waveguide antenna with a large beam declination

open access: yesIET Microwaves, Antennas & Propagation, 2021
The slot of the conventional longitudinal slot antenna is alternately opened on both sides of the broadside. A novel single‐sided slot array with a large‐declination (biased towards the load) is proposed, in which the slots are only biased to the same ...

Design of Compact Beam-Steering Antennas Using a Metasurface Formed by Uniform Square Rings

open access: yesIEEE Access, 2018
In this paper, we propose two designs of slot-fed metasurface antenna for beam steering applications. Both designs have the same two-layer stacked configuration consisting of either a single-slot or a double-slot radiator and a metasurface superstrate ...
