Antenna characteristics are chosen according to the features determined
by the systems where they will be used. While some systems require a
very narrow bandwidth, others may operate with a much wider bandwidth.
Some techniques used for increasing the bandwidth of a given antenna
have considered mechanical adjustment of the air layer thickness, wit...

... simple way for realizing a short in a patch antenna was used by inserting a via hole joining the patch metallization and the ground plane at the desired location 1 . Simulations of the antenna array were also performed considering a rectangular ground plane separated from the array in the same way as in figure 1, by a distance equal to 3h. The pentagonal antenna array with an external ring is shown in figure 4. In figure 5, the gain of the pentagonal patch antenna array is presented under linear polarization. ...

This article presents a novel single-feed circularly polarized patch antenna for dual-band (2.6 and 3.4 GHz) applications. Details of the design procedure and design considerations of the proposed antenna are described. The novelties of the proposed antenna are counted by (i) a meaningful Jia-shaped patch used as the primary radiator; (ii) a 3D L-s...
