Pattern reconfigurable antennasBeam switchingDeployable antennaThis paper presents a novel deployable antenna design with reconfigurable radiation patterns suitable for various indoor Internet of Things (IoT) applications. Inspired by origami, the antenna comprises a central monopole patch housed on a magic ...
In this article, a novel microstrip Yagi antenna under operation of the TM20 mode is proposed to obtain an enhanced end-fire radiation pattern. First, a two-element microstrip Yagi antenna is theoretically analyzed under different dimensions of the parasitic element. The results demonstrate that ...

Yagi antenna radiation pattern The antenna can be optimised to either reduce radiation in the reverse direction by altering the length and spacing of the reflector or it can be optimised to produce the maximum level of forward gain. Unfortunately the two conditions do not coincide exactly and a...
The optimized design shows a significant improvement in the radiation pattern. Higher directivity is achieved in the desired direction toward zenith. The back lobe is small, resulting in a good front-to-back ratio for this antenna. Calculate the directivity at zenith, front-to-back ratio, and ...
pattern reconfigurable; planar antenna; Yagi-Uda; PIN diodes ABSTRACT A pattern reconfigurable planar Yagi-Uda antenna is presented which operates around 1.5 GHz. The pattern reconfigurability consists in changing the end-fire main beam to opposite directions. It is achieved by switching the reflector...
Radiation Pattern The directional pattern of the Yagi-Uda antenna is highly directive as shown in the figure given below. The minor lobes are suppressed and the directivity of the major lobe is increased by the addition of directors to the antenna. Advantages The following are the advantages of...

Plot Radiation Pattern at Design Frequency Prior to executing the optimization process, plot the radiation pattern for the initial guess in 3D. pattern(yagidesign,fc); This initial Yagi-Uda antenna does not have a higher directivity in the preferred direction, meaning at z...
If the electrical length of the parasitic element is shorter than the driven element, the radiation pattern reversed and the parasitic element became a Director (D) always in the two-elements of the Yagi antenna. FAQ's:what does the antenna difference between Yagi-Uda and Yagi? A television ...
