Abstract

This research proposes four antenna designs. There are microstrip array patch rectangular (1x2 and 1x4) and microstrip array patch triangular (1x2 and 1x4). The most optimal antenna for use at a working frequency of 2,3 GHz is the antenna microstrip array patch rectangular 1x4 using the array shifting structure method. This antenna has success in forming two-beam (reconfigurable beam) arrangements in one antenna, each beam showing a graphical representation of the antenna alignment in the space plane including the propagation of the electric field (E) and the propagation of the magnetic field (H). The antenna parameter values for the left beam are: VSWR 1.27, return loss -18.36 dB, bandwidth 50 MHz, gain 3.47 dB, beamwidth azimuth (theta 90° = 115°, theta 170° = 145° and theta 270° = 115°) and a directional radiation pattern. While the antenna parameter values for the right beam are: VSWR 1.23, return loss -19.46 dB, bandwidth 60 MHz, gain 3.64 dB, beamwidth azimuth
(theta 90° = 100°, theta 170° = 150° and theta 270° = 100°) and a directional radiation pattern. Antenna design and simulation using Ansoft HFSS software version 15.

Urgent Regarding ISSN Update

Announcement Date: April 20, 2021

Dear Authors and Researchers,
We would like to inform you that the U.S. ISSN Center at the Library of Congress has confirmed that the correct ISSN number of the Journal Psychology and Education is ISSN 1553-6939. This ISSN is to be used instead of ISSN 0033-3077 which is the ISSN that belongs to the former title, “Psychology.” Each time a journal undergoes a major change of title a new ISSN is assigned. Psychology and Education also has been assigned a Linking ISSN (ISSN-L). The ISSN-L is available for use when there is a need to identify and link to a continuing resource without regard to format, for example in services such as OpenURL, library catalogues, search engines or knowledge bases. The next issue of Psychology and Education will be published with ISSN 1553-6969. But the previous ISSN will be also available in the ISSN Portal to retrieve the record for Psychology because it remains the identifier for the former title Psychology and the articles published under that title.
