The\nsubstrate used is single-sided glass-reinforced epoxy and the an-\ntenna dimensions are 37\u00d737\u00d71.6 mm 3 . The antenna is compact,\nlow-profile, circular polarized having an ARBW of around 500\nMHz (center frequency 4.6 GHz). A coplanar waveguide (CPW)\nfed monopole antenna is used for excitation of the modified-square\nslot antenna that incorporates quarter section of circular symmet-\nrical patches on the four corners. A stub orthogonal to the CPW\nfed monopole capacitively tunes the low Q mode as identified by\nCMA technique to shift to a lower frequency to create degenerate\nmodes in military band for circular polarization generation. The\n3-dB AR bandwidth of the antenna is in the frequency range 4.43-\n4.9 GHz and measured value of impedance bandwidth is 3.33 GHz.\nThe fractional ARBW and impedance BW are 10.07 % and 61.6 %\nrespectively. The peak antenna gain in the CP frequency band is\n3.75 dBic. The proposed antenna exhibits good polarization purity,\nthe minimum axial ratio is 1.38 at 4.6 GHz. The broad circular\npolarized antenna is suited for military applications covering the\nfrequency range 4.43-4.9 GHz.<\/h5>\n<h5>Full text:  <a class=\"fas fa-file-pdf\" href=\"https:\/\/els-journal.net\/wp\/wp-content\/uploads\/2023\/01\/2022-26-2-02.pdf\" target=\"_blank\" rel=\"noopener\"><\/a><\/h5>\n\n\n\n\n<a target=\"_blank\" href=\"http:\/\/www.scopus.com\/inward\/citedby.uri?partnerID=HzOxMe3b&#038;doi=10.53314\/ELS2226046S&#038;origin=inward\" ref=\"scopus-citedby\" rel=\"noopener\"><image src=\"http:\/\/api.elsevier.com\/content\/abstract\/citation-count?doi=10.53314\/ELS2226046S&#038;httpAccept=image%2Fjpeg&#038;apiKey=87124910cd33413b75b0a6f4e70d58bd\" border=\"0\" alt=\"cited by count\"\/><\/a>\n\n\n\n\nGoogle Scholar Citations <a target=\"_blank\" class=\"fas fa-external-link-alt\" href=\"http:\/\/scholar.google.com\/scholar?hl=en&#038;lr=&#038;cites=http:\/\/dx.doi.org\/10.53314\/ELS2226046S\" rel=\"noopener\"><\/a>\n\n\n\n\n<center> <span class=\"__dimensions_badge_embed__\" data-doi=\"10.53314\/ELS2226046S\" data-style=\"small_circle\"><\/span> <\/center> <script async src=\"https:\/\/badge.dimensions.ai\/badge.js\" charset=\"utf-8\"><\/script>\n\n\n\n\n<center>Google Scholar Citations <a target=\"_blank\" class=\"fas fa-external-link-alt\" href=\"http:\/\/scholar.google.com\/scholar?hl=en&#038;lr=&#038;cites=http:\/\/dx.doi.org\/10.53314\/ELS2125065A\" rel=\"noopener\"><\/a><\/center>\n\n\n\n\n<a target=\"_blank\" href=\"http:\/\/www.scopus.com\/inward\/citedby.uri?partnerID=HzOxMe3b&#038;doi=10.53314\/ELS2226046S&#038;origin=inward\" ref=\"scopus-citedby\" rel=\"noopener\"><image src=\"http:\/\/api.elsevier.com\/content\/abstract\/citation-count?doi=10.53314\/ELS2226046S&#038;httpAccept=image%2Fjpeg&#038;apiKey=87124910cd33413b75b0a6f4e70d58bd\" border=\"0\" alt=\"cited by count\"\/><\/a>\n\n\n\n\n<center><span class=\"__dimensions_badge_embed__\" data-doi=\"10.53314\/ELS2226046S\" data-style=\"large_rectangle\"><\/span><\/center><script async src=\"https:\/\/badge.dimensions.ai\/badge.js\" charset=\"utf-8\"><\/script>\n\n\n","protected":false},"excerpt":{"rendered":"","protected":false},"author":1,"featured_media":0,"parent":549,"menu_order":0,"comment_status":"closed","ping_status":"closed","template":"","meta":{"footnotes":""},"class_list":["post-558","page","type-page","status-publish","hentry"],"_links":{"self":[{"href":"https:\/\/els-journal.net\/wp\/index.php?rest_route=\/wp\/v2\/pages\/558","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/els-journal.net\/wp\/index.php?rest_route=\/wp\/v2\/pages"}],"about":[{"href":"https:\/\/els-journal.net\/wp\/index.php?rest_route=\/wp\/v2\/types\/page"}],"author":[{"embeddable":true,"href":"https:\/\/els-journal.net\/wp\/index.php?rest_route=\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/els-journal.net\/wp\/index.php?rest_route=%2Fwp%2Fv2%2Fcomments&post=558"}],"version-history":[{"count":14,"href":"https:\/\/els-journal.net\/wp\/index.php?rest_route=\/wp\/v2\/pages\/558\/revisions"}],"predecessor-version":[{"id":641,"href":"https:\/\/els-journal.net\/wp\/index.php?rest_route=\/wp\/v2\/pages\/558\/revisions\/641"}],"up":[{"embeddable":true,"href":"https:\/\/els-journal.net\/wp\/index.php?rest_route=\/wp\/v2\/pages\/549"}],"wp:attachment":[{"href":"https:\/\/els-journal.net\/wp\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=558"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
