Abstract

<abstract abstract-type="main"> <title>ABSTRACT</title> <p>In this article, compact antenna with high gain and circular polarization (CP) for WiMAX applications is noticed. Using metamaterials with negative permittivity and permeability improves the antenna parameters; thus, the prototype antenna is designed based on metamaterial composite right‐/left‐handed to achieve CP and compact size. The final antenna has directional pattern and high gain with CP at 3450 MHz. The antenna gain is 8.28 dBi. The size of prototype patch antenna is 30 <inline-formula><alternatives><inline-graphic mimetype="image" xlink:href="ark:/27927/pgh2wq8nzjm" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /><mml:math display="inline" altimg="urn:x-wiley:08952477:media:mop28846:mop28846-math-0001" overflow="scroll" xmlns:mml="http://www.w3.org/1998/Math/MathML"><mml:mo>×</mml:mo></mml:math></alternatives></inline-formula> 30 mm². It is designed and fabricated on Taconic TLY‐5, Laminate substrate with ε_r = 2.2 and thickness of 1.6 mm. It is simulated by CST microwave studio and HFSS. Also, equivalent circuit and experimental results are presented and compared here. © 2015 Wiley Periodicals, Inc. Microwave Opt Technol Lett 57:357–360, 2015</p> </abstract>
