I. Introduction
In latest wireless communication technology upgrades the high performance of the antenna like low profile, size miniaturization and radiation characteristics [1]. In this process, designing a dual -band antenna is a key component for realizing the radiation characteristics of the proposed antenna [2]. It offers the better size reduction, which is compared with conventional planar antennas for GPS/ WLAN applications [3]. The ACS-fed has been yielded to acquire impedance matching and offers dual band radiation. The designed loop resonator has significant advantages of compact size, cost effective including better reflection coefficient characteristics [4]. The rectangular loop is used to build the dual - band (lower and upper) resonances with suitable radiation characteristics [5]. The designed antenna has a compact size of 21.57mm × 25.62 mm × 1.6mm which is fabricated on a inexpensive FR-4 (Flame Retardant-4) substrate with a 4.4 dielectric constant [6].
