Abstract
The propose of this paper is to design the circularly polarized antenna for mobile base station, using a curved strip dipole associated with U-shaped reflector and multi-layer metallic rod elec-tromagnetic band gap (EBG). It can be used to simplify the single feed system of an antenna. The advantages of this proposed antenna are easy fabrication and installation, high gain and light weight. Moreover, it provides a sectoral radiation pattern, a main beam having a narrow beam width in the vertical direction and wider beamwidth in the horizontal direction, which are appro-priate for mobile phone base station. The half-power beam in the H-plane and E-plane are 60 and 14.4 degrees, respectively. The antenna is designed and analyzed by using a computer simulation technology (CST). In addition, S11, axial ratio, radiation pattern and gain are displayed. The designed technique could be confirmed by a measurement resulting from prototype antenna corresponding to simulation results. The proposed antenna has a bandwidth covering the frequency range of 1870 - 2170 MHz, and the gain of the antenna increases up to 15.11 dBi.

The resonant EBG technology has been used to be a reflector for directive gain increment by utilizing the good performance of the mushroom-like EBG structure, which is capable of providing a constructive image current within a certain frequency band
When wide beam curved strip dipole is appropriated located horizontally on a resonant EBG reflector, high directive gain can be obtained of 7.6 dBi for RFID reader

There is an interest in the dipole antenna in wireless communication systems because of its broadband characteristics, elementary structure and simple concept [2]-[4]. The dipole antenna extensively used in practical is S-shaped dipole antenna [5]. The dipole is bent into a V-shape to achieve the maximum gain when it is properly aligned with the curvature of the earth [6]. The dipole antenna has low gain and its radiation pattern is an omni-direction. This argues that, if we can design the antenna to increase a predefined directive gain, it will have more efficiency for field radiating
