Low Profile Tri-Bands Antenna for Wireless Applications

A low-profile compact antenna with triple band operation for wireless security, WIMAX, and WLAN applications is proposed in this paper. The antenna has a simple structure with an overall area of 40 x 40 mm2. Analysis and simulation of the proposed antenna is done by using the full 3D electromagnetic simulation software CST STUDIO SUITE. The performance of the proposed antenna was evaluated by using the reflection coefficient, the radiation pattern, and the gain.
