A dual-band antenna by use 2 × 2 patch array with L-slot is presented for simultaneously worldwide interoperability for Microwave Access (WiMAX) and wireless local area network (WLAN) application. This 2 × 2 Patch Array with L Slot Antenna is targeted to achieve the gain more than 2 dB for both frequencies by using array technique design. The antenna design structure has been modified by adding a...
In this paper, a very small 2.45 GHz printed antenna suitable for WLAN application is proposed. In order to decrease the size of the antenna, multi-layer substrate and shorting plate method are used. A microstrip line which can lead to a good impedance matching and four pairs of slot are used to obtain acceptable value of return loss at the desired frequency. These techniques are used as a mean that...
In this paper, a compact printed antennas with a band-stop characteristic for ultra-wideband application are proposed. The dual-oval shape is introduced to reduce the size of the dimension, thus make it more compact. In order to increase the impedance bandwidth of the proposed antenna, a partial ground and circular slot are used. By attaching an inverted Y-shaped open-circuited stub in the circular...
This paper describes the design and simulation of Sierpinski Carpet Fractal Planar Inverted F Antenna (PIFA) for WLAN and HiperLAN applications. Simulation of antenna is carried out using CST software; on a FR4 board with a substrate thickness of 1.6 mm and relative permittivity of 4.7. The antenna achieved satisfactory 10-dB impedance bandwidths, between the frequencies of 2341-2812 MHz and 5360-6154...
