AbstractA multi-input multi-output (MIMO) antenna is designed and discussed for multi-band applications. The constituent antennas are composed of four L-shaped elements and a ground plane. When placed beside each other to form a MIMO antenna, a T-bar shaped parasitic structure is also embedded between the antennas on the backside of the substrate to increase the inter-element isolation. The triple-band performance of the antenna is observed at 2.15–2.73 GHz, 3.1–3.9 GHz, and 5.04–6 GHz. The isolation level of more than 20 is seen over the operating frequency range. The fabricated prototype of the MIMO antenna size is very compact (20 × 40 mm), printed on the FR4 substrate. Based on simulation and experimental results, the proposed design is useful for WiMAX and WLAN applications.

Feeding Techniques

In this study, a triple-band suspended microstrip antenna with symmetrical U-slots is proposed for modern wireless communication systems. The antenna is specifically designed to acquire application in WLAN and WiMAX communication. Symmetrical U-slots in the radiator patch increase the number of resonances and improve the gain response. An appropriate air height was maintained between the ground plane and the radiator patch layer for improving bandwidth operation. The impedance characteristics of the antenna are enhanced using probe feeding techniques. The proposed compact antenna is designed on a single dielectric substrate of (30×25×1.56) mm3 . Parametric analysis of the proposed structure has been realized using IE3D software. This prototype exhibits maximum impedance bandwidth of 750 MHz and gain response of 7.28 dBi. The performance of the structure at three resonating bands i.e., at 3.3 GHz, 3.78 GHz and 5.3 GHz facilitate it to be applicable for WLAN/WiMAX systems.

Antenna Characteristic

This article gives brief view of UWB microstrip antenna characteristic without a slot and with a triangular slot on the patch of the MSA. Nowadays UWB antenna is a must for wireless communication with the narrow pulses in the series of nanoseconds, for the application of ultra- wideband in frequency domain for very short distance and minimum power densities. The research in this field has become more sought-after and therefore the demand on UWB microstrip antenna is rising rapidly. The currents along the verge of the slot initiates additional resonance, it concords with the main patch resonance, which result in the production of overall frequency response characteristics, ultimately leads to wideband. Thus a crisp novel ultra-wideband configuration with and without a triangular slot have been proposed. And the radiation is in the broadside of antenna with small variation along the entire bandwidth. Thus improving the robustness of the MSA and cost reduction. Due to the potential of UWB antennas,they are significant to improve the performance of wireless communication systems. The MSA (microstrip antenna) is designed with FR-4 substrate. There is increase in bandwidth due to the introduction of triangular slot in the patch and the variation in the antenna parameters are briefed below. This document can be used as guide to design small MSA for mobile communication.

A novel compact triple-band slot antenna is proposed for WLAN/WiMAX applications. With the use of three L-shaped slots and an open-ended slot on the ground plane, three resonant modes centered at 2.4/3.5/5.8 GHz are excited. These modes cover the standards of 3.5 GHz WiMAX and 2.4/5.8 GHz WLAN, three useful frequency bands for present wireless communication systems. The proposed antenna fed by L-shaped microstrip line has a small overall dimension of16×30 mm2. The numerical and experimental results show that acceptable radiation characteristic is obtained over the operating bands.
