Simple Approach to Bandwidth Enhancement Of Compact Pifa For Wireless System Applications

Bandwidth is a critical parameter that must be considered in the design of electrically small antennas for compact wireless system. In order to overcome the demerit of narrow bandwidth, a simple method of bandwidth enhancement through parametric study of PIFA is proposed. The PIFA understudied was designed and simulated by the use of theoretical equations based on transmission line model and High Frequency Structural Simulator (HFSS) respectively. It has initial bandwidth of The study reveals that by reducing the size ratio of the planar element (radiating patch) of PIFA, bandwidth enhancement of was achieved. Increasing the distance between short plate and feed gave rise to increment in bandwidth while increasing the length of ground plane while keeping the width of ground plane constant enhanced bandwidth by . The designed compact PIFA of patch size can be employed in wireless systems such as cell phone and implantable medical devices .

In this paper, a simple method of enhancing the bandwidth of the Bell-shaped UWB Antenna for indoor localization systems is proposed. Therefore, a modified version of the bell-shaped Ultra-Wide Band (UWB) antenna for indoor localization systems is presented. The proposed antenna is printed on a low-cost FR-4 substrate of 21×27×1.6mm3 size. It is composed of a bell-shaped radiating patch and a multi-slotted ground plane. The measured results show that the proposed antenna has an impedance bandwidth of about 11.2GHz ranging from 3.16GHz to 14.36GHz at S11<−10dB. Compared to the original version, an enhancement of about 5.56GHz in the measured impedance bandwidth was observed.

Narrow Bandwidth

Microstrip patch antenna (MPA) is suitable for different applications in wireless communications. MPA suffers from low gain and narrow bandwidth. In this paper we improved its bandwidth by inserting multiple slots in its ground plane. We used FR-4 substrate to design this antenna. The dimensions of this antenna are 60mm and 80mm. The dielectric constant is equal to 4.4 and the height is 1.6mm. We inserted up to 12 slots in ground plane with 1mm width. The spacing between slots is 3mm slots were arranged parallel to the feeding line. Simulation was done using HFSS simulator.

Small Antenna

In this paper, an electrically small, planar antenna with broad side radiation pattern is presented. The design contains a dipole and a segmented circular loop which works equivalent to that of a magnetic dipole. A circular patch with slots is used to provide impedance matching. In general, electrically small antennas suffer from narrow bandwidth. In this paper, the reconfigurability of the small antenna for two different applications, 1.5GHz and 2.4GHz, is discussed. This reconfigurability was achieved by using a BAR 64-03W pin diode to adjust the resonant frequency. Two reconfigurable frequency bands were achieved at 1.5GHz and 2.4GHz with broad side radiation patterns.

Meander Line

Meander line antenna (MLA) is an electrically small antenna. Electrically small antennas pose several performance related issues such as narrow bandwidth, high VSWR, low gain and high cross polarization levels. In this paper overview on properties, parameter consideration and design of MLA is proposed. The proposed antenna is designed for USB based application. The antenna performance parameters are optimized to achieve reasonably wide impedance bandwidth, high gain, VSWR < 2 and an Omni directional radiation pattern. Moreover, the current distribution and the effect of the ground plane size on the altered MLA are discussed in this paper.

Available Volume

In view with the latest technologies, compact device sizes had become a greater focus in industry because of which the demand for small antenna escalates. But electrically small antennas have high quality factor because of which the gain decreases. Therefore, an antenna was designed to improve the gain using the meander line concept based on the ground plane effect. A finite ground plane affects the resonant frequency and as the ground plane size increases, the resonant frequency decreases. By using a truncated ground plane, the antenna efficiency, gain and radiation pattern are improved. The antenna design had been modified based on another important concept of efficiently occupying the available volume. The antenna was designed on a cubic configuration and by using the two general techniques of modifying the geometry and truncating the ground plane, the gain of the antenna had been improved from 7.05dB to 8.03dB.
