Surface Currents Analysis and Radiation PatternДЇigure 3 shows simulated results of surface current at 4.8 GHz, a Of the antenna increases by 0.1GHz that is, a frequency range ofД¤.18-5.03 GHz substitutes the range of 4.13-4.88 GHz.ДЈ.2. However, as it can be seen from theД¬omparison in Figure 2(a), when sheet metal is added, port impedanceДecreases from 127.3 to 85.1, which ends up with matching Simulation, which leads to fairly fine middle feed, thus port impedance Requirements of omni-directional radiation when designing an antenna in Next to the feeding port at the bottom of the antenna plays a crucial It is worth stressing that the loaded sheet metal (Figure 2(b)) To 5.03 GHz is lower than -10 dB and the reflection coefficient here isД¬alculated when port impedance of the design is 85.1 (FigureДў(a)). Illuminating reflection coefficient for the frequency range between 4.18

With the model simulated by CST Microwave Studio software inДЇigure 1, results are shown in Figure 2 as well as Figure 3, Impacts of Loaded Sheet Metal Next to the Feeding Port Loaded monopole antenna with a skirted dipole (in the upper half ofДЈ.1. The overall antenna is in the form of PCB, regarded to consist of aДoublet antenna (in the lower portion of Figure 1(a)) and an elliptic Parameters of the antenna are as follows. And theД®lliptical monopole is located in the antenna terminal. Jump wires on the back of the slab through the metalized vias. A CPW-fed structure is applied to the design.ДЇurthermore, the metals on the left and right on the front of theДЄntenna (as shown in Figure 1(a)) are connected together by the metallic The blackДЄreas printed on both sides of the dielectric slab are metals (FiguresДЎ(a), (b), (c)). With 1.5 mm thickness, whose dielectric constant er is 4.4. Two-sided printed circuit board (PCB), printed on a FR-4 epoxy substrate Introduction (2) antenna structure (3) simulation analysis (4) testedДЇigure 1 shows the antenna structure. The article is divided into the following five parts: (1) High-gain antenna with its overall omni-directional gain better thanД¤dBi over a frequency range of 4.18 to 5.03GHz (the relative bandwidth By simulating the models builtД«y CST Microwave Studio, we finally got an omni-directional Printed circuits, consisting of a doublet antenna and an elliptic loaded That is, the overall antenna is in the form of Resulting in adverse effects on antenna miniaturization.ДЄ composite dipole planar antenna array with direct feed is Gain and lower electrical length ratio in the polarization direction, Additionally, high-gain omni-directional antennas, which areД«ased on COCO antenna, provide narrow bandwidth, low omin-directional Although these can be reconciled with a means of anДЄrray, it fails to be operated due to its complexity and large However, the antenna radiation pattern bandwidth is relatively narrowДЄnd the gain is low. Of impedance bandwidth, which can generally reach a ratio more than 2 :ДЎ. Initially, ultra-wideband radiating antennaД®lements offer an excellent characteristic of a fairly wide range Together with securing communal applications of antennas in multi-systemДЄs well as serving as an important means of antenna miniaturization.ДЄccording to indexes demanded above, researchers proposed a vastДeal of plans of antenna designs that can be divided into following twoД¬ategories: ultra-wideband radiating antenna elements and highgain The former aims to miniaturizeД¬ommunication systems and the latter accelerates communication rate, Generally, an omni-directional antenna is designed to be higher thanД¤dBi in gain, which accordingly guarantees link gain and beam coverage.ДЄdditionally, an antenna is expected to meet the needs of both The mobile communication of base stations with terminal users. Required to be capable of both miniature and omni-directional, such as High-gain, wide-band and omni-directional, so terminal antennas are Requirements for base station antennas to possess the characteristics of Retrieved from ДЇor point-to-multipoint communication systems, there are common APA style: A composite dipole antenna array with direct feed.A composite dipole antenna array with direct feed.'
