Thus, it can be a good choice for many applications in which small dimensions matter such as military and satellite communications. In addition to that, the antenna had total dimensions of . Furthermore, the antenna had almost an omni-pattern in the E plane and bidirectional pattern in the H plane at low frequency. The antenna operated in a wide BW from 6 GHz to 18 GHz with . Many researchers had improved the parameter result to give a better performance and efficiency of the patch antenna design. An MTM-based low-profile antenna was designed for UWB applications . It was observed that the antenna attained the maximum radiation efficiency of 94% at 3.5 GHz. The total dimensions of the proposed square monopole antenna were which assisted in having a wide BW over the band and a low-frequency edge lower than 2 GHz. A planar MTM structure was integrated with a low-profile high-gain microstrip patch antenna for UWB application . After the simulation, the antenna’s characteristics were measured, and its performance was investigated. This page covers different types of antennas used in wireless communication.The basics and types of antennas include horn antenna,parabolic antenna,helical antenna,slot antenna,dielectric antenna,patch antenna,phased array antenna,dipole antenna,directional antenna,folded dipole antenna,ground plane antenna,YAGI antenna,Log periodic antenna etc. The TSA antennas were applied for UWB communication applications since a long time ago. A compact and low-profile flexible wearable antenna was designed to integrate with electronic components . This UWB antenna was simulated for WBAN as a revolution of the sensor network (Figure 16) . There are several types of antennas and each literature work has its own classification of antennas. It concludes research insight for future research directive suggestions such as how loading can affect and improve the BW for wide-band and UWB antennas and how it can keep the antenna dimensions miniaturized while the antenna characteristics are not affecting a lot. Hence, many techniques could be applied to filtering these bands like making notches on the patch or the GND layer. is not discussed here even though there is an antenna involved (usually with the operator, who receives the signal with the help of antenna and transmit them through a co-axial cable). It consisted of a circular ring patch with inner and outer radii of and , respectively, and then fed by a microstrip line. Thus, the proposed antenna had a broad BW from 3-12 GHz and FBW of 119%. Diy Digital Clock Kits Therefore, the proposed antenna illustrated promising results in free space and on body integration even under harsh conditions of bending and it proved that it was a good choice for indoor UWB communication applications. The antenna achieved a wide BW of 3.1 GHz to 10.6 GHz as lower and higher ends of the UWB band. In each step of the design, the radiation modes were investigated to obtain proper excitation (Figure 7) . The antenna’s BW increased by optimizing the physical dimensions of the radiator. To improve the BW further, two semicircular slots and four quasitriangular slots were cut from the patch. The maximum gain and radiation efficiency of the antenna were 7.1 dBi and 91%, respectively. RF communications incorporate a transmitter and a receiver. The electromagnetic performances, the dimensions, and the materials, as well as the design solutions useful to improve the antenna bandwidth of monopole (2D and 3D profile), printed planar antennas, metamaterials, tapered and wide slot antennas, and elliptical patch printed and wearable antennas were presented here. The far-filled characteristics of the antenna were investigated for both in-phase and out-of-phase.
