“…The measurement of the proposed CPW antenna in this article has been fulfilled by using the network analyser PNA-X N5247A from agilent technologies and a SMA connector operating until 12 GHz. The return loss has been computed by the two solvers CST and ADS and presented in the the measured one, a good agreement between the three graphs appeared in term of input impedance matching in a bandwidth of 120% from 2.99 GHz to 12 GHz which include the FCC band 3.1-10.6 GHz [18][19][20][21][22][23][24][25][26][27][28].…”

In this study a validated antenna into simulation and through measurement has been described and analyzed. The coplanar waveguide (CPW) technique has been chosen to feed the radiating patch while the two ground planes have been partially designed in the top side of the substrate. The fractal geometry, applied to the circular radiator, has been obtained by merging the circular and rectangular shapes. The fiberglass FR-4, with a single side of 35μm copper thickness, has been used to achieve the antenna material with a permittivity of 4.4, a thickness of 1.6 mm, a loss tangent of 0.025 and an overall dimension of 34x43 mm 2. The proposed CPW fractal antenna has been configured to operate in the frequency range 3.1-10.6 GHz published by the federal communications commission (FCC) as an ultra-wide band (UWB). To calculate the return loss, the gain, the current density and the radiation pattern of the simulated antenna, two electromagnetic solvers have been involved which are the CST microwave studio and ADS. The series of measurement have been performed by using the network analyzer and the anechoic chamber in order to confirm the computed antenna.

“…"For the CST, its tool is based on the FDTD (the finite-difference time domain) method, based on the gridding the spatial and time with same way for the electric and magnetic fields by aligning the E cell with the boundary of the configuration. While the technique behind ADS is the method of moment which is based on the formulating of the unknown current on the radiating patch, the microstrip transmission line and their image on the ground plane by an integral equation" [1].…”

The paper presents the concept of a fully planar treeshaped antenna with quasi-fractal geometry. The shape of the proposed radiator is based on a multi-resonant structure. Developed planar tree has symmetrical branches with different length and is fed by a coplanar waveguide (CPW) with modified edge of the ground plane. The antenna of size 29 mm x25 mm has been designed on Taconic -RF-35 substrate (r = 3.5, tg= 0.0018, h = 0.762 mm). The paper shows simulated and measured characteristics of return loss, as well as measured radiation patterns. The proposed antenna could be a good candidate for broadband applications (for instance: wideband imaging for medical application and weather monitoring radars in satellite communication etc.) Keywords-broadband antenna, fractal antenna, reflection coefficient, defected ground structure, coplanar waveguide I. INTRODUCTION NTENNA (radiator) could be called a main component in wireless systems, because based on its performance is easily to estimate and analyze effectiveness of the wireless communication around the world. Radiator is a transducer which task is carrying the current. The antenna, in accordance with the general definition, is used to convert radio frequency (RF) fields into alternating current or vice versa. There are both receiving and transmission antennas for sending or receiving radio transmissions [2]. Therefore, the antennas are very important in wireless systems, because they transmit and receive the information via the air [2,11].Since the beginning of the 21st century, the design and analysis of antennas and antenna arrays for broadband and Ultra WideBand systems (UWB) are characterized by growing interest. Various applications of electronic systems require designers to pay attention on different properties of antennas, depending on the criterion chosen, for example: size, bandwidth, radiation pattern, gain, efficiency and impedance matching. In world literature, the prevailing proposals include single radiators in a wide range of shapes: from the classic ones (rectangle, triangle, circle) to fractal (curves filling space) and nature shapes (flower, tree); there are also examples of large antenna arrays, but there are definitely fewer ideas [8,9,10].The microstrip antenna can be a good idea for wideband or UWB system, because it is characterized by the small profile, easy to fabricate and very low cost of fabrication. The microstrip technology consists of two main parts on a dielectric substrate. They are: microstrip transmission line and ground plane which are made of conducting material on one side or on the both sides [7].The article briefly reviews a couple of different antennas for the broadband applications, constructed over the last decade (2008 -2018). It is summarized in the form of project of a M. Malinowska and M. Kitliński are with

“…Unlike conventional antennas [1][2][3][4][5][6][7][8] which has a fixed operating frequency or pattern types, reconfigurable antennas have the ability to varying its operating frequencies and also radiation pattern to satisfy the modern communication systems. Most of the antennas in [1][2][3][4] have a wideband operating frequency, using a mictrostrip patch antenna design to operate in Ultra-wide band (UWB) frequency range. Meanwhile, reported antennas in [5][6][7][8] only can operate in multiband frequency.…”

Wideband-multiband reconfigurable elliptical monopole antenna is investigated in this paper. By having conventional elliptical monopole antenna, wideband operating frequency is obtained. With the combination of dual pairs of slotted arms and a band-pass filter on the ground plane of the elliptical monopole, multiband is achieved. Dual-band operating frequencies at 1.6 GHz and 2.6 GHz while wideband operates from 3.35 GHz to 9 GHz. Therefore, wide range of wireless communication systems is obtained from the proposed antenna to support the multiband mode (i.e. GPS and LTE) and UWB systems. Frequency reconfigurable is achieved by controlling the switches integrated on the antenna structure. Simulated results of reflection coefficient, radiation patterns and gain performance are presented. The proposed antenna design is suitable candidate for different wireless communication applications.
