The irregularity has been very attractive to the antenna and packaging engineers. More specifically, the self-similarity has inspired many researchers to use them for broadband designs, due to the fact that a fractal antenna is a repeated shape in different scales, which can be interpreted as a multiscale (“multi-wavelength”) radiator. In addition to this, the space filling property seems to be...

it is shown how the radiation characteristic of a patch antenna can be manipulated by a small number of normally magnetized ferrite disks inserted in the resonant region of the patch. It is shown that a oneand dual-band circular polarized microstrip antenna can be obtained by taking advantage of the interaction of the antenna cavity field with the magnetized ferrite disks. . The dependence of t...

A novel printed octagonal fractal microstrip antenna with semi-elliptical ground plane is presented for ultra wide band applications. The proposed antenna has a compact size of 20×20×1 mm³. The measured result of the antenna exhibits the ultra wide band characteristics from 2/9 to 14/2 GHz. In this paper, reducing antenna’s size by 35%, the same results were achieved, while small dimension frac...

A miniaturized new topology of the planar monopole antenna using a Magneto-Dielectric Material (MDM) is proposed in this paper. The element realized by introducing slots partially covered MDM. We optimized and modified MDM dimensions to enhance impact material on antenna, including its structure. This shows miniaturization rate 60% antenna’s height (51 cm 20 cm) covering only 5% surface measure...

The development and utilization of wearable antennas has grown rapidly in recent years for application in the miniaturization of wireless communication devices. The main advantage of wearable antennas is that they are designed as elements of clothing able to transmit or receive wireless signals. The wearable antenna system plays an important role in many fields, including tracking and navigatio...

A new miniaturized dominant mode leaky-wave antenna is proposed. This antenna is a transmission line structure with radiating wavenumber increasing from negative to positive values, providing backward to forward scanning capability as frequency is increased. The antenna profile is designed based on microstrip technology using balanced composite right left handed transmission lines (CRLH TL) app...

The demand for small wireless telecommunications modules that can access the IMT system has increased and their use has proliferated to the remote control of applications such as controlling stock and verifying purchases for vending machines, managing taxi operations, reading of meters, and managing delivery trucks. The IMT system mainly uses the 800 MHz to 2 GHz frequency band. We focus on act...
