In this paper, the study of shell and body tissue simulating liquid (BTSL) thickness and its effects on capsule antenna performance at 2.45 GHz were presented. Two simulation setups which consists two different sets of shell and BTSL position near the capsule antenna were used in the simulation process. The reflection coefficient, directivity, gain and efficiency performance in those simulation setups...
In this paper, the study of shell and body tissue simulating liquid (BTSL) effects on compact peanut-shape antenna performance that operate at frequency 2.45 GHz are presented. Two simulation setups which consist of eight different types of simulation were used in the simulation process. Reflection coefficient, bandwidth, radiation pattern and directivity in those simulation setups are determined...
In this paper, the Specific Absorption Rate (SAR) inside the head due to metallic spectacle is investigated. Computer simulation using CST Microwave Studio is used in this investigation. A dipole antenna operated at 900MHz for GSM application is used in the simulation model represent as a radiation source from mobile phone. In parametric studies the maximum 3D gain of dipole plotted by varying its...
In this paper, a very small 2.45 GHz printed antenna suitable for WLAN application is proposed. In order to decrease the size of the antenna, multi-layer substrate and shorting plate method are used. A microstrip line which can lead to a good impedance matching and four pairs of slot are used to obtain acceptable value of return loss at the desired frequency. These techniques are used as a mean that...
A simple block hand model with the size of an adult Malaysian hand is suggested to substitute the existing hand phantom of European size. The hand is set up with a Standard Anthropomorphic Mannequin (SAM) head and a candy bar mobile phone operating at GSM900/1800 using Planar Inverted-F antenna (PIFA). Both hands use the same dielectric properties of CTIA hand phantom. The result gained from simulating...
In this paper, 2.45 GHz small printed antenna suitable for WLAN-band application are proposed. In order to decrease the size of the antenna, multi-layer substrate and shorting pin method are used. Partial and slitted ground methods are used to increase the impedance bandwidth of the antenna. This antenna shows an omni-directional radiation pattern similar to that of a monopole antenna.
A candy bar mobile phone with Planar Inverted-F Antenna (PIFA) operating at 900 MHz and 1800 MHz is simulated with two models of quasi-block hand — homogeneous and inhomogeneous. Maximum Specific Absorption Rate (SAR) is investigated by using Standard Anthropomorphic Model (SAM) hand phantom properties in comparison with the properties of human skin and bone towards the models. Dimension of the quasi-block...
The investigation on the changes of Specific Absorption Rate (SAR) inside the head due to metallic straight pin with simple braces added is presented in this paper. The finite integration in time domain (FIT) computer simulation technique was used in this investigation. The head is irradiated by dipole sources in front of the Specific Anthropomorphic Mannequin (SAM) face. Parametric studies show that...
In this paper, a compact printed antennas with a band-stop characteristic for ultra-wideband application are proposed. The dual-oval shape is introduced to reduce the size of the dimension, thus make it more compact. In order to increase the impedance bandwidth of the proposed antenna, a partial ground and circular slot are used. By attaching an inverted Y-shaped open-circuited stub in the circular...
