Narrow frequency bandwidth antenna is a typical shortcoming for most of the communication devices. Thus, a single radiating element which able to have resonant frequencies covering from 780MHz till 3000MHz with at least VSWR of 2.5:1 is critically needed especially for a mission critical two-way portable radio. A novel patch antenna was designed to cater for this inadequacy. Using one radiating element...
A novel wearable antenna for wireless communications is presented in this paper. This paper has discussed the possibility of employing a belt buckle as an antenna, bringing benefits such as removability and the ability to hand portable wireless devices from the belt itself. The antenna consists of a belt buckle, hinge, denim waist band and electrical connections. The antenna was fed by a microstrip...
The compact antennas with balanced effect have been introduced with the change of their configuration. These antennas are effective to mitigate the antenna performance degradation due to the human body effect and also have flexible adjustment of antenna impedance and capacity of wideband and multi-resonance characteristics. Second, a downsizing technique of antenna for handset by utilizing a magnetic...
