A printed monopole antenna for quad-band operation in the mobile phone has been proposed and studied. The antenna occupies a volume of 24.3 x 20 x 4 mm3 with a very low height as compared to others, yet it can cover two wide bands centred at about 925 MHz and 1920 MHz to realize GSM/DCS/PCS/UMTS operation. Good radiation characteristics of the antenna over the operating bands have also been observed...
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...
A broadband dual-polarized magneto-electric dipole with loaded dielectric substrate suitable for GSM 1800 and GSM 1900 systems have been designed and tested. Dual polarized antenna is popular in wireless communications as it employs diversity technique to combat multi-path fading for enhancing channel capacity. Two pairs of short-circuited patches are fed by four Gamma shaped probes (with the ground...
