| Popis: | A new microstrip patch antenna for ultra-wideband applications is presented in this paper. The design and performance of the antenna component are discussed. The propounded antenna is mounted on a compact FR-4 substrate having dimensions 20 x 30 x 1.6 mm3 with relative permittivity εr=4.3. The rectangular patch antenna is slotted with two types; rectangular and semi-circle slots so as to ensure a broad bandwidth. The results reveal that the antenna covers the frequency range of 3.1–7.5 GHz with a reflection coefficient reduced to -55 dB and a maximum gain of 5.9 dB. The details of the simulated and measured results for reflection coefficient are presented, showing a good agreement between them. To analyze the effect of the slots, the surface current distribution is investigated. The performances of good impedance matching are achieved within the operating band. Simulations are performed using CST Microwave Studio. The propounded antenna can be deployed for UWB applications and other radio communication services systems such as high-resolution radar, military communication, communications and sensors, position location and tracking |
