A diversity antenna for a tri-band application is proposed and designed. The proposed diversity antenna consists of two wideband planar inverted-F antennas (PIFAs) and a suspended line between two PIFAs. The measured results show that the proposed antenna has a wide impedance bandwidth (37%) enough to serve a triple band (PCS, UMTS and WiMAX), a high radiation efficiency (> 50%), and a low correlation...
Platform-tolerant tag antennas are desired for ubiquitous RFID systems. Metal-mountable or wideband tag antennas can not guarantee platform-tolerance. This paper presents the design approaches of platform-tolerant tag antennas. A compact PIFA-type UHF tag antenna is proposed accordingly. Simulation and measurement results are provided to demonstrate the platform-tolerance feature of the proposed antenna...
A wideband antenna for use in the vehicular environment is presented, based on the uniplanar CPW fed PICA slot antenna. The antenna provides a very wide impedance bandwidth from 730 MHz to 15 GHz, sufficient for many of the wireless services used in modern automobiles. The radiating mechanism of the antenna is able to be described in two ways at various frequencies, leading to alternate radiation...
The ultra wide band (UWB) systems require antennas having a very broad impedance bandwidth. The planar inverted-F antenna (PIFA) is widely used in mobile and portable devices due to its excellent performance. But it is not used as an ultra wide band antenna as it is assumed to be a narrow band antenna. This paper is aimed at addressing this problem by introducing a PIFA antenna having a parasitic...
The author has proposed an electromagnetically coupled inverted-FL antenna with a self-complementary structure. The proposed antenna achieved a broadband characteristic without a matching load and an impedance transformer. This antenna acquired the broadband and multi-band characteristics necessary for the required mobile phone services.
A novel of comprehensive study and useful information for the design of broadband planar inverted F antenna (PIFA) is proposed. The antenna including the ground plane has a total dimension 6 mm times 70 mm times 30 mm has been optimized to be operating within WLAN application standards. The size of this antenna makes it ideally suitable for handheld wireless communicators. The physical parameters...
