A triple-band monopole antenna with a compact size of 28mm×33mm is presented and experimentally discussed for Wireless Local-Area Networks (WLAN) and World Interoperability for Microwave Access (WiMAX) applications. The proposed antenna fed by a 50-Ω microstrip feed line comprises a T-shaped monopole radiating patch and a wide-slot ground plane. With the introduction of a wide slot etched in the ground...
Image-based rendering (IBR) is an emerging technology for rendering photo-realistic views of scenes from a collection of densely sampled images or videos. It provides a framework for developing revolutionary virtual reality and immersive viewing systems. This paper studies the design of a movable image-based rendering system based on a class of dynamic representations called plenoptic videos. It is...
A compact dual-band planar monopole antenna for 2.4/5GHz WLAN application is presented. The two resonant modes of the proposed antenna are associate with four slots which contribute to the upper resonant frequency and can reduce the size of the lower resonant length. The parametric study is performed to understand the characteristics of the proposed antenna. Experimental results show that the designed...
A novel dual-band microwave bandpass filter (BPF) is proposed using a dual-mode stepped impedance resonator (DSIR) and a three-mode stepped impedance resonator (TSIR). Either of the SIRs can not only separately generate one passband but also control the passband performance. Owing to the intrinsic characteristics of the SIRs, each passband has a pair of transmission zeros to improve the selectivity...
A two-PIFA antenna system for diversity/MIMO applications is designed with a narrow inter-PIFA spacing of only 3 mm (less than 0.024 wavelength). The proposed antenna system can cover the WLAN band (2.4-2.48 GHz) with an isolation of better than -20 dB and a maximum isolation of -37.1 dB at the central frequency. The mechanism is explained. The measured peak efficiency and gain, and the calculated...
