Compact Printed Antenna for Mobile Phone
Advanced Materials Research, 2013Co-Authors: Tsang Yen Hsieh, Jyh-liang Wang, Chuan Chou Hwang, Wei Chuan ChenAbstract:A small-size printed antenna is proposed for the application of mobile phones. The antennacomprisesan outer strip, an inner strip, and a common section.It not only occupies a compact area of 25 × 20 mm² butalsosupports two wide bandswithinthe resonantmodes. Prototypes of the antenna had been constructed and experimentally verified. The measured results of the antenna show the bandwidth cover the existing service bands of GSM/DCS/PCS/UMTS within 6 dB return Loss Specification, and also have good radiation patterns and antenna gains.This antenna is well suitable to be used for mobile phone application.

Internal compact small-size printed compound monopole antenna for mobile phone
IEEE iWEM2011, 2011Co-Authors: Tsang Yen Hsieh, Jyh-liang Wang, Wei Chuan ChenAbstract:In this paper, we propose a small-size printed compound monopole antenna for application in mobile phones as an internal antenna. The antenna comprises an outer strip, an inner strip, and a common section. The antenna structure is simple and easy to manufacture. It occupies a compact area of 25 × 20 mm² only, yet generating two resonant modes to form two wide bands. Two operating frequency bands of the antenna covering the GSM/DCS/PCS/UMTS are met with 6 dB return Loss Specification, so it is well suitable to be used for mobile phone application.

Characterization of damper-to-damper wireless channel in small cars
2018 IEEE MTT-S International Wireless Symposium (IWS), 2018Co-Authors: Carlos A.m. Costa, Miguel Dheans, Peter Baltus, Hao GaoAbstract:The increasing use of Intra-Vehicular Wireless Sensor Networks (IVWSNs) in smart cars has enabled advances on Intelligent Transportation System (ITS) and also extended electric cars driving range by reducing cable weight. Intra-vehicular wireless systems have been characterized at 2.4 GHz and UHF bands. However, works on channel characterization of damper-to-damper wireless systems are still limited. This paper presents a damper-to-damper path Loss characterization at 2.4 GHz frequency band for small cars. Dynamic on-field measurements on damper-to-damper antennas are used to derive path Loss Specification and coherence bandwidth for an intra-vehicular wireless communication system. Static measurements show the impact of antenna polarization in damper-to-damper path Loss.

Damper-to-damper path Loss characterization for Intra-Vehicular Wireless Sensor Networks
2017 47th European Microwave Conference (EuMC), 2017Co-Authors: Carlos A.m. Costa, Miguel Dheans, Hao Gao, Thibault Le Polain, Rainier Van Dommele, Bart Smolders, Peter BaltusAbstract:Intra-Vehicular Wireless Sensor Networks (IVWSNs) is one of the major advances in electrical smart cars. It could extend the driving distance of E-cars by reducing the weight of bulky cables. It can also bring more sensing functions, turning the car into smart units for Intelligent Transportation Systems (ITS). Until now, most works of IVWSNs channel characterization are focused on in-car wireless communication. This paper presents for the first time, to author's knowledge, the channel characterization of a non-line-of-sight damper-to-damper wireless communication at 2.4 GHz frequency band, including the signal reflection from ground. A method of 3D EM simulation is provided. Static and dynamic on-field car measurement is also performed on a commercial car with different road profiles. It shows that different road profiles equally impact path Loss Specification because of similar permittivity. From on-field measurements, it proves that 5.25 MHz frequency isolation leads to uncorrelated channels.
