On board systems are of growing interest for aerospace applications due to the increase of air traffic as well for civil as for military applications. Moreover, the spread out of drones leads to new security issues. On board systems requires not only detection capabilities but also a "sense and avoid" operation mode. This article describes the...

This paper presents a wideband multiband antenna realized on a small ground plane dedicated to cover LTE 700 (790 - 862 MHz), GSM (880 - 960 MHz), DCS (1710 - 1880 MHz), PCS (1850 - 1990 MHz), UMTS 2100 (1920 - 2170 MHz) and UMTS 2600 (2500 - 2690 MHz) standards. The proposed antenna is a QSC-IFLA (Quasi-Self-Complementary Inverted-FL Antenna)...

This paper presents the study of the different feed positions for a multiband and broadband antenna used for mobile phone applications, in order to cover the DCS (1710 -1880 MHz), PCS (1850 - 1990 MHz), UMTS2100 (1920 - 2170 MHz) and WLAN (2500 – 2690 MHz). The proposed antenna is an "Inverted-F Antenna" (IFA) with quasi self-complementary...

This paper presents a decoupling technique for two close radiating elements, designed for the low LTE band [0.7-0.9] GHz. This method can be applied to a coupled antenna structure with an axis of symmetry. It consists in using a power splitter and a phase shifter between the two ports of the symmetrical antenna structure, in order to feed them...

This article presents a new miniature antenna for UHF RFID reader. Circular polarization and size reduction (70% than a classical patch) of the radiating element are achieved by using a single probe feed and two short circuits. The measured axial ratio bandwidth obtained with the proposed antenna is about 270 MHz (28.2%). This antenna has a...

This article presents a new miniature antenna for UHF RFID reader. Circular polarization (CP) and size reduction of the radiating element are achieved by using a single probe feed and two short circuits. The simulated axial ratio bandwidth obtained with the proposed antenna is about 140 MHz (15.5 %). This antenna has a total volume of 270 mm x...

This paper presents a technique for decoupling close radiating elements printed on FR-4 substrate designed for the [0.7-0.9] GHz LTE low frequency band. This is obtained by using a power splitter and a phase shifter connected between the feeds of two symmetrical antennassurrounding a third one. This method provides a high isolation of 70 dB at...
