An innovative LDS 4G antenna solution operating in the 698–960 MHz band is presented. It is composed of two radiating elements recombined in a single feed broadband antenna system using a diplexer. This circuit is realized thanks to lumped components, assembled directly on the plastic piece which supports the antenna. Corresponding measurements show a 260 MHz wide bandwidth (for S11@-6dB) and close...
An antenna-system covering the LTE700 and GSM850/900 standards is presented. The proposed structure has been designed to fit in generic handheld devices. It has been manufactured using Laser Direct Structuring technology on a plastic piece. The principal design challenge for the antenna is to cover the target band with a short ground plane (75mm). To be able to cover from low LTE (700–787MHz) up to...
An innovative LDS 4G antenna solution operating in the 698–960 MHz band is presented. It is composed of two radiating elements recombined in a broadband single feed antenna system using a multiband matching circuit design. Matching interfaces are synthesized thanks to lumped components placed on the FR4 PCB supporting the LDS antenna. Measurement shows a reflection coefficient better than −6 dB over...
In order to counteract the antenna impedance mismatch due to its interaction with the environment, one solution is to add an antenna tuner between the front-end module and the antenna. In this paper, we present the large signal measurement of a 4G integrated antenna tuner, previously presented in [1]. The tuner has been realized in STMicroelectronics 130 nm CMOS SOI technology and operates between...

The mobile phone antennas exhibit a very low real impedance value especially in lower LTE (698–787MHz) and GSM (824–960MHz) bands, since the antennas are electrically small compared to operating wavelengths at these bands. Obtaining sufficiently low reflection coefficient and high TRP in a considerable bandwidth from such an antenna is very challenging without exciting proper currents on the PCB of...
In this paper, an innovative 4G antenna solution operating in the 698–960 MHz band, is presented. It is composed of two radiating elements recombined in a single feed antenna-system using an integrated power divider/combiner, synthesized thanks to five lumped components. Simulations using realistic SMD (Surface Mount Devices) components allow reaching a matching better than −6 dB, confirmed by measurement...
In order to counteract antenna impedance mismatch due to interaction with environment, one solution is to use a tuner between the front end module and the antenna. In this paper, a 4G antenna tuner integrated in STMicroelectronics 130 nm CMOS SOI technology and operating between 2500 MHz and 2690 MHz is described. Thanks to high power CMOS SOI Digitally Tunable Capacitances (DTCs), the proposed tuner...
