✦ Synopsis

In this article, we propose a modified miniature 3D inductor to implement a fully-integrated feedback wide band amplifier. A description of the LNA configuration was explained emphasizing the influence of the design parameters in the circuit performance. The circuit was implemented in a standard low cost 0.35 lm process and provides a gain that ranges from 14 dB to 7 dB in the band between 3.1 GHz and 10.6 GHz. The noise figure ranges from 2.9 dB to 4 dB in the same band. The circuit only requires 4 mA from a 3.3-V supply. Thanks to the use of the modified miniature 3D inductor a 40% of area reduction is achieved with minor performance degradation over the same circuit implemented with conventional inductors.

## Abstract A wide‐band L‐strip proximity fed rectangular microstrip antenna is proposed and investigated both theoretically and experimentally. The radiating patch is located about 0.1λ~0~ (16.5 mm) above the ground plane. The broadband characteristic of antenna is achieved by employing a thick su

## Abstract In this paper, we study a circular microstripline‐fed single‐layer single‐slot antenna. In this case, a modified circular microstrip feedline leads to good impedance matching in a wide dual band. The 10‐dB return loss impedance bandwidth is 50.8% for cellular (0.824–0.96 GHz) and GSM (0
