This paper proposes and studies a monopole antenna with a parasitic plate for WLAN applications. In this design, a microstripline-fed rectangular patch creates a resonant mode at 3 GHz. Furthermore, a parasitic plate is added on the side of the ground plane to generate a dual-band operation of 2.39 to 2.91 GHz and 4.06 to 6.73 GHz. The overall size of the proposed antenna is only 26x40x0.8 mm³(W_subxL_subxH). The monopole antenna with a parasitic plate is calibrated for WLAN applications, which cover the bands from 2.4 to 2.48 and 5.15 to 5.825 GHz. This antenna has the advantage of compact size, simple structure and good radiation characteristics.

The author discusses the function of a femtocell in 4G architecture and the role of the RF power amplifier.

This is the first of a two-part series that discusses certain fundamentals in voltage-controlled oscillator design.

This paper discusses the advantages of a dedicated system-level tool over spreadsheets.

A selection from Agilent’s “Ten Things You Should Know About MIMO” are presented in this paper, with the intention of giving the user an overview of the operation of MIMO technology and test methodology. Each item uses an example to highlight the impact on the radio system or associated test. A poster that summarizes all ten points is available from Agilent on request (order information can be found at the end of this paper).

In this paper, wafer scale packaging information is shown including factors that make it low cost. RF I/O design and tested performance for the wafer scale package are shown. After the discussion of the wafer scale package design, the design and performance of a broadband driver amplifier is described.

Re-segmentation effectively enables more flexibility in the LTE eNB scheduling of resources. Instead of rigidly maintaining constant resource constraints for re-sending data, the eNB can quickly and efficiently change resource grants to suit the radio conditions, thereby balancing the resource needs of all users of that eNB.
