Abstract

The design of a miniaturized low‐profile monopole patch antenna is investigated.The printed configuration consists of a shorted center‐fed circular patch and a shorted concentric parasitic annular ring. Compared with the center‐fed circular patch antennas, this ensemble is a lower profile of 0.08λ~0~ (at 2.442 GHz) and a smaller annular ring radius of 0.13λ~0~ with 13.7% impedance bandwidth VSWR ≤ 2. Also, it has an average gain 3.5 dBi and omnidirectional radiation and is suitable for indoor wireless local area networks. The measured results are in good agreement with the simulated ones. © 2010 Wiley Periodicals, Inc.

## Abstract A dual and wideband single‐element rectangular dielectric resonator antenna (DRA) excited by a microstrip aperture is investigated experimentally. It provides two passbands in the ranges of 2.21–2.855 GHz and 4.385–5.455 GHz, which are popular bands for wireless local‐area networks (WLA

## Abstract This paper presents a novel design for a low‐profile planar monopole antenna. The proposed antenna is a rectangular planar monopole with folded end. Its total height is about 0.12 λ~0~ (the free‐space wavelength of the lowest operating frequency of the antenna), which is lower than othe

## Abstract A broadband low‐profile printed T‐shaped monopole antenna is presented. It is demonstrated that, by short‐circuiting the central arm of a low‐profile T‐shaped monopole to the ground plane, much improved impedance matching over a wide frequency range can be achieved.

## Abstract A body‐implantable miniaturized and broadband stacked antenna suitable for biotelemetry communication is proposed. By properly arranging a rectangular three‐layer slotted patch structure, the designed antenna with only 10 × 10 × 1.9 mm^3^ can provide a −10 dB impedance bandwidth of 50 M
