Abstract

A small 1.1‐cm^3^ one‐turn loop patch antenna located 2.5 mm above an 18 × 25 mm ground plane separated by a dielectric substrate with relative permittivity of 9.8 is presented. By varying the length of a thin quarter‐wavelength matching line, it is possible to change the resonant frequency. An RLC circuit model is used to determine the minimum quality factor Q. It is shown that the proposed loop yields a bandwidth performance close to the theoretical limit. The antenna has a 14.5% bandwidth at the resonant frequency of 2.04 GHz. © 2005 Wiley Periodicals, Inc.

## Abstract In this article, an electrically small loop antenna using capacitive loading is proposed. The loop antenna acts as an inductive element and the gap between two lines of SRR in the ground plane acts as a capacitive element; hence the combined system with these two elements is operated as

## Abstract The design and radiation characteristics of a wideband quarter‐wave patch with a single‐layer capacitive feed are presented. The E‐plane radiation pattern of the antenna is shown to be very dependent on the size of the ground plane, and the results for two extreme cases are obtained in
