Abstract

In this letter, a planar invertedโ€F antenna with a slot on a ground is proposed to improve the antenna radiation efficiency at the CDMA band of 824โ€“894 MHz. In this configuration, the electric fields are more confined to the invertedโ€F section and the endโ€point of the ground. The measured results show that the radiation efficiencies of the proposed antenna are improved by up to 16.8% and that the radiation patterns are similar to those of the antenna without a slot. ยฉ 2011 Wiley Periodicals, Inc.

## Abstract The performance of a slotโ€loop antenna with a very narrow outer conductor can be significantly improved by connecting to an extended ground plane whose length is a quarter wavelength. The antenna has a reduced size and wider impedance bandwidth. Simulations have been carried out in the
