Helmet-Mounted Inverted-F Antenna at VHF Band

Radiation Pattern Analysis of Inverted-F Antenna Mounted on the Side Wall of a Long Cylinder

An analytical technique is proposed for estimation of the radiation pattern of inverted-F antenna (IFA) which is mounted on the side wall of a long cylinder. The method can be applied to describe the IFA radiation in a lot of practical cases. It is indicated that this radiation pattern is a combination of radiation patterns of a horizontal and a vertical small radiator, near the cylinder with a...

Compact multiband Planar Inverted F Antenna (PIFA)

Aeronautical Channel Modeling at Vhf-band

| A class of aeronautical wideband channel models is proposed, featuring parking & taxi environments , take-oo & landing situations, and en-route scenarios for air-ground links and air-air links. Typical and worst-case parameter sets are suggested, based on published measurement results. The models are suitable for an implementation of simple channel emulators on digital computers or in hardwar...

A Compact Single/Dual-Band Printed Inverted-F Type Antenna Structure

Abstract: In the first part of the paper a compact version of a printed inverted-F type antenna is presented. The compactness is achieved by placing the necessary matching line at the side of the feeding line with the main radiator not at the other side of the feeding line, as for the ordinary IFA. Another advantage is the possibility of an additional λ/2-resonance along the matching line, whic...

Design of a Triple-Band Planar Inverted-F Antenna For Cellular /PCS/ DMB applications

Due to the rapid development and widespread usage of various communication systems, multiband internal antennas are necessary for recent mobile handsets [1]-[3]. To meet the antenna requirement for hand-held terminal, the size reduction is one of the key requirements while maintaining the good multiband and wideband performance. Furthermore, a small intenna that can be integrated into the hands...
