A design method for a compact square loop antenna fed by a microstrip (MS) line for indoor digital television (DTV) applications is proposed. The proposed antenna consists of a square loop, circular sectors, and an MS line. The square loop combined with circular sectors is printed on one side of a substrate, and a 75 ohm MS line is printed on the other side. The circular sectors are used as a w...

An internal compact printed loop antenna with matching element is presented for laptop applications. Bending to the printed loop structure is employed to reduce the size of antenna. A matching element is used at backside of the substrate to enhance the bandwidth of the antenna. The matching element is of rectangular shape with inverted U shape slot in it. The proposed antenna with wideband char...

In this paper, we evaluated the characteristics of the magnetic core loop antenna that is used to receive long wave radio signals for time standards. To evaluate the receiving sensitivity of the antenna, we calculated the antenna factor of the magnetic core loop antenna by combining a magnetic field simulation and a circuit simulation. The simulation results are in good agreement with the resul...

A folded loop antenna for handsets has already been introduced and shown as one of balanced feed antennas for handsets, which is very effective to mitigate the antenna performance degradation due to the body effect. In addition, to be lower profile of folded loop antenna, Built-in folded dipole antenna, which has a structure folded loop elements sideway so that the antenna can be placed on the ...

I’ve heard it said that successful medium wave DXing is 50% antenna and 50% receiver. In order to get the most out of the antenna factor, those with sufficient real estate will erect a EWE, Beverage, KAZ or other outdoor antenna. For those like me with little space or who have restrictive homeowners associations, one of the antennas of choice will likely be an indoor loop antenna. This might be...

The chapter addresses the problem by presenting an analytical model for a 3-dimensional single folded loop antenna with detection coverage in space. Based on the antenna theory, the inductance and impedance of the loop antenna is investigated. Design issues including antenna topology, read range, tag orientations, proximity of metal and other antennas are addressed to determine proper antenna f...

This paper presents the design of a multiband square patch antenna with Sierpinski gasket slot in top surface of substrate and Koch loop shape slot in ground. This antenna has been designed to operate within 0.1GHz to 3 GHz frequency range. The antenna has been simulated using IE3D simulator software. The experimental result of the proposed antenna exhibits the five bands. Keywords-Square Patch...
