A broadband microstrip antenna: SGMFP antenna
Microwave and Optical Technology Letters, 2003AbstractA novel structure of broadband microstrip antennas, termed the SGMFP antenna, is proposed. It is consisted of a slot in the ground plane, a microstrip feedline supported on a substrate, a foam layer, and a patch. It can achieve broad bandwidth and high polarisation purity.

Broadband/Multiband Printed Antennas
IEICE Transactions on Communications, 2005Broadening the frequency bandwidth of antennas has been one of the major subjects concerning antenna design technologies. Two of the major subjects for microstrip antennas, which appeared in the 1970s, have also been the broadening of the frequency bandwidth and the sharing of multifrequency bands. In this paper, we describe the broadband and multiband

In this chapter we will study some simple dipole type configurations that can provide a broader bandwidth: the cylindrical dipole and biconical antenna. In addition, the chapter introduces the folded dipole antenna, which can provide better matching characteristics than that of the single dipole.

This thesis investigates a novel dual frequency range low profile antenna system containing two nested spiral antennas operating over 2 – 18 GHz and 30 – 40 GHz respectively. The exploration and development of a broadband microstrip spiral without cavity backing has been implemented in the range of 2 - 18 GHz.

The directional patterns (DP) of antennas for the monopulse (MP) coordinate measurement method have complex, sometimes contradictory, requirements. For a survey station, for a number of reasons, some kind of compromise must be provided between the absolute signal level and the width of the linear area of the direction finding characteristic (DFC ...
