Design of Miniaturized Broadband Patch Antenna
Proceedings of the 2nd International Conference on Computing and Wireless Communication Systems, 2017In this study, we present a novel type of compact and broadband patch antenna configuration. The size reduction is obtaining without changing frequency thanks to etched six slots in antenna ground plane. Indeed, the electromagnetic volume of the antenna remains unchanged even the area of the ground plane is decreasing.

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 ...

1982 Antennas and Propagation Society International Symposium, 2005
Investigations are reported of an electrically short, asymmetrically fed broadband antenna employing a base isolation choke, The base isolation choke minimizes excitation of the mounting platform and improves radiation patterns. The asymmetrical feed optimizes the antenna current distribution over the 30 to 90 MHz frequency range resulting in improved ...

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.

Broadband UHF flexible vivaldi antenna
2013 Loughborough Antennas & Propagation Conference (LAPC), 2013A novel Vivaldi flexible antenna with a -6 dB bandwidth from 150 MHz up to 900 MHz is presented. The whole antenna is realized on a 600 × 600 mm2 silicone foam substrate. In this paper we describe the design, the realization and the performances of this high gain and directive antenna.

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.

Abstract : The subject material may be classified in three separate topics. These are: the analysis of dielectric slab-covered waveguide arrays on large cylinders (extended array coverage), scattering from dielectric-covered periodic screens of small rectangular apertures (broadband antenna/radome technology), and the analysis of a stripline fed notch ...

Compact broadband stacked microstrip antennas
Microwave and Optical Technology Letters, 2005Various stacked broadband microstrip antennas using compact variations of the rectangular microstrip antenna, such as C-shaped, H-shaped, square-ring and S-shaped antennas, are proposed. The effects of using combinations of these compact antennas as a fed or stacked element on the bandwidth, gain, and radiation pattern of the antenna are discussed ...

IRE Transactions on Antennas and Propagation, 1959
A multislot antenna was built, of which the VSWR is smaller than two in the band of 100 to 1000 mc. The principle of this antenna is analogous to the one of pass band filters in which few modes of resonance are possible, appearing one after the other when frequency varies in the band.

A broadband omnidirectional antenna
Proceedings of IEEE Antennas and Propagation Society International Symposium and URSI National Radio Science Meeting, 2002Anechoic chamber characterizations and signal verifications required a broadband omnidirectional antenna. A tapered slot antenna combined with a biconical antenna was modeled and a prototype was built. Measurement results are discussed and are consistent with the requirements. >
