AbstractAn unbalanced loop antenna of simple construction is proposed for broadband linearly polarized applications. By introducing a gap in a half loop mounted vertically over a ground plane, the bandwidth of the antenna can be substantially increased relative to its classical balanced version.

2008 IEEE Antennas and Propagation Society International Symposium, 2008
A broadband planar antenna with stable radiation patterns is presented. It consists of a suspended radiator fed by a vertical feed through an n-shaped microstrip. The measured impedance bandwidth is 3.1-5.1 GHz for a return loss of |S11| < -10 dB, and an average gain of 7.7 dBi is achieved. There is no beam squinting across the operating frequency band.

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

The study on microstrip antenna with miniaturization and broadband
2011 4th International Conference on Biomedical Engineering and Informatics (BMEI), 2011As the entrance, the antenna has the most direct impacts on their performances of wireless communication system. Microstrip antenna has considerable potential value in communication application by virtue of compact-structure, low-profile, light-weight, small-volume, easy to be fabricated and integrated with microwave integrated circuits.

Broadband Optical Antenna with a Disk Structure
Passive Components and Fiber-Based Devices, 2011Broadband optical antennas are of interest as they can transmit more information like traditional microwave UWB antennas. This paper presents a design of broadband optical antennas with a concentric disk structure. An equivalent circuit for the optical antenna with a disk structure is introduced.

Broadband antenna quality control
Upravlenie kachestvom (Quality management), 2023This article discusses the main issues of quality control of broadband antennas. An algorithm for determining the gain, the importance of using the Helmholtz equation for determining the parameters of the electromagnetic field in the near zone of the antenna complex is considered.

Overview of Research on Broadband of Dipole Antenna
2019 IEEE 19th International Conference on Communication Technology (ICCT), 2019The methods of realizing broadband of dipole antenna are summarized and analyzed. Due to the narrow operating frequency band of the dipole antenna, in order to improve the bandwidth of the dipole antenna and improve its spectrum efficiency, the broadband of the dipole antenna is studied. This is also in line with the research trend of broadband antenna.

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.

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. >
