Novel Multiband Millimeter Wave Antennas
Journal of Communications, 2023The design of multiband antennas is useful for providing multiple resonance frequencies required for multiple application scenarios. However, there is a scarcity of compact-sized antennas in the 70-110 GHz band. In this regard, this paper proposes two multiband millimeter wave antennas in the W and D bands.

IEE Proceedings - Microwaves, Antennas and Propagation, 2005
A reduced height automotive antenna covering the three mobile telephone bands used around the world is described. The antenna is much more compact than a conventional monopole and is printed on a PCB for low-cost production. Circuit components are used to tune the antenna to cover the regional band variations for mobile telephone systems, enabling one ...

[1992] Proceedings of the Tactical Communications Conference, 2003
Consideration is given to the Multimode Multiband Antenna program, a joint Army/Air Force/Navy program to build an antenna system for the 'Speakeasy' Multimode Multiband Digital Radio. The requirements are for a multiplatform, extremely wideband antenna system that is capable of supporting simultaneous operation of up to four different waveforms.

2016 International Conference on Microelectronics, Computing and Communications (MicroCom), 2016
Wearable antenna is a planner structure microstrip antenna used in Body Area Network (BAN). In this paper, one single band and two multiband wearable antennas are reported. Wearable materials like curtain cotton and polycot has been used as dielectric substrate to design the antennas. Antenna-1 is single band antenna. First order Koch snowflake fractal

17th International Conference on Applied Electromagnetics and Communications, 2003. ICECom 2003., 2004
In order to satisfy all the new services proposed by mobile communication providers, terminal antennas both on the base station and on the mobile end are more and more asked to handle multiple frequency bands. In this paper, performances of several types of multiband antennas are compared, taking into consideration available volume, bandwidths ...

Multiband planar antenna for wireless LAN
2015 IEEE 4th Global Conference on Consumer Electronics (GCCE), 2015A new multiband planar antenna for wireless LAN is proposed and examined, compared with the conventional antenna, FML2.4W. From the results, the maximum values of the absolute gain for the proposed antenna are equal to or higher than those for FML2.4W in two frequency bands, from 2.4GHz to 2.5GHz, from 5.2GHz to 5.8GHz.

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

Multiband Fractal Antenna for Wireless Applications
2018 6th International Conference on Wireless Networks and Mobile Communications (WINCOM), 2018In this present paper a Microstrip circular patch antennas with right angled isosceles triangles (RIT) on the edge is designed. The presented antennas are multi and wide band, small in structure and easy in fabrication. The circular patch has been fractured by superimposing the right angled isosceles triangles on the edge, and in the ground.
