Wideband patch dipole antenna

2005 IEEE Antennas and Propagation Society International Symposium, 2005
A novel wideband patch dipole antenna is proposed and simulated by Ansoft HFSS. Calculated results show that the relative bandwidth can reach 66.7% with VSWR less than 2. A model antenna is fabricated with microstrip structure. Good agreement is achieved between experimental and simulated results.

Planar wideband antennas [PDF]

open access: possible, 2016
Wideband antennas with omnidirectional coverage have both military and commercial applications. In one embodiment, the Planar Inverted Cone Antenna (PICA) is composed of a single flat element vertically mounted above a ground plane. A geometry of Planar Inverted Cone Antenna (PICA) is based on the conventional circular-disc antenna with trimmed top ...

Ultra-wideband antenna arrays

IEEE Antennas and Propagation Society International Symposium. 2001 Digest. Held in conjunction with: USNC/URSI National Radio Science Meeting (Cat. No.01CH37229), 2002
The radiation characteristics of ultra-wideband (UWB) monopulse arrays are discussed in this paper. The UWB arrays considered here consist of ultra-wideband sources radiating coded sequences of ultra-narrow Gaussian mono-pulses with very low duty cycle.

Wideband saline-water antenna

Wideband and Multi-Band Antennas and Arrays, 2005
Basic monopole antennas are becoming less suitable for wireless communications because most applications demand multi-band operation. Dielectric resonator antennas (DRAs) can be made with a wide range of materials and allow many excitation methods. We are investigating liquid dielectrics as DRAs at frequencies between 1-4 GHz. In this paper we report a
