A short broadband monopole antenna
AEU - International Journal of Electronics and Communications, 2018A novel design procedure is proposed to overcome the narrow bandwidth characteristic of the monopole antenna. Having sections with different lengths and radii as well as adding loads at two points along the antenna makes it permissible to optimize the radiation efficiency and bandwidth of the monopole antenna.

Broadband hybrid water antennas
2015 IEEE 4th Asia-Pacific Conference on Antennas and Propagation (APCAP), 2015A broadband hybrid water antenna at very high frequency band is presented. The proposed antenna is composed of a seawater monopole and a distilled-water ring antenna. The broadband of this hybrid antenna is caused by the multiple resonances introduced by the hybrid monopole-ring structure. This antenna achieves a wide bandwidth from 52.5MHz to 162.5MHz,

Microstrip antennas are inherently narrowband. The typical bandwidth of a microstrip antenna is around 4% to 7%. A considerable number of experimental approaches have been undertaken to develop microstrip antennas that have a broader impedance bandwidth than a single microstrip element achieves without external matching.

Broadband additive spiral antenna
2017 Antenna Measurement Techniques Association Symposium (AMTA), 2017A novel low cost and high performance miniaturized broadband Additive Spiral Antenna (ASA) technology (patent pending) has been developed. Unlike other conventional spiral designs, this new spiral antenna leverages Additive Manufacturing (AM) 3D zig-zag shapes to achieve an efficient slow wave radiation structure for extending spiral's low frequency ...

Self-Complimentary and Broadband Antennas
2015Frequency independent and broadband antennas are reviewed form the view points of the selfcomplementarity and self-similarity. The theory of self-complementary antenna, original and modified self-complementary antennas, and so-called log-periodic antennas are discussed.
