The electromagnetic modelling and optimization of planar holographic antennas
Antennas based on holographic principles are attractive at millimetre wave frequencies because of their potentially relatively high directivity and low profile. Most published design work on planar holographic antennas has been based on approximate expressions and experimental experience. Little …

Research and Development of Low-Profile, Small Footprint Antennas for VHF-UHF Range Applications
<p>Efficient, but low-profile and small-footprint antennas for VHF-UHF range applications remains an ongoing work. VHF range spans approximately 54 - 88 MHz while UHF roughly ranges from 174 - 890 MHz. The inverse relationship between the physical length and resonant frequency of an antenna, which …
