The system and method for a low profile high gain dual polarization UHF/VHF antenna. In some cases a spiral antenna over a small cavity, with arms attached on either side is provided. The antenna structure is a short distance above a ground plane (e.g., less than 1/10 wavelength at ...
A low profile, electrically small wideband array antenna suitable for the portable radio and radar applications has been developed. The availability of low-loss high-permittivity ceramic materials ensures that the antenna element can be designed to cover lower UHF band in 300-1000 MHz, with only ...
In this paper, an ultra high frequency (UHF) low-profile antenna is proposed; it is based on the discone antenna but with addition of a back cavity, a short-circuiting structure and a two-plate top structure in order to achieve both low-profile and wideband. It is simulated and ...
