For a linearly polarized antenna, performance is often described in terms of its principal E and H plane patterns.A slot antenna's main advantages are its size, design simplicity, robustness, and convenient adaptation to mass production using PC board technology. Radial line slot antenna The Radial Line Slot Antenna (RLSA) is a planar antenna having attributes such as high eciency of about 70% and higher gain of about 33 dBi [1]5. Davis, P. W. and M. E.

A linearly polarized radial-line slot-array antenna ... - CORE The beam shaping of a linearly polarized radial-line slot-array (LP RLSA) antenna is demonstrated with the production of a prototype with a broadened main beam pointed in an arbitrary direction. The method of synthesis is presented, which utilizes a simple but accurate radiation model for the RLSA antenna to predict radiation characteristics.
A typical vertical whip antenna (a monopole) possesses an omnidirectional vertically polarized pattern, and such an antenna can be comparatively small at high frequencies, such as UHF.
