A novel, low-profile, and broadband plate-loaded planar monopole (PLPM) antenna obtained through the application of transmission line modeling (TLM) is proposed. The antenna consists of a rectangular planar monopole (RPM) with small rectangular plates attached to its radiating edges. The addition of plates at edges increases the upper frequency range significantly. Simulation as well as experimental...
In this paper a novel design approach of the elliptical ring slots antenna is presented. Details of the antenna design approach is presented and discussed. This antenna has a stripline feed structure that eliminates the above limitations of probe-fed patch antennas. Simulation result illustrates about 7.3% fractional bandwidth at the frequency band of 58.1-62.5 GHz. Finally radiation pattern results...
The radiation pattern of an optimized Yagi-Uda antenna does not suffer from the minor radius alteration (such as 1/2: 50% reduction or 1/4: 75 % reduction) of elements even if the alteration is uniform for entire elements. The minor step-tapered design alteration in radius of radiating elements greatly affects the radiation characteristics of the Yagi-Uda antenna, which is originally designed with...
