A novel broadband skeletal discone antenna with a compact configuration is proposed in this letter. The antenna consists of three components including a circular metal disc, a small upside-down cone, and a skeletal cone. The operating principle of this antenna is investigated by simulation, and the corresponding simulated results are also demonstrated in this letter. According to the simulation, the...
In this article, a novel compact microstrip-fed slot antenna with dual band-notched characteristic is proposed. The proposed antenna consists of a circular patch and a multiple ground plane. By inserting two U-shaped slots to the circular patch and adjusting the dimensions of the slots, the antenna can reach a frequency band-width from 2.9 to 15.6 GHz for voltage standing wave ratio (VSWR) <; 2...
The design simulation and measurement of a highly miniaturized compound spiral antenna is presented. The compound spiral antenna is designed by combining a typical equiangular spiral antenna with new terminals. Favorable wideband properties are shown in the simulated and measured results. The measured return loss is less than -10 dB in the frequency range from 1.6 to 10 GHz and the axial ratio is...
