A cylindrical dielectric resonator antenna (CDRA) fed by nonresonant microstrip patch excites HEM<sub>12&#x03B4;</sub> mode for efficient radiation. A 2 &#x00D7; 2 antenna array with such an antenna element is designed at the center frequency of 9.04 GHz for obtaining higher directive gain. A prototype has been fabricated with FR-4 substrate, and(More)
This work focuses on design and analysis of microstrip patch antenna as well as effect of slots made on patch antenna to improve the bandwidth. A microstrip line fed, dual slot, triple band, rectangular microstrip patch antenna is designed. The designed antenna is most suited for C band, X band and KU band applications. The return loss is below −10 dB in(More)
A miniaturized four-element microstrip array of dimension (22 9 19 9 1.58) mm has been designed for ultra wideband (UWB) application. Unlike existing UWB arrays, the new UWB array is proposed for multiband applications. The key contribution of this paper is that both the layers (upper and lower) of FR4 substrate have been used to design the radiating(More)
In this paper, a Co-planar waveguide (CPW) fed wide bandwidth slot antenna is proposed for UWB applications. The antenna consists of a rectangular slot modified at both side of the CPW feed forming two symmetrical step like ground structure. The proposed antenna structure is simulated by using Finite element Method based ANSOFT HFSS electromagnetic(More)
