Compact rectangular slot antenna with a novel coplanar waveguide fed diamond patch for ultra wideband applications

Abstract

This letter presents a rectangular slot antenna with a novel coplanar waveguide fed diamond patch covering frequency range from 2.27 to 10.63 GHz based on S11 < −10 dB, 129%. The fabricated antenna has a small size as high as 42 × 42 mm2. The measured results are in good agreement with simulation results. The measured radiation patterns are nearly omni‐directional over the most of the frequency bandwidth. The antenna gain ranges from 1.6 to 7.6 dBi. The simple structure, compact size, and good characteristics make the antenna easy to use in commercial ultra wideband systems. © 2009 Wiley Periodicals, Inc.

Compact Uwb Antennas With Inverted E- And F-Shaped Slots for Bandnotch Characteristics

“…Moreover, with using DGS for this antenna, the bandwidth is improved which is about 3.1 to 11.47 GHz. The proposed inverted E-shaped notch antenna is compact in size compared to the design recently reported in [19][20][21][22][23][24][25][26]. The DGS ground structure has improved results for three proposed antennas.…”

CPW-fed slot antenna for UWB short-range impulse radar systems

“…Many reports about omni-directional planar UWB antennas have been published recently, for example, tapered-slot fed slot antenna [8], rectangular slot antenna with a CPW fed diamond patch [9], microstrip-line fed circular corner monopole antenna [10], printed circular disc monopole antenna [11], and so on.…”

A Racket-Shaped Slot Uwb Antenna Coupled With Parasitic Strips for Band-Notched Application

“…As an essential part of the UWB system, UWB antenna has been developed widely and rapidly. Although UWB antennas using other planar structures such as dipole patch antennas [1][2][3][4] and slot structures [5][6][7] can be achieved well, monopole antennas are more favorable for UWB application due to their symmetrical and omnidirectional radiation patterns, wide impedance bandwidths, low cross-polarization levels, easy fabrication processes, and so on in [8][9][10][11][12][13].…”
