A Compact Ultra-wide Band Microstrip Patch Antenna Designed for Ku/K Bands Applications

2017 | Keywords Ultra–Wideband, Patch Antenna, Proximity–Fed, Defected Ground Structure (DGS, Ku/K bands operation.,
A Compact Ultra-wide Band Microstrip Patch Antenna Designed for Ku/K Bands Applications
A proximity feed ultra-wide band (UWB) patch antennas with a compact size (millimetres size) for Ku/K band applications is presented. Defected ground structure (DGS) technique is employed to enlarge the bandwidth of the antenna. The proposed antenna introduces UWB performance in the frequency range of 16 GHz to 29 GHz with a compact size of 7 x 10 mm2, which ... Read more

A Compact Proximity-Fed Ultra-Wide Band Patch Antenna with Four Notched-Band Characteristics: Design and Implementation

2014 | Keywords Cedar Tree Antenna, UWB Patch Antenna;, Proximity Feed;, Four Notched Bands;, Equivalent Circuit,
A Compact Proximity-Fed Ultra-Wide Band Patch Antenna with Four Notched-Band Characteristics: Design and Implementation
In this paper, a new printed cedar tree-shaped UWB antenna with four frequency band-rejection characteristics is presented. The equivalent electrical circuit of the antenna is also presented. The antenna is compact volume of size 20 x 20 x 1.5 mm3. Matching between the designed antenna and the 50 Ohm microstrip feed line is manipulated through a proximity-fed technique. Narrow rectangular ... Read more

A Proximity-fed Ultrawide Band Patch Antenna with Four Frequency-Band Notches

2013 | Keywords Ultra-Wide Band, Four Frequency-Band Notches, Patch Antenna,
A Proximity-fed Ultrawide Band Patch Antenna with Four Frequency-Band Notches
A proximity feed ultra-wide band (UWB) patch antenna with four notched bands is presented. The proposed antenna introduces UWB performance in the frequency range of 1.9 GHz to 10.3 GHz with omnidirectional radiation pattern. Slots etching techniques are utilized to provide four notchedbands at frequencies of 2.3, 2.8, 3.5, and 5.5 GHz to avoid the interference with the wireless networks ... Read more
