Wide bandwidth and low profile antenna is required to recent generation communication devices and multi-functional radar. Tapered slot antenna (TSA) or Vivaldi antenna is the conventional antenna for ultrawideband array ULTRA WIDE BAND RADAR BASED BREAST CANCER DETECTION USING ...

design, and develop an aperture coupled patch array with wide operating bandwidth (30%), high gain (17.5dBi), low SLL (20dB), and high Forward to Backward (F/B) ratio (21.8dB). The frequency range targeted here is the 2.4 to 3GHz frequency band because of its wide application in WLAN, LTE (Long Term Evolution) and other communication systems.

Details of antenna design are described andexperimental results are discussed.Keywords: microstrip antenna, array antenna, minimized ground planeThe microstrip patch antenna can meet these requirements.Further, dual or triple band frequency operations have gained wide attention in... Meander-slot and U-slot antenna arrays for wide-band ... Narrow-band resonant rectangular slot antennas used in earlier designs are replaced by meander- slot antennas and their modifications, in order to increase the frequency bandwidth and efficiency of the system. Numerical results for finite arrays of... A Cavity-backed Coplanar Waveguide Slot Antenna Array… In this thesis, a cavity-backed slot antenna array is designed for relatively wide instantaneousSlot antennas are known for their sturdy, planar structure and have long been a prominent part of wireless systems.The design is built for operation in the C-band (around 5GHz) but can be scaled to other... slot array | Bandwidth (Signal Processing) | Antenna… Slotted-waveguide antenna arrays are attractive for many millimetre-wave radar and communication applications because of their low loss, high efﬁciency and ﬂatness. These antennas may be either standing-wave or travelling-wave arrays of various radiating slots. Standing-wave arrays have a...
