A compact substrate‐integrated‐waveguide (SIW) monopulse slot antenna array with TE20 mode is proposed, manufactured, and tested in this communication. The TE20 mode electric field distribution is used in this antenna design. The phase difference required by the monopulse system is constructed by changing the orientation of the end of the top micro...

... 5-7 But, these antennas suffer from poor performances due to bidirectional radiation characteristics. Substrate integrated waveguide (SIW) based antennas [8][9][10][11][12][13][14][15][16][17][18][19] are a better substitute to provide good radiation characteristics in a planar structure. In References 8-12 linearly polarized radiation in single band, dual band and triple-band of frequencies is obtained. ...
A novel design of dual‐frequency dual‐sense circularly polarized (CP) substrate integrated waveguide (SIW) cavity‐backed slot antenna is presented for dual‐band wireless communication systems. The proposed antenna consists of square SIW cavity, asymmetrical bow‐tie‐shaped cross slot and probe feed. Due to use of asymmetrical bow‐tie‐shaped cross slot, circularly polarized wave radiates at two different frequencies with opposite sense of polarizations. The RHCP radiation occurs at (10.45‐10.54) GHz (Lower band) and LHCP occurs at (11.26‐11.34) GHz (Upper band). Moreover, in each band, sense of polarization can be change by changing the feed position. The front to back radiation ratio (FTBRR) is more than 10.5 dB and cross polarization level is lower than −20 dB in both the bands.
