Abstract
A comparison between corporate fed microstrip antenna array (MSAA) and an electromagnetically coupled microstrip antenna array (EMCP-MSAA) at Ka-band is presented. A low loss feed network is proposed based on the analysis of different line widths used in the feed network. Gain improvement of 25% (1.5 dB) is achieved using the proposed feed network in 2×2 EMCP-MSAA. A 8×8 MSAA has been designed and fabricated at Ka-band. The measured bandwidth is 4.3% with gain of 24dB. Bandwidth enhancement is done by designing and fabricating EMCP-MSAA to give bandwidth of 17% for 8×8 array.
