Abstract: Corporate fed Microstrip Antenna Array (MSAA) and Electromagnetically Coupled Microstrip Antenna Array (EMCP-MSAA) : A comparison Based on the analysis of different microstriplines of varying line widths, a low loss feed network is proposed. Gain improvement of 25% (1.5 dB) is achieved using the proposed feed network in 2×2 EMCP-MSAA. 8×8 MSAA - designed and fabricated at Ka-band. Measured Bandwidth: 4.3% and Gain: 24dB. Bandwidth enhancement done by designing and fabricating EMCP-MSAA. Bandwidth:17% for 8×8 array.
Index Terms: Antenna array, Bandwidth, Electromagnetically Coupled (EMCP), High Gain, Microstrip.
