Abstract
A suspended line feed type planar array antenna has a substrate sandwiched between a pair of metal or metallized plastic plates and resonance type printed patch radiators provided in corresponding relation to openings formed through one of the pair of metal or metallized plastic plates, whereby the antenna can be reduced in thickness, weight and cost. Also, the transmission loss of the antenna can be reduced and its bandwidth can be widened.
