Description
Summary:Due to their large bandwidth, ability to integrate easily with microwave and millimetre-wave circuits, planar low-profile configuration, inherent beam-scanning abilities with frequency and narrow beam [7-13], microstrip LWAs continue to be a popular choice. Several LWAs have been built for the purpose of fixed-frequency scanning, which includes a multiterminal MLWA [14], Fabry-Perot LWA [15-17], composite left/right-handed (CRLH) LWA [18], and half-width MLWAs [19]. Since there is a strong attachment of electric field between the ground plane and microstrip, the fundamental mode of a microstrip line never radiates. [...]to the effective capacitance without patches, the longer patches bring out a reduced effective capacitance between the radiating edge and ground. [...]triangle patches cause the direction of the main beam to be moved towards the endfire. [16] Necibi O, Gharsallah A.
