Abstract
The electrically small phased antenna array is investigated. High permittivity dielectric and magnetodielectric materials (MDM) are used for antenna array substrates to miniaturize antenna size. To analyze material parameter influence on antenna performance, the same refractive index is considered for dielectric and MDM. The basic parameters of high permittivity-based, and MDM-based microstrip patch antenna arrays are compared. The simulation results show that the usage of MDM results in the improvement in bandwidth and isolation between elements, perfect impedance matching (voltage standing wave ratio (VSWR) < \(~1.1\) for center frequency) between material and free space over a much wider bandwidth.
