摘要: Microstrip patches and dielectric resonators (DRs) are two low-profile variants of modern microwave wireless antennas. However, the DR antenna (DRA) is relatively new still passing through stages development. Both quite similar in terms performance characteristics. This article focuses on a meaningful comparative study where we have considered all commonly used feed mechanisms such as coaxial probe, microstrip line, rectangular aperture for both antennas operating near same frequency. Circular geometry, i.e., cylindrical DRA (CDRA) circular patch (CMPA), been chosen, systematic investigation based thorough experiments has executed. Multiple sets prototypes fabricated measured at 4 GHz. All available data furnished compared, indicating relative advantages disadvantages. should provide qualitative quantitative instructions to designer choosing right element corresponding design requirement feasibility.
