A Study of Partially Shorted QMSA Characteristics
부분 단락 QMSA의 특성 연구
Abstract
We designed and fabricated partially shorted QMSAs(Quarter-Wavelength Microstrip Antennas) for 850[MHz]band on various Copper-clad Laminates substrates (TACONIC company), where the width of the radiation patch is identical with that of the ground plane and the radiation patch is partially shorted to the ground plane. The resonant frequencies and the return losses according to the electrical thickness were measured by reducing the PSW (Partially Shorted Width) to 0[mm]. As a result, a good characterized antenna with an average 11% reduced resonant length and a return loss -15.86~-30.68[㏈] was obtained when the total PSW was in the range of 70% of radiated patch width, compared to the conventional QMSA.
