dielectric constant of 9.4 and loss tangent of 4.0e-4. The proposed antennas may find applications in Wireless Local Area Network (WLAN). Keywords: - bandwidth, dielectric constant, microstrip antenna, slot patch, substrate I. INTRODUCTION Communication can be broadly defined as the transfer of information from one point to another [1].
feed the antenna using aperture slot coupling. aperture slot coupling has the advantage of providing increased bandwidth compared to any other feeding mechanisms. OR if you have 2 substrates in your antenna design, insert a foam material between the two substrates which act as a spacer with dielectric constant almost equal to 1.( it would be a ... A Bandwidth Improved Circular Polarized Slot Antenna Using ... A circular polarized (CP) slot antenna is designed with a slot composed of multiple circular sectors (MCS). The design has advantages of having a wide 3 dB axial ratio (AR) bandwidth of 57.4%, achieving a good AR smaller than 2 dB in most areas of the frequency range. The design of the antenna follows a multi-objective optimization procedure that applies computational power rather than human ... T-slot PIFA with Enhanced Bandwidth for Mobile Handset
