2015-12-4 · Step and Linear-Tapered Slot Antennas The authors also studied a CP\V fed tapered ring slot antenna which consists of a 500 coplanar wavcgnidc feeding line, ... The two designs are the Step Slot Antenna and Linear Tapered Slot Ant.enna. 5.1 Step Slot Antenna: Design Dual-Band Microstrip Patch Antenna for Wireless … 2012-5-29 · in two ways: L-probe proximity fed annular ring patch and E-shaped patch. The antenna design proposed in [4]-[5] are on thick substrates which will make it difficult to integrate on miniaturized sensors. We propose a different approach where a much thinner (0.04 λ) slotted microstrip patch antenna has been designed for wideband operation. MEMS-based CPW-fed slot antenna for broadband circularly polarized (CP) radiation, especially only using a single feed. Though some circularly polarized slot antenna designs have been reported, most of these reported antennas are fed by a microstripline [9–11]. The design fed by a CPW [12, 13] is relatively scant. Meanwhile, most of the reported CPW-fed slot … Design and Performance Analysis of Dual band Circularly

DUAL-BAND BEAM SCANNING REFLECTARRAYS AND NOVEL … Dual-band Beam Scanning Reflectarrays and Novel Wideband and Polarization Diversified Planar Antennas. (August 2008) Shih-Hsun Hsu, B.S., National Cheng Kung University; M.S., University of Wisconsin-Madison Chair of Advisory Committee: Dr. Kai Chang The reflectarray antenna has been considered as a suitable candidate to replace the Design of Stacked Microstrip Dual-band Circular Polarized
The design of a microstrip‐fed annular‐ring slot antenna (ARSA) with circular polarization (CP) radiation is initially studied. To obtain CP radiation with broad 3‐dB axial ratio (AR) bandwidth that can cover the WiMAX 2.3 GHz (2305–2320 MHz, 2345–2360 MHz) and WLAN 2.4 GHz (2400–2480 MHz) bands, a novel technique of extending an inverted L‐shaped slot from the bottom section of ...
