Dual-Polarized Slot-Coupled Planar Antenna With Wide Bandwidth
A new dual-polarized slot-coupled microstrip patch antenna is presented, which can achieve high-isolation low crosspolarization levels, a wide bandwidth, and low backward radiation levels. The coupling slot is an H-shaped slot. For wide bandwidth and easy integration with active circuits, it uses the slot-coupled stacked microstrip patches. The theoretical analysis is based on the finite-differ...
متن کاملRectangular Ring Microstrip Patch Antenna for Ultra-wide Band Applications
ABSTRACT: The printed antenna is one of the best antenna structures, due to its low cost and compact design. In this paper, we present a new approach to improve the radiation effectiveness and the performance of antennas by miniaturization of the size. Indeed, we have studied the performance of ultra wideband antenna which consists of a ring-shaped patch. This study was made for the whole frequ...
متن کاملDual-Band Annular-Ring Microstrip Patch Antenna for Satellite Applications
A dual-band circularly polarized antenna fed by four apertures that covers the bands of GPS, Galileo, is introduced. The ARSAs designed using FR4 substrates in the L and S bands have 3-dB axial-ratio bandwidths (ARBWs) of as large as 37% and 52%, respectively, whereas the one using an RT5880 substrate in the L band, 61%. In these 3-dB axial-ratio bands, impedance matching with VSWR<=1.8 is also...
متن کاملCircular Ring Loaded Monopole Dual Band Patch Antenna
Abstract— Miniaturized structure and multiple band performance of a patch antenna are primary requirements for modern wireless communication systems. In this paper, a novel design of monopole dual band microstrip patch antenna with circular ring has been proposed for S and C band applications. For dual bands (4.0 GHz and 4.68 GHz), proposed patch antenna shows quite satisfactory radiation perfo...
متن کاملDual Band Slotted Patch Antenna for On/Off-body Communication
Body Centric Wireless Communication (BCWC) has been topic of much research in recent years. In this manuscript, a novel low-cost microstrip patch antenna is designed for on-/off-body communication with a dual-band operation. The proposed structure exhibits a monopole-like radiation pattern at 2.45 GHz and a broadside radiation at 4.8 GHz, simultaneously. Lateral dimensions of 42 mm × 46 mm and ...
