A compact stacked Quasi-fractal microstrip antenna for RFID applications
In this paper, we propose a new compact quasi-fractal shaped microstrip antenna that consists of a hexagonal patch as the main radiator and a complementary stacked patch as the parasitic element. The overall surface of the proposed quasi-fractal patch is about 55% lower than the conventional hexagonal patch. Using of stacked technique, the gain reduction of compression technique is almost compe...
متن کاملBroadband Stacked Microstrip Patch Antenna for L-Band Operation: FDTD Modeling
This paper presents a novel implementation of an electromagnetically coupled patch antenna using air gap filled substrates to achieve the maximum bandwidth. We also propose an efficient modeling technique using the FDTD method which can substantially reduce the simulation cost for modeling the structure. The simulated results have been compared with measurement to show the broadband behavio...
متن کاملThe Danish polarimetric SAR for remote sensing applications
This paper presents the Danish polarimetric SAR system, EMISAR, and the approach taken in the system design to achieve a reliable high performance system. The design and implementation of the antenna system as well as the analog and digital hardware are discussed. The SAR utilises a dual polarised microstrip antenna with probe fed patches and the antenna exhibits a modified cosec-squared patter...
متن کاملDual Polarization Stacked Microstrip Patch Antenna Array With Very Low Cross-Polarization
This paper describes the development and performance of a wideband dual linear polarization microstrip antenna array used in the Danish high-resolution airborne multifrequency polarimetric synthetic aperture radar, EMISAR. The antenna was designed for an operating frequency of 1.25 GHz 50 MHz and was built as an array of 8 2 probe-fed stacked microstrip patches. The feeding network is construct...
متن کاملWideband Stacked Square Microstrip Antenna with Shorting Plates
The impedance bandwidth of a probe-fed microstrip antenna (MSA) is inherently narrow. Therefore, many approaches to increase the bandwidth such as using additional microstrip resonators [1], stacking parasitic patches above a fed patch (stacked MSA) [2] and embedding a U-shaped slot in the radiating patch [3], etc. have been proposed. It is desirable for wideband antennas that the frequency cha...
