The multi-band microstrip antennas are realized by cutting more than one slots at an appropriate position inside the patch or by placing the open circuit stub on the edges of the patch or by using the combination of slots and stub. In this paper, an analysis to study the multi-band response in stub loaded two half U-slot cut rectangular microstrip antenna is presented. The first half U-slot in ...

In this paper, a novel compact frequency-reconfigurable monopole antenna with switchable symmetric slot structure is presented. The frequency-reconfigurable capability of the antenna is achieved by using a switchable slotted structure on the ground plane. The designed antenna has a simple structure and compact size of 40X40 mm . The antenna, which supports most applicable frequency bands above ...

Design of rectangular microstrip patch antenna (RMPA) using stepped cut at four corners for broadband/multiband application is presented in this paper. Stepped cut at four corner technique is used in order to increase the bandwidth and gain of the antenna. Design and simulation of Modified rectangular microstrip patch antenna are done by CST Microwave Studio software. Four stages are presented ...

This paper describes the antenna design for RF power harvesting system. The design goes through three phases designing of antenna, matching network and rectifier. A dual band Microstrip antenna suspended above ground plane is designed to operate in GSM 1.8 and ISM 2.4 GHz bands. The antenna incorporates the capacitive feed strip which is fed by coaxial probe technique where the inductive impeda...

Local Area Augmentation System (LAAS) based on multiconstellation GNSS can provide improved accuracy, availability and integrity needed to support all weather category II and III precision approach landing of aircraft. In order to receive satellite signals of GNSS, an antenna working over wide frequency band and high phase center stability is preferred. Commonly used antennas like crossed dipol...

in this paper, a novel directional super wide band micro strip antenna based on a simple and new geometry has been proposed. the antenna exhibits the widest bandwidth ever reported to the authors’ knowledge from 50 ghz to 200 ghz. its radiation pattern is approximately steady in the frequency ranges of 50 ghz to 200 ghz. the antenna consists of a club-like radiating patch, a combination of thre...

A circularly polarized single feed microstrip slot antenna has been introduced in this paper as a candidate for use in GPS applications. The slot structure of the proposed antenna has been created on the radiating patch in two steps. At first, a 45 degree rotated square has been etched at the center of the patch, and then a Sierpinski gasket type of the 3rd iteration occupies the resulting slot...

This article proposes a quad band patch antenna for mobile communication. The design requirements are to meet the 0.9 GHz, 1.8 GHz, 2.1 GHz and 2.45 GHz bands. The proposed antenna consists of a rectangular patch monopole printed antenna in which slotting technique is used to achieve multi band resonance. The Patch with three slotted lines generates four resonating frequencies to cover 0.9 GHz ...
