  • Microstrip Antennas (MSA)

    2147 Words  | 9 Pages

    Microstrip antennas (MSAs) have a conducting patch printed on a microwave substrate. Some of the most commonly used shapes are square, circular, triangular, semicircular, sectoral, and annular ring shapes. Radiation from the MSA can occur from the fringing fields between the periphery of the patch and the ground plane. The MSA has proved to be an excellent radiator for many applications because of its several advantages [KPRAY] which is listed below. • They are lightweight and have a small volume

  • Radar Cross Section Research Paper

    861 Words  | 4 Pages

    Radar cross section (RCS) or echo area or effective area is the measure of target’s ability to reflect radar signals in the direction of the radar receiver i.e. it is the measure of the ratio of the backscattered power per steradian in the direction of the radar to the power density that is intercepted by the target [1]. RCS is a measure of how detectable an object is with the radar. The IEEE dictionary of electrical and electronics terms[1]defines RCS as a measure of reflective strength of a

  • Antenna Transmitter Research Paper

    824 Words  | 4 Pages

    In electronics, an antenna is an electrical apparatus that will modify electric power to radio waves or vice versa. It is often being use as a transmitter and receiver. Antenna transmitter will send an alternating current that is in radio frequency to radiate the electromagnetic energy to electromagnetic waves. Antenna receiver will receive the power of an electromagnetic wave to produce a tiny voltage at the terminal to be amplified. The shape and size of the antenna’s structure will decide how

    NAME: CHRISTOPHER MBAH SID: 200964926 ELEC5451M Electronics Laboratory Session (3) A SUPERHETERODYNE RECEIVER. The objective of this lab session was to design a simple superheterodyne receiver and investigate the mixer circuit, the IF filter and the demodulator/audio output. The basic operation of the superheterodyne receiver revolves around the process of mixing. From last week’s experiment with mixers, I know that when two signals are multiplied together, the output is the product of the instantaneous

  • Filtonna Research Paper

    1552 Words  | 7 Pages

    AND ITS BACKGROUND 2.1 Introduction to Filtenna A Filtenna is the integration between filters and antennas, where the antenna acts as the last resonator of the filter. Filtering antennas can be used to reject a certain band of frequencies or to enhance the bandwidth and selectivity. Filtenna can be designed in two ways: design the filter and antenna independently or using co-design both filter and antenna in the same time. Integration of microwave components leads to reduction in circuit size, high
