Slot coupled microstrip patch antenna

The monopole antenna is modified using microstrip transition in the feedline and block with a triangular-shape slot on each side of the circular patch to produce wider impedance bandwidth with better return loss.

Slot-Coupled Microstrip Patch Antenna Array Synthesizer

Aperture coupled microstrip slot antenna couples the patch antenna with microstripline through an aperture. Introduction: At microwave and millimeter wave frequencies microstrip slot antenna (1) becomes very small & lightweight. In spite of these advantages, it has main disadvantage of back radiation; which limits its use in mobile communication.

Aperture Coupled Patch Antenna Design Methods - Cal Poly represents patch antenna impedance effects coupled through the ground plane slot, while the LC circuit represents ground plane slot resonant behavior and patch edge fringing field effects. Fig. 2 shows an equivalent circuit model for the aperture coupled patch antenna. Nominal antenna circuit model parameters are determined Microstrip Patch Antennas - EM Lab Microstrip Patch Antennas Slide 18 The rectangular patch is the most widely used configuration for microstrip patch antennas. Transmission-Line Model It is the easiest approach to model and analyze the microstrip patch antenna. It is also less accurate, but gives a good physical insight. EM Cavity Model EFFECTS OF SLOTS ON MICROSTRIP PATCH ANTENNA

Microstrip antennas stand out to be distinct in all types of antennas having low cost, less weight, smaller size and easy to fabricate as per requirement.

An Introduction of Aperture Coupled Microstrip Slot Antenna

Abstract: Slot-coupled microstrip patch arrays fed by rectangular overmoded cavities are described and their radiation characteristics analysed using simplified cavity models both for the illuminating and patch resonant cavities. In particular, 4/spl times/4 single cavity-fed and 8/spl times/8 stepped cavity-fed patch arrays were built and studied.

reduced by removing the direct contact between the feed and patch. Slot coupled microstrip patch antenna, shown in Figure 1.1.d is proposed by Pozar in 1985, [2]. It is also a noncontacting feed method. The structure consists of two dielectric layers, which may have different thickness and dielectric constants.
