Improved Analytical Model for a Proximity Coupled Microstrip Patch Antenna (PC-MSPA)

Analysis of Proximity Coupled Microstrip Patch Antenna for Wireless Applications

In this article, an analysis of dual band proximity couple stacked microstrip patch antenna has been proposed. The theoretical investigations of antenna parameters such as return loss, gain and radiation pattern are calculated. It is found that antenna resonate at two distinct modes at lower and upper resonance frequencies, i.e. TM01 and TM02. The bandwidths of the proposed antenna are compared...

Dual Band Aperture Coupled Stacked Microstrip Patch Antenna for WLAN

This paper presents a dual band aperture coupled stacked microstrip antenna with the introduction of an air gap 3 mm between the ground plane and the upper layer substrate for WLAN applications. The nominal antenna has – 10 dB return loss bandwidth of 134.8 MHz and 384.9 MHz at lower band resonant frequency of 3.905 GHz and upper band resonant frequency of 5.36 GHz respectively. The gain of the...

A Capacitive Fed Microstrip Patch Antenna with Air Gap for Wideband Applications (RESEARCH NOTE)

In this paper a microstrip antenna on a suspended substrate with capacitive feed is presented. capacitive feed is created by a slot within the rectangular patch around the feed point. The proposed antenna exhibits a much higher impedance bandwidth of about 47% (S11 < −10 dB). Effects of key design parameters such as the air gap between the substrate and the ground plane, the gap width between r...

Frequency-Reconfigurable Stacked Patch Microstrip Antenna Using Aperture-Coupled Technique

This paper presents a novel structure of a frequency-reconfigurable microstrip antenna fed with an aperture-coupled technique and stacked patch technology. The proposed antenna design has a unique structure; the radiating elements (top and bottom patch) are sorted in stacked substrate layers to indicate the different operating frequencies. One PIN diode switch integrated at the feedline is reco...
