Design Analysis of High Gain Wideband L-Probe Fed Microstrip Patch Antenna

Abstract

Abstract-A new high gain wideband L-probe fed inverted EE-H shaped slotted (LEE-H) microstrip patch antenna is presented in this paper. The design adopts contemporary techniques; L-probe feeding, inverted patch structure with air-filled dielectric, and EE-H shaped patch. The integration of these techniques leads to a new patch antenna with a low profile as well as useful operational features, as the broadband and high gain. The measured result showed satisfactory performance with achievable impedance bandwidth of 21.15% at 10 dB return loss (VSWR ≤ 2) and a maximum gain of 9.5 dBi. The antenna exhibits stable radiation pattern in the entire operating band.

A Dual-Band High Gain Antenna Based on Split Ring Resonators and Corrugated Plate

“…In the last few years, the wireless communication system has been improved rapidly, and multi-frequency antennas with high-performance are needed to meet the requirement [1,2]. Great attention has been paid to the metamaterials, especially split ring resonators (SRRs), because of their specific properties which have not been discovered in nature [3,4].…”

Design of a High-Gain Cavity-Backed Slot Antenna With Mushroom Cells and Bent Ground Walls

“…Superstrates are also used for gain enhancement [4][5][6][7]. However, these antenna structures are either complicated or having thick profiles.…”

A Shorted Magneto-Electric Dipole With Γ-Shaped Strip Feed

“…Several types of antennas, such as log-periodic [1] and reflector antennas [2], are limited by their large dimensions for these applications. Microstrip patch antenna can provide unidirectional patterns and has major advantages of low profile, low cost, light weight and easy fabrication [3][4][5][6][7][8], but its impedance BW is not wide enough at the condition of stable unidirectional radiation patterns.…”
