Design and Characterization of a Miniaturized Antenna Based on Palisade-Shaped Metasurface

Table 1

Measured property comparison among different antennas with the proposed design.

Designs	Antenna size	−10 dB BW	Peak gain	Frequency
[3]	× 0.34 × 0.34 × 0.05	15%	5.5 dBi	5.0 GHz
[4]	0.97 × × 0.042	16%	6.2 dBi	5.0 GHz
[7]	0.65 × 0.71 × 0.03	6%	7.75 dBi	5.5 GHz
[18]	1.1 × 1.1 × 0.03	12.5%	9.2 dBi	5.5 GHz
[19]	1.3 × 1.3 × 0.06	28.4%	8.2 dBi	5.0 GHz
Proposed	0.55 × 0.69 × 0.08	19.6%	7.43 dBi	5.0 GHz

Note: the antenna size is evaluated relative to the wavelength at the center frequency. Some of the size information is not directly given in the literature and is roughly assessed based on the antenna prototype.
