Ultra-Wideband Antennas for Wireless Communication Applications

Table 3

A brief comparison of applied UWB antennas for communication applications.

Antennas	Advantages	Disadvantages	Prototypes
Stacked patch antenna [60]	Good radiation characteristic; Allowing a suitable time-domain characteristic	Directive; Complicated structure
Vivaldi antenna [67]	Can yield a large bandwidth	Complicated structure
Wide-slot antenna [48]	Can obtain a wide impedance bandwidth if the distance between the radiating arms and ground place is selected properly	Large size at the frequency band of interest
Taper slot antenna [67]	(i) High gain at high frequency; (ii) Symmetric beamwidths	High cross-polarization level
Printed elliptical monopole antenna [88]	(i) Wide bandwidth can be achieved; (ii) Simple structure; (iii) Size suitable array design; (iv) Height—few mm; (v) Easily mounted on ordinary plastic casing; (vi) Broadside radiator with an omnidirectional radiation pattern; (vii) 3D radiation pattern
