AB  - A multi-band compact rectangular microstrip patch antenna is proposed for IEEE 802.11 standards.
Proposed antenna covers all five distinct frequency ranges 2.4 Ghz (IEEE 802.11 b/g/n), 3.65 GHz
(IEEE 802.11 y), 4.9 Ghz (IEEE 802.11 j), 5 GHz (IEEE 802.11 a/h/j/n/ac) and 5.9 GHz (IEEE 802.11 p) bands. The
design frequency is 2.42 GHz applicable for WLAN, UMTS and Wi-MAX application. The three resonance
frequencies are observed to be 2.58, 3.74 and 5.12 Ghz. The return loss of proposed antenna
is -16.41 dB at 2.42 GHz and -33.28, -15.6 and -19.02 dB at respective resonance frequencies. The simulated
fractional -10 dB bandwidth of lower, middle and upper resonance frequencies are 42.25% (1.829-2.809 GHz),
10.9% (3.487 -3.889 GHz) and 20.89 % (4.844-5.974 GHz), respectively. The maximum gain, directivity, antenna
efficiency and radiation efficiency of proposed antenna are 6.05 and 6.6 dBi, 94.91 and 98.56%, respectively. The
experimental fractional -10 dB bandwidth are 52.42% (2.28-3.9 GHz) and 11.01% (5.15-5.75 GHz) with 2.85 and
5.43 GHz resonance frequency respectively. Both simulated and experimental results of proposed antenna cover
all five frequency ranges issued by IEEE 802.11 WLAN standards which show good agreement. The analysis
of rectangular patch antenna is performed with strip line feed by using IE3D mentor graphics simulation
software.
