Here, a multi‐band microstrip‐fed antenna is presented. The compact size of the antenna is 32 × 18 mm2, which makes it attractive to mobile devices. Antenna prototype is fabricated using FR4 dielectric material with dielectric constant 4.4 and thickness 1.6 mm. The radiating patch of the antenna consists of four hook‐shaped rings and truncated ground‐plane helps to achieve good impedance matching. A very compact microstrip feedline is utilized to couple electromagnetic energy to radiating patch. The measured S11 ≤ ‐10 dB of the multiband antenna is achieved at the GSM 1800 /1900 MHz, Bluetooth 2.4 GHz, WLAN 2.4/5.2 GHz and WiMAX 2.5/3.5/5.5 GHz bands. The antenna's performance reveals that it operates in several bands, has a high gain, and radiates in an omnidirectional pattern. Simulated and measured results are presented to show good accommodation. In addition, to have a good view and better show the innovation presented in this article, the suggested multi‐band monopole antenna is compared to various previously presented multiband microstrip antennas using the Analytic Hierarchy Process approach which is an accurate and fair method for selecting the best candidate and is used a lot in various cases.

“…Many similar antennas have been proposed, often with dimensions too enormous for practical application [3,4]. A large and very complex radiating patch used in [3] and in [4] a CPW fed antenna using two stepped impedance resonators are presented. There were additional suggestions for some compact antennas [5][6][7][8][9][10].…”

“…To overcome the interference, several techniques for band notch purposes have been introduced. Employing different shapes of the slots is one the very common techniques to obtain desired band notches . Employing parasitic‐coupled elements to reject a band , and using various type of resonators are the other known techniques that have been reported in literature .…”

An electromagnetically coupled elliptical antenna for UWB systems with a parasitic element to reject band of 5–5.9 GHz is presented. The triangular cuts in parasitic element provide a good control of bandwidth. A slot antenna inside the parasitic element has been introduced to stimulate the rejected band (5–5.9 GHz) separately. Proposed structure has printed on a substrate of FR4 with dimensions of 24 × 22.5 × 1 mm3. Measurement results prove the functionality of the proposed structure. © 2017 Wiley Periodicals, Inc.

“…Most of these references focused on designing antennas with one notch characteristic expected for [18]. However, some papers with multiple notches are reported in [25][26][27]. In this paper, with a novel approach of combining the mentioned methods, a four notched ultra wideband antenna is presented.…”
