“…For example, an inverted L-shaped slot is included in the ground plane [2], while U-shaped [3], W-shaped [4], hat-shaped [5], and cup-shaped [6] slots are incorporated in the radiating patch. Antennas with dual- [7–9], triple- [10, 11], and quad- [12, 13] notched characteristics by using different combinations of various slots have also been reported. Although incorporation of slot structures is a simple and popular approach, other options such as introducing parasitic strips above the ground plane [14], use of split-ring resonators [15], and Hilbert curves [16] are also found to be very effective at notch out the desired frequency band.…”

This paper presents the design and analysis of a miniaturized, coplanar waveguide-fed ultra-wideband monopole on-chip antenna with band-notch characteristics. By incorporating a “U”-shaped slot in the feedline, a band-notch is realized in the frequency range of 7.9–8.4 GHz to avoid interference from the X-band uplink satellite communication system. The proposed antenna achieved good voltage standing wave ratio (VSWR) characteristics with VSWR value <2 for the frequency range of 2.5–20.1 GHz excluding the band-notched frequencies. The fractional bandwidth and bandwidth ratio are obtained as 156% and 8.04:1, respectively. Dominant factors that affect the center frequency and bandwidth of the notched band are thoroughly investigated. This paper addresses both frequency as well as time domain behavior of the proposed structure. Standard 675 µm thick, high resistive silicon substrate (ρ≥8 kΩ-cm, εr = 11.8, and tan δ = 0.01) is used to design the proposed compact antenna structure with a layout area of 8.5 × 11.5 mm2. Fabrication process steps along with simulated and measured data are presented here. A close analogy between simulated and measured data is observed.

“…The incorporation of the slot is the preferable option getting notch characteristics for its simple design implementation step. Antennas with single [6][7][8][9][10], dual [16][17][18], triple [15,19], and quad [20,21] notch bands by using different combinations of various slots have been reported in the recent decades. Researchers working in this domain are now aiming to extend the antenna's operating bandwidth beyond the UWB region to cope with today's modern high-speed data communication [22].…”

This paper presents a CPW-fed, UWB-extended bandwidth, dual band-notched on-chip antenna with its equivalent circuit model. The UWB-extended bandwidth is realized by truncating the bottom corners of a rectangular patch radiator while a 90 • -rotated 'C'-shaped slot in the patch and a 'U'-shaped slot in the feedline are used to achieve two notch bands for mitigating the signal interference in the frequency bands of 5.15 to 5.925 GHz and 7.9 to 8.8 GHz. Based on the fundamental theory, different parasitic as well as distributed circuit parameters associated with the designed on-chip antenna are extracted, and then the corresponding equivalent circuit model is configured from them. The resultant circuit is validated with the well approved full-wave electromagnetic simulation result and is found in close approximation with each other.

“…To overcome the problem of mutual coupling, different decoupling structures are designed in [7][8][9][10]. UWB system also has some electromagnetic interference with coexisting narrow bands, thus different notch structures are presented to stop this interference [11][12][13][14][15][16][17][18][19][20][21][22][23].…”

A compact pot-shaped Multiple Input Multiple Output (MIMO) Antenna with triple notched band characteristics is presented for Ultra Wide Band (UWB) applications. The comprehensive dimension of the presented antenna is 17 × 32 mm 2 . The presented antenna has two identical potshaped radiators, 7-shaped stubs, T-shaped strips, M-and C-shaped slots. Two novel 7-shaped stubs are connected to the antenna ground plane to obtain −22 dB enhanced isolation. The presented antenna works from 2.95 to 12.1 GHz with triple stopped WiMAX, WLAN, and X bands. A novel T-shaped strip is connected to the antenna ground plane to stop the WiMAX band (3.3-4.4) GHz. C-and M-shaped slots are etched in the antenna radiators to stop WLAN (5.20-6.12) GHz and X (7.6-8.15) GHz bands, respectively. The peak gain of the proposed antenna is from 1.5 to 5 dB with a radiation efficiency of 80-90%. The Envelope Correlation Coefficient (ECC) of the proposed antenna is less than 0.01 with a Diversity Gain greater than 9.99 except for the notched bands.
