In this paper, a Rectangular Monopole Antenna (RMPA) with offset microstrip feed is presented. The structure is fabricated on an FR4 substrate with a dimension of 28 × 32 × 1.6 mm 3 . The proposed structure achieves multiband operation by engraving 2 Complementary Split Ring Resonators (CSRRs) and a C-Shaped slot. Also, 2 Split Ring Resonators (SRRs) are printed on the adjacent sides of the radiating element. The parametric analysis is used to determine the optimum position of the feed and other critical parameters. The proposed structure operates at 2.25 GHz, 3.86 GHz, 4.60 GHz, 5.64 GHz, 5.86 GHz, 6.94 GHz, 7.48 GHz, and 9.47 GHz. The permeability of the SRR and permittivity of the CSRR are extracted and presented. The proposed antenna is fabricated and measured. The measured results of S 11 , radiation pattern, and gain are on par with the simulated results. The proposed antenna's simulated surface current and efficiency are also presented to validate the performance. Simple structure, stable radiation pattern, multiband operation, reasonable gain, and efficiency are the significant features of the proposed RMPA.

“…[19][20][21] The polarization diversity for dual polarized proximity-fed antennas can achieve adequate levels of isolation over the shared impedance bandwidth of both T x and R x ports. [19][20][21] The additional isolation can be achieved through analog/RF domain SIC topologies like single or multiple-taps, which sample the signals from T x port and subtract these processed signals from R x port. 8,[22][23][24][25][26] Inherently, the single-tap SIC topology achieves narrow band isolation due to stringent signal inversion requirements.…”

This work presents two dual polarized proximity-fed monostatic patch antennas with improved interport isolation for 2.4 GHz industrial, scientific and medical band same frequency full duplex wireless applications. The presented antennas achieves the high interport decoupling through intrinsic isolation of the polarization diversity in conjunction with a simple single-tap and two-taps self-interference cancellation (SIC) topologies. The polarization diversity isolation is achieved through two perpendicular microstrip feeds for proximity feeding to excite orthogonal polarization mode for transmit (T x) and receive (R x) modes. The prototype for proposed antenna with integrated single-tap and two-taps SIC circuit is tested to record its interport isolation, impedance bandwidths and gains for both T x and R x ports. The implemented antenna with single-tap SIC circuit demonstrates 10 dB return-loss bandwidth of ≥100 MHz for both T x and R x ports. The measured isolation exceeds 40 dB over the 40 MHz bandwidth. Moreover, the recorded peak isolation is better than 74 dB for implemented antenna prototype. Furthermore, the 40 MHz bandwidth with 40 dB isolation can be tuned with the help of SIC-tap as demonstrated through the experimental results. The measured gain levels are around 4.6 dBi for both T x and R x port. The same antenna structure with integrated two-taps SIC topology features better than 55 dB isolation within 10 dB return loss bandwidth of 100 MHz. The peak isolation exceeds 97 dB and isolation levels are better than 60 and 80 dB over 50 and 20 MHz bandwidths, respectively, for presented antenna with two-taps SIC configuration. The compact antenna offers comparatively wider impedance and isolation bandwidth with improved SIC levels compared to previous designs.

With the rapid development of satellite communication, satellite navigation, and wireless communication systems, multiband antennas are widely studied for military and commercial applications. To cover multiple frequency bands, we designed a multiband and wideband microstrip patch antenna with four multiple concentric rings fabricated on upper layer. Meander, fractals, and feeders covered with magnetic material could be beneficial to achieving relatively lower frequency bands. The novel layout optimizes the space utilization of the antenna and excites at multiple resonant modes. As a result, the proposed structure could obtain 7 operating bands of 0.
