The fifth-generation (5G) era has already arrived and many applications are prospering. The multiple input multiple output (MIMO) system is the key to enhancing channel capacity for both the fourthgeneration (4G) wireless communication and 5G systems. For a smartphone, the most challenging task for antenna engineers is to accommodate the numerous 4G and 5G multi-port antennas while avoiding mutual coupling problems (Li Y et al., 2009, 2012; Hong, 2017; Sharawi et al., 2017). Therefore, implementing multiple antennas within a small space is a worthwhile topic to study, especially for antennas operating at the same frequency.

Reconfigurable antennas are becoming a major antenna technology for future wireless communications and sensing systems. It is known that, with a single linear polarization (LP) reconfigurable antenna element, a preferred polarization can be produced from a set of multiple polarization states, thus improving the quality of the communication link. This paper presents a new concept of a polarization programmable reconfigurable antenna array that consists of a number of polarization reconfigurable antenna elements with a finite number of possible polarization states. By employing a new optimization strategy and programming the polarization states of all the array elements, we demonstrate that it is possible to realize any desired LP in the vectorial array radiation pattern with accurate control of sidelobe and crosspolarization levels (XPLs), thereby achieving the desired polarization to perfectly match that of the required communications signal. Both numerical and experimental results are provided to prove the concept, and they agree well with each other.

Antenna-in-package system integrated with meander line antenna based on LTCCtechnology

Frontiers of Information Technology & Electronic Engineering 2016, Volume 17, Issue 1, Pages 67-73
We present an antenna-in-package system integrated with a meander line antenna based on low temperature co-fired ceramic (LTCC) technology. The proposed system employs a meander line patch antenna, a packaging layer, and a laminated multi-chip module (MCM) for integration of integrated circuit (IC) bare chips.A microstrip feed line is used to reduce the interaction between patch and package. To decrease electromagnetic coupling, a via hole structure is designed and analyzed. The meander line antenna achieved a bandwidth of 220 MHz with the center frequency at 2.4 GHz, a maximum gain of 2.2 dB, and a radiation efficiency about 90% over its operational frequency. The whole system, with a small size of 20.2 mm×6.1 mm×2.6 mm, can be easily realized by a standard LTCC process. This antenna-in-package system integrated with a meander line antenna was fabricated and the experimental results agreed with simulations well.

A novel wideband ring antenna for polarization/pattern diversity Correspondence
Li SUN, Shigang ZHOU, Guanxi ZHANG, Baohua SUN
Frontiers of Information Technology & Electronic Engineering 2022, Volume 23, Issue 6, Pages 975-983 doi: 10.1631/FITEE.2100421
We present a novel wideband ring antenna for polarization/pattern diversity. The proposed antenna consists of eight printed dipole elements in the form of a circular array. The arms of adjacent elements overlap for capacitive loading. Unlike traditional circular arrays, a method of exciting elements in the form of every two intervals is first introduced. We prove that this method can maintain the wideband characteristics of the antenna. Four independent feeding ports in a ring antenna aperture are designed for the polarization/pattern diversity with suitable feeding networks. As an example, a wideband dual-polarized antenna was designed based on the proposed ring antenna. To achieve two orthogonal linear polarizations with maximum radiation in the direction, two adjacent elements are extracted periodically to feed through one port. The differential feeding network and integrated Baluns have been designed to realize broadside radiation patterns, considering impedance and phase matching. Because the proposed antenna is hollow, it is a good candidate for a multiband sharing aperture antenna element. Results show that the proposed antenna has an overlapped bandwidth of 50.5% (1.04–1.82 GHz) with voltage standing wave ratio (VSWR)<2 for the two polarizations, and port isolation less than 23 dB. The measured realized gain ranges from 6.1 to 8.1 dBi, with stable broadside radiation patterns over the operating frequency band.

Engineering 2023, Volume 23, Issue 4, Pages 157-169 doi: 10.1016/j.eng.2022.09.011
This paper investigates two novel polarization- and pattern-diversity glass dielectric resonator antennas (DRAs), both of which are for tri-band (2.4, 5.2, and 5.8 GHz) wireless fidelity (WiFi) applications. It also investigates what type of diversity antenna is most suitable for WiFi router applications by comparing the two DRAs, along with a new space-diversity glass DRA. These three diversity glass DRAs are also compared with a commercial space-diversity monopole pair to benchmark the performance of the glass DRA in WiFi router applications. In our polarization-diversity antenna, a double-port feeding scheme is developed to excite different DRA modes. The frequencies of the DRA modes are tuned by using a stepped DRA. For the pattern-diversity design, a stacked DRA is introduced to broaden the bandwidth for both the conical and broadside radiation modes. All three of the new diversity antennas were fabricated and measured to verify the simulations. In our experiment, the bit error rate (BER) of the three diversity glass antennas and the reference space-diversity monopole antenna was also measured, and the results are compared and discussed. It is found that the polarization-diversity omnidirectional DRA has the most stable BER among the three.
