Summary This work aims to provide an electrically small reconfigurable antenna with modification in the radiating strip length to switch between 5G mid‐band and 4G band‐40 application. Initially, the length of the radiating strip is designed to operate at 3.5 GHz for 5G mid‐band applications. Using switch configuration, the length of the radiating strip is modified so that the antenna's resonant frequency shifts from 3.5 GHz to 2.32 GHz, which can be operated at 4G band‐40. The effective radiation remains the same at two resonant modes. In terms of size, the proposed antenna geometry is (16.5 × 10.5 × 1.6) mm3. The designed antenna with an electrical length of 0.7014 mm is electrically small in size in comparison with the works of literature. Antenna structure provides a gain of 0.69 dBi and 1.35 dBi at resonant frequencies 2.32 GHz and 3.5 GHz, respectively. The geometry of the antenna is straightforward, and the prototype is fabricated on a low‐profile FR4 substrate. The simulated results are validated experimentally.

A low profile and compact two‐port antenna is proposed for mmWave 5G access point applications. Since the overall space inside a typical mmWave 5G access point is limited, a small form factor based antenna module is proposed. The two‐port antenna shares a common radiator that miniaturizes the overall antenna module. The proposed antenna comprises of single‐layered asymmetric coplanar strip (ACS)‐fed shared radiator with wide operating bandwidth ranging from 25 to 31 GHz that accounts for fractional bandwidth of 21.4%. The two‐port antenna elements are oriented at right angles to each other for obtaining orthogonal pattern diversity (OPD) thereby obtaining wide angular coverage in the E‐plane. Vertical linear corrugations with varying lengths are incorporated for decreasing mutual coupling between these two antenna elements and producing a uniform high gain end‐fire radiation pattern. Isolation of around 4 dB is enhanced by insertion of these vertical corrugations. The proposed antenna attains peak gain of 7.2 dBi with high pattern integrity over the entire operational frequency band. The presented OPD antenna occupies overall area of 74.75 mm2 which is minimal. Moreover, implementation of the proposed antenna inside a typical mmWave 5G access point is also demonstrated. Simulation and measured results are presented with adequate technical explanation.
